Genotype – environment interaction study in sugar beet (Beta vulgaris L.)
2016
The research was carried out to study the response of 16 cultivars of sugar beet in 3 seasons at one major sugar beet producing location, Hama, in Syria in autumn time, and assess genotype by environment interaction, and to estimate the stability of the varieties performance, according to the yield stability statistics (Ysi), for the studied traits of these varieties. A randomized complete block design with four replications was used. Data collected from each experiment were subjected to simple analysis of variance and after homogenization of error variance, combined analysis for four traits including Sucrose content (SC %), Purity (P %), Root yield (RY ton.ha -1 ), and Sugar yield (SY ton.ha -1 ) were carried out. Combined analysis of variance over years, exhibited significant differences (P≤0.05) among the varieties. Results of yield stability statistics (Ysi) revealed that five of the monogerm sugar beet varieties (Vico, Dita, Al Ceste, Chimene, and SR305) were stable for all of ...
Yield Stability Parameters of Sugar Beet ( Beta vulgaris L . ) Cultivars in Iran
2006
The present study focused on estimating yield stability of sugar beet cultivars in Iran. The data were collected from pilot studies on imported and domestic cultivars. Twenty-one cultivars of sugar beet were compared in 12 main spring growing regions of Iran in 2014, in randomized complete block design, with three replications. The effect of location and cultivar was significant (P≤0.05) on root yield. Among the cultivars, Pauletta and Fernando had the highest root yield (75.880.5 t/ha), followed by SBSI034 and BTS 335 (70 t/ha), whereas Canaria, Rasta, Torbat, Novodoro, Tucan, Morly, Aria, Pars, Antec, Nagano, Rosier, Iris, Flores, Boomrang, Sanetha, and Ekbatan had the lowest root yield (56.267.2t/ha). The significance of location × cultivar interaction (P≤0.05) showed that cultivars did not have uniform performance at different locations. Estimation of different stability parameters revealed that Fernando, Pauletta, SBSI-034 and BTS-335 had high root yield and stability, while Bo...
Genotype × Environment Interaction for Characteristics of Some Sugar Beet Genotypes
Journal of Plant Production
In order to study the effect of genotype × environment interaction and stability of sugar beet genotypes for seven cultivars, viz Lilly, DS 9004, Gazella, Oscar Poly, Pather, Toro and Hercule. A field trail was sown in eight environments as major four locations (Sakha, Giza, El-Fayoum and Malawy) for two years (2011/12 and 2012/13) using a randomized complete block design, with three replications. Analysis of variance for root yield, sugar yield and sugar content showed that the environment and genotype and genotype × environment interaction (GEI) were significant. GEI were evaluated by two methods (phenotypic stability and AMMI model). According to phenotypic stability analysis results, genotype (Lilly) was the most stable for sugar content and root and sugar yield. This genotype recorded the highest root and sugar yield (30.34 and 5.22 ton/fed, respectively) across environments, and Sakha environment had the highest mean values of environments followed by El-Fayoum environment. AMMI model explained most of the genotype × environment interaction (85.97%, 83.34 % and 86.47 %) for root yield, sugar content and, sugar yield, respectively. Lilly was the best genotype based on the biplot, and showed specific adaptation to Sakha and El-Fayoum location. The varieties Pather, Hercule and Toro were the lowest variety among the evaluated varieties and it is better not to use it in the studied areas. The genotypes Gazella, Oscar poly and DS9004 had an average genetic potential for the studied traits, but its high general adaptability, then it could be introduced for all areas. Among the locations, Sakha was the best location, and was more similar to El-Fayoum. Meanwhile, Malawy was the poorest location. Therefore, two stability methods confirmed that Sakha and El-Fayoum are recommended as suitable regions for sowing sugar beet and Lilly variety could be suggested as the best genotype for these locations. Meanwhile, AMMI method showed new information.

