Eight open-pollinated confectionary sunflower populations and two open-pollinated confectionary sunflower cultivars used as control varieties were evaluated during two growing seasons. Certain agronomical and technological traits such as plant height, head diameter, seed yield, 1000-seed weight, kernel ratio, crude protein ratio and crude protein yield were measured. The results for the individual years and the combined data for both years revealed that there were significant positive correlations between the seed yield and the plant height, head diameter, 1000-seed weight and crude protein yield. The crude protein yield was also positively and significantly correlated with the 1000-seed weight and the seed yield, but the correlations with the plant height, head diameter, kernel ratio and crude protein ratio were not significant. The path coefficients from path analysis indicated that the seed yield had the maximum positive direct effect on the crude protein yield, followed by the crude protein ratio. The greatest positive indirect effects on the crude protein yield were attributed to the 1000-seed weight, plant height and head diameter through their effects on seed yield. The magnitudes of the direct effects of the seed yield and the crude protein ratio on the crude protein yield were 79.2% and 56.9%, respectively. Selection based on seed yields, 1000-seed weights and crude protein ratios could be used to improve crude protein yield in confectionary sunflower breeding programs.

A rainfed (non-irrigated) treatment as the control and 13 different irrigation treatments (H, F, M, HF, HM, FM, HFM, H 60 FM, H 40 FM, HF 60 M, HF 40 M, HFM 60 , HFM 40) with full (about 360 mm) or limited (40 and 60%) irrigation water, were applied to the hybrid Sanbro (Novartis Seed Company) planted on clay soil, at three critical development periods: heading (H), flowering (F), and milking (M). Evapotranspiration (ET) increased as an increasing amount of irrigation water was applied. The highest seasonal ET (an average of 674 mm) was measured in the HFM treatment. Limited irrigation applied at different growing periods had different effects on the yield-related characters examined. The highest seed yield (4056 kg ha À1) and oil yield (1841 kg ha À1) were obtained from the HFM treatment; 85.4 and 88% increases, respectively, compared with the control. The seed yield and oil yield increases for the limited-irrigation treatments were: 78.7 and 77.4% for H 60 FM; 77.4 and 78.9% for H 40 FM; 72.2 and 75% for HF 60 M; 76.4 and 79.2% for HF 40 M; 72.7 and 73.6% for HFM 60 ; 77.6 and 79.1% for HFM 40. Therefore, we confirm that HFM irrigation is the best choice for maximum yield under the local conditions, but these irrigation schemes must be reconsidered in areas where water resources are more limited. In case of more restricted irrigation, the limitation of irrigation water at the flowering period should be avoided.

As the N rates increased, all of the traits measured significantly increased, except the crude oil content, under both irrigation treatments. Based on the 2-year average, the highest seed yield (2713.6 to 2751.2 kg ha-1) and crude oil yield (1012.7 to 1042.5 kg ha-1) were obtained using 160 kg ha-1 N and the higher N rates, with increases of 47.8% and 39.4%, respectively, compared to the control (0 kg ha-1 N). Similar trends were also obtained for the other traits, except the crude oil content, which was the highest (39-41%) at 0 kg ha-1 N but the lowest (36-38%) under the higher N rates. The highest mean values for the crude protein content and 1000-seed weight were obtained under the highest N rates (200 and 240 kg ha-1 N). In 2007, the economic optimum nitrogen rate (EONR) for sunflower was 148.5 kg ha-1 N under non-irrigated conditions, as compared with 190.0 kg ha-1 N with irrigation. In 2008, the EONRs for sunflower under non-irrigated and irrigated conditions were 145.1 and 176.7 kg ha-1 N, respectively. Although the EONR for irrigated conditions was approximately 30-40 kg ha-1 N more than that for non-irrigated conditions, the seed yield under the irrigation conditions was approximately 65-79% higher compared with the non-irrigated conditions. As a result, it was determined that the economic optimum N rate for sunflower was 145-150 kg ha-1 N under non-irrigated conditions and 177-190 kg ha-1 N under irrigated conditions.

Çalışmada, 5 hat ve 5 tester line x tester melezleme yöntemine göre melezlenmiş, böylece 25 F1 hibridi genetik analizler için geliştirilmiştir. Bursa Uludağ Üniversitesi Ziraat Fakültesi tarafından geliştirilen 10 ebeveyn hat ve 25 F1 dölünden oluşturulan hibrid populasyonunda korelasyon ve path analizleri yapılmıştır. Araştırmada % 50 çiçeklenme gün sayısı, olgunlaşma gün sayısı, bitki boyu, tabla çapı, 1000 tane ağırlığı, ham protein oranı, yağ oranı ve yağ verimi gibi belirli agronomik ve teknolojik özellikler ölçülmüştür. Sonuçlar tane verimi ile bitki boyu, tabla çapı, 1000 tane ağırlığı, % 50 çiçeklenme gün sayısı ve yağ verimi arasında pozitif yönde önemli korelasyonlar olduğunu ortaya koymuştur. Öte yandan, tane verimi ile yağ oranı, ham protein oranı ve olgunlaşma gün sayısı arasındaki ilişkiler istatistiksel olarak önemsiz bulunmuştur. Path analizinden elde edilen Path katsayıları tane verimi üzerine tabla çapının en yüksek pozitif yönde doğrudan etkiye sahip olduğunu ve bunu yağ veriminin negatif yöndeki doğrudan etkisinin izlediğini göstermiştir. Tabla çapı ve yağ veriminin tane verimine doğrudan etkilerinin büyüklüğü sırasıyla % 51.7 ve % 43.5'tir. Bununla birlikte, yağ verimi tabla çapı üzerinden % 50.5'lik payla pozitif yönde en yüksek dolaylı etkiye sahip olmuştur. Bu sonuçlar, tane verimini arttırmak için yapılacak ıslah programlarında, tabla çapı, bitki boyu, % 50 çiçeklenme gün sayısı ve 1000 tane ağırlığı için pozitif yönde seleksiyonlarla başarılı sonuçlar elde edilebileceğini göstermiştir.

Six artificial hybrids were created using 3 CMS and 2 restorer lines in sunflower (Helianthus annus L.) According to the results, the ratios of GCA:SCA variance were lower than 1 for plant height and head diameter in the both years; for number of seeds per head and 1000 seed weight in 2007 and for seed yield in 2006. For all these characters, non-additive effects were more effective than the other types of polygenetic effects. The additive gene actions were significant for 1000 seed weight and number of seeds per head in 2006 and for plant height and seed yield in 2007, since the ratios of GCA:SCA variances for these characters were greater than 1. The parental lines CMS 10 and RHA 10 proved to be good combiners having the highest positive GCA effect in yield and certain yield components. The crosses CMS 10 x RHA 03, CMS 01 x RHA 10, CMS 10 x RHA 10 and CMS 23 x RHA 10 might be considered as promising hybrid combinations in terms of seed yield . The values of heterosis and heterobeltiosis values ranged from 109.8 to 218.3% for seed yield. All of the tested hybrids showed positive and significant heterobeltiosis for seed yield.

Results over years were combined for final analysis. Above-ground dry matter for common vetch and faba bean green manure crops were 2,300 and 2,587 kg ha −1 , respectively. Mean root dry matter yield of faba bean (285 kg ha −1) was higher than common vetch (120 kg ha −1). Nitrogen (N) yields of common vetch and faba bean green manure crops were 49 and 58 kg N ha −1 for above-ground and 2.0 and 5.0 kg N ha −1 for root dry matter, respectively. Averaged over all nitrogen fertilizer rates, potato plants grown in plots following common vetch and faba bean green manure cover crops produced 12.7% and 15.0% more tuber yield ha −1 , respectively, compared with plants in the winter wheat plots. Potatoes following green manure legume cover crops produced approximately 36 to 38% higher tuber yields compared with potatoes grown following winter wheat when no nitrogen fertilizer was applied. Differences between tubers yields following cover crops decreased as N rates increased. Results over combined 2-years indicated that the economically optimum N rate (EONR) was an average of 30 kg N ha −1 lower for potato following green manure legume cover crops compared with potato following winter wheat cover crop.

The experiments were performed under irrigated conditions in 2014, 2015 and 2016 in four different locations (Adana, Antalya, Izmir and Sanliurfa) of Turkey. Fourteen soybean genotypes consisting of 10 advanced soybean lines and four standard varieties were analyzed by a randomized complete block design with 4 replications. The combined analysis of variance revealed significant (P<0.01) effects for all sources of variation (environment, genotype, and G×E interaction) for the seed yield and yield components. Genotype and environment accounted for about 2.59% and 51.04% of the total variation for seed yield, respectively, while the GE interaction explained 20.84% of the total variation. According to the GGE principle, five mega-environments were formed in the present study. Results of the research revealed that genotypes G8 (KANA), G9 (KASM 02), G11 (ARISOY), G3 (BATEM 306), G1 (BATEM 207) and G12 (ATAEM 7) were found as stable. According to GGE Biplot analysis for all traits and genotypes, G4 (BATEM 317) had the largest values for plant height, first pod height, days to 50% flowering, days to maturity and seed yield.

Over two years (2006 and 2007), significant differences for all characters except plant height and crude oil per-cent were found between irrigation regimes (irrigated and non-irrigated conditions) while genotypes showed significant differences for all characters investigated. Also, genotype × irrigation regime interaction was highly significant for all traits except crude oil percent. In addition, year × irrigation regime, year × genotype and year × genotype × irrigation regime interactions were statistically significant for head diameter, 1 000 seed weight, seed yield and crude oil yield. The seed yield and crude oil yield increased highly with irrigations. The seed yield increases for irrigated treatment compared with non-irrigated treatment were 58.3 % in 2006 and 101.4 % in 2007. Compared with non-irrigated treatment, crude oil yield increases for irrigated treatments were 56.9 % in 2006 and 99.4 % in 2007. Differences between genotypes in seed yield and crude oil yield significantly varied according to irrigated and non-irrigated conditions. The control variety, Sanay and experimental hybrid, C 10 × R 10 produced more seed yield and crude oil yield than those of others in irrigated conditions, whereas highest seed yield and crude oil yield was obtained from the control variety, Muson in non-irrigated condition and differences among other hybrids were not statistically significant under rainfed condition.

Eight open-pollinated confectionary sunflower populations and two open-pollinated confectionary sunflower cultivars used as control varieties were evaluated during two growing seasons. Certain agronomical and technological traits such as plant height, head diameter, seed yield, 1000-seed weight, kernel ratio, crude protein ratio and crude protein yield were measured. The results for the individual years and the combined data for both years revealed that there were significant positive correlations between the seed yield and the plant height, head diameter, 1000-seed weight and crude protein yield. The crude protein yield was also positively and significantly correlated with the 1000-seed weight and the seed yield, but the correlations with the plant height, head diameter, kernel ratio and crude protein ratio were not significant. The path coefficients from path analysis indicated that the seed yield had the maximum positive direct effect on the crude protein yield, followed by the crude protein ratio. The greatest positive indirect effects on the crude protein yield were attributed to the 1000-seed weight, plant height and head diameter through their effects on seed yield. The magnitudes of the direct effects of the seed yield and the crude protein ratio on the crude protein yield were 79.2% and 56.9%, respectively. Selection based on seed yields, 1000-seed weights and crude protein ratios could be used to improve crude protein yield in confectionary sunflower breeding programs.

A rainfed (non-irrigated) treatment as the control and 13 different irrigation treatments (H, F, M, HF, HM, FM, HFM, H 60 FM, H 40 FM, HF 60 M, HF 40 M, HFM 60 , HFM 40) with full (about 360 mm) or limited (40 and 60%) irrigation water, were applied to the hybrid Sanbro (Novartis Seed Company) planted on clay soil, at three critical development periods: heading (H), flowering (F), and milking (M). Evapotranspiration (ET) increased as an increasing amount of irrigation water was applied. The highest seasonal ET (an average of 674 mm) was measured in the HFM treatment. Limited irrigation applied at different growing periods had different effects on the yield-related characters examined. The highest seed yield (4056 kg ha À1) and oil yield (1841 kg ha À1) were obtained from the HFM treatment; 85.4 and 88% increases, respectively, compared with the control. The seed yield and oil yield increases for the limited-irrigation treatments were: 78.7 and 77.4% for H 60 FM; 77.4 and 78.9% for H 40 FM; 72.2 and 75% for HF 60 M; 76.4 and 79.2% for HF 40 M; 72.7 and 73.6% for HFM 60 ; 77.6 and 79.1% for HFM 40. Therefore, we confirm that HFM irrigation is the best choice for maximum yield under the local conditions, but these irrigation schemes must be reconsidered in areas where water resources are more limited. In case of more restricted irrigation, the limitation of irrigation water at the flowering period should be avoided.

As the N rates increased, all of the traits measured significantly increased, except the crude oil content, under both irrigation treatments. Based on the 2-year average, the highest seed yield (2713.6 to 2751.2 kg ha-1) and crude oil yield (1012.7 to 1042.5 kg ha-1) were obtained using 160 kg ha-1 N and the higher N rates, with increases of 47.8% and 39.4%, respectively, compared to the control (0 kg ha-1 N). Similar trends were also obtained for the other traits, except the crude oil content, which was the highest (39-41%) at 0 kg ha-1 N but the lowest (36-38%) under the higher N rates. The highest mean values for the crude protein content and 1000-seed weight were obtained under the highest N rates (200 and 240 kg ha-1 N). In 2007, the economic optimum nitrogen rate (EONR) for sunflower was 148.5 kg ha-1 N under non-irrigated conditions, as compared with 190.0 kg ha-1 N with irrigation. In 2008, the EONRs for sunflower under non-irrigated and irrigated conditions were 145.1 and 176.7 kg ha-1 N, respectively. Although the EONR for irrigated conditions was approximately 30-40 kg ha-1 N more than that for non-irrigated conditions, the seed yield under the irrigation conditions was approximately 65-79% higher compared with the non-irrigated conditions. As a result, it was determined that the economic optimum N rate for sunflower was 145-150 kg ha-1 N under non-irrigated conditions and 177-190 kg ha-1 N under irrigated conditions.

Çalışmada, 5 hat ve 5 tester line x tester melezleme yöntemine göre melezlenmiş, böylece 25 F1 hibridi genetik analizler için geliştirilmiştir. Bursa Uludağ Üniversitesi Ziraat Fakültesi tarafından geliştirilen 10 ebeveyn hat ve 25 F1 dölünden oluşturulan hibrid populasyonunda korelasyon ve path analizleri yapılmıştır. Araştırmada % 50 çiçeklenme gün sayısı, olgunlaşma gün sayısı, bitki boyu, tabla çapı, 1000 tane ağırlığı, ham protein oranı, yağ oranı ve yağ verimi gibi belirli agronomik ve teknolojik özellikler ölçülmüştür. Sonuçlar tane verimi ile bitki boyu, tabla çapı, 1000 tane ağırlığı, % 50 çiçeklenme gün sayısı ve yağ verimi arasında pozitif yönde önemli korelasyonlar olduğunu ortaya koymuştur. Öte yandan, tane verimi ile yağ oranı, ham protein oranı ve olgunlaşma gün sayısı arasındaki ilişkiler istatistiksel olarak önemsiz bulunmuştur. Path analizinden elde edilen Path katsayıları tane verimi üzerine tabla çapının en yüksek pozitif yönde doğrudan etkiye sahip olduğunu ve bunu yağ veriminin negatif yöndeki doğrudan etkisinin izlediğini göstermiştir. Tabla çapı ve yağ veriminin tane verimine doğrudan etkilerinin büyüklüğü sırasıyla % 51.7 ve % 43.5'tir. Bununla birlikte, yağ verimi tabla çapı üzerinden % 50.5'lik payla pozitif yönde en yüksek dolaylı etkiye sahip olmuştur. Bu sonuçlar, tane verimini arttırmak için yapılacak ıslah programlarında, tabla çapı, bitki boyu, % 50 çiçeklenme gün sayısı ve 1000 tane ağırlığı için pozitif yönde seleksiyonlarla başarılı sonuçlar elde edilebileceğini göstermiştir.

Six artificial hybrids were created using 3 CMS and 2 restorer lines in sunflower (Helianthus annus L.) According to the results, the ratios of GCA:SCA variance were lower than 1 for plant height and head diameter in the both years; for number of seeds per head and 1000 seed weight in 2007 and for seed yield in 2006. For all these characters, non-additive effects were more effective than the other types of polygenetic effects. The additive gene actions were significant for 1000 seed weight and number of seeds per head in 2006 and for plant height and seed yield in 2007, since the ratios of GCA:SCA variances for these characters were greater than 1. The parental lines CMS 10 and RHA 10 proved to be good combiners having the highest positive GCA effect in yield and certain yield components. The crosses CMS 10 x RHA 03, CMS 01 x RHA 10, CMS 10 x RHA 10 and CMS 23 x RHA 10 might be considered as promising hybrid combinations in terms of seed yield . The values of heterosis and heterobeltiosis values ranged from 109.8 to 218.3% for seed yield. All of the tested hybrids showed positive and significant heterobeltiosis for seed yield.

Results over years were combined for final analysis. Above-ground dry matter for common vetch and faba bean green manure crops were 2,300 and 2,587 kg ha −1 , respectively. Mean root dry matter yield of faba bean (285 kg ha −1) was higher than common vetch (120 kg ha −1). Nitrogen (N) yields of common vetch and faba bean green manure crops were 49 and 58 kg N ha −1 for above-ground and 2.0 and 5.0 kg N ha −1 for root dry matter, respectively. Averaged over all nitrogen fertilizer rates, potato plants grown in plots following common vetch and faba bean green manure cover crops produced 12.7% and 15.0% more tuber yield ha −1 , respectively, compared with plants in the winter wheat plots. Potatoes following green manure legume cover crops produced approximately 36 to 38% higher tuber yields compared with potatoes grown following winter wheat when no nitrogen fertilizer was applied. Differences between tubers yields following cover crops decreased as N rates increased. Results over combined 2-years indicated that the economically optimum N rate (EONR) was an average of 30 kg N ha −1 lower for potato following green manure legume cover crops compared with potato following winter wheat cover crop.

The experiments were performed under irrigated conditions in 2014, 2015 and 2016 in four different locations (Adana, Antalya, Izmir and Sanliurfa) of Turkey. Fourteen soybean genotypes consisting of 10 advanced soybean lines and four standard varieties were analyzed by a randomized complete block design with 4 replications. The combined analysis of variance revealed significant (P<0.01) effects for all sources of variation (environment, genotype, and G×E interaction) for the seed yield and yield components. Genotype and environment accounted for about 2.59% and 51.04% of the total variation for seed yield, respectively, while the GE interaction explained 20.84% of the total variation. According to the GGE principle, five mega-environments were formed in the present study. Results of the research revealed that genotypes G8 (KANA), G9 (KASM 02), G11 (ARISOY), G3 (BATEM 306), G1 (BATEM 207) and G12 (ATAEM 7) were found as stable. According to GGE Biplot analysis for all traits and genotypes, G4 (BATEM 317) had the largest values for plant height, first pod height, days to 50% flowering, days to maturity and seed yield.

Over two years (2006 and 2007), significant differences for all characters except plant height and crude oil per-cent were found between irrigation regimes (irrigated and non-irrigated conditions) while genotypes showed significant differences for all characters investigated. Also, genotype × irrigation regime interaction was highly significant for all traits except crude oil percent. In addition, year × irrigation regime, year × genotype and year × genotype × irrigation regime interactions were statistically significant for head diameter, 1 000 seed weight, seed yield and crude oil yield. The seed yield and crude oil yield increased highly with irrigations. The seed yield increases for irrigated treatment compared with non-irrigated treatment were 58.3 % in 2006 and 101.4 % in 2007. Compared with non-irrigated treatment, crude oil yield increases for irrigated treatments were 56.9 % in 2006 and 99.4 % in 2007. Differences between genotypes in seed yield and crude oil yield significantly varied according to irrigated and non-irrigated conditions. The control variety, Sanay and experimental hybrid, C 10 × R 10 produced more seed yield and crude oil yield than those of others in irrigated conditions, whereas highest seed yield and crude oil yield was obtained from the control variety, Muson in non-irrigated condition and differences among other hybrids were not statistically significant under rainfed condition.