J. Biol. Chem. Environ. Sci., 2018
Field experiment was carried out in three locations, Agricultural Research Stations in governorates of Ismailia (latitude of 30° 58′N and longitude of 32 o 26′E), Faiyum (latitude of 29 o 18′ N and longitude of 30 o 35′E), and Alexandria (31° 21′N latitude and longitude of 29° 91′E), Egypt in 2016/2017 and 2017/2018 seasons. The present work included thirty six treatments, twelve sugar beet varieties (Beta vulgaris, L.) namely Beta 303, LP 1003, Beta 273, Pyramid, Sible, Beta 401, Beta 302, Univers, Nancy, Bairac, Oscar poly and LP 016 and three locations to evaluate them under Egyptian conditions and select the best in terms of suitability to environmental conditions and the extent of their superiority in yielding, technological traits and stability. The experiment was carried out in a randomized complete block design (RCBD) with three replications. Results showed that Ismailia location surpassed the other two locations, producing roots with high content of sucrose% and less content of impurities compared with Faiyum and Alexandria. Results indicated that varieties significantly differed in the studied traits except Quality index and impurities%. Pyramid variety exhibited the superiority over the other tested varieties which recorded the highest values of root yield (ton/fed.) Differences between Pyramid variety and Beta 273, LP 1003 and Beta 303 varieties did not reach significant level. With regard, in sugar yield Pyramid variety in 1st season and LP 1003 variety in 2 nd season surpassed the other varieties without significant difference with Beta 303.
Evaluation of Ten Exotic Sugar Beet Varieties under Different Locations in Egypt
Evaluation of crop varieties in different locations comes in the first order for our Department due to its importance in determining this adaptation, especially sugar beet where the Egyptian climatic conditions are unfavorable for its floral induction, which led to import its seeds annually from abroad especially from Europe. So, we need to optimize imported cultivars production by evaluation and adaptation under Egyptian conditions. A comparative study was conducted to assess the performance of ten exotic sugar beet varieties in three locations in Egypt. Soils of the experimental locations were clay, sandy clay and sandy texture. Results showed that, all sugar beet varieties showed different behavior with respect to sugar %, fresh root and gross sugar yield under three locations. Maximum fresh root beet yield was produced by Monte Rose (34.08 ton fed -1 ) followed by Rosana (33.02 ton fed -1 ) and DS-9007 (32.65 ton fed -1 ), which were grown in clay soil, Swallow (35.20 ton fed -1 ), Rosana (33.00 ton fed -1 ) and Torro (33.21 ton fed -1 ) in sandy clay soil and DS-9004 (31.20 ton fed -1 ) and R-Hist (29.66 ton fed -1 ) in sandy soil. Similar trends were recorded for gross sugar yield. In terms of sucrose %, varieties, Toro, DS-9007 and DS-9004 recorded the highest value (18.00, 19.00 and 17.65%) in clay, sandy clay and sandy soil respectively. Results also, indicated that, the estimated genetic parameters i.e., PCV, GCV,σ 2 P, σ 2 g, σ 2 e, H 2 and GA in clay soil location gave the highest values, followed by sandy clay soil and sandy soil locations of all studied traits, except sandy soil location which showed estimate of PCV and GCV than sandy clay soil location for sucrose % trait and of H 2 for the three studied traits. These results indicated the role of environmental influence across these locations. Also, cluster analysis showed that, the genotypes were grouped into three clusters. The minimum and maximum genetic distance was observed between LP-16 and Disk 01-99 as well as Rosana and Disk 01-99 genotypes, respectively. Based on the mean cluster distance, it was observed that the third group of cultivars (Rosana, Swallow, Monte Rosa and LP-15) and the second group of cultivars (DS 9007, DS-9004 and Toro) are highly dissimilar and genotypes from these two clusters could be evaluated for their combining ability and could be used as parents in heterosis breeding programs of sugar beet. Generally the results illustrated that all tested sugar beet cultivars can be successfully grown in clay, sandy clay and sandy soils in Egypt but we must take into consideration the suitable varieties for each location.
Quality of Some Sugar Beet Varieties Under Different Environmental Conditions
Sinai Journal of Applied Sciences, 2018
Six field experiments were carried out in 2015-16 and 2016-17 seasons. A randomize complete block design with three replications was used at three locations :1. Giza Experiment Station (latitude 30.01 0 N and longitude 31.21 0 E); 2. Tamiya District, Fayoum Governorate (latitude 29.30 0 N and longitude 30.84 0 E) and 3. Ismailia Governorate (latitude 30.36 0 N and longitude 32.16 0 E)]. The performance of six sugar beet varieties (cvs.); Samba, Pleno, Gloria, Poly belga, Oscar poly and Gazella was studied to estimate sugar yield and its contributing traits as well juice quality traits under the three environmental conditions. The obtained results showed that growing seasons had a significant effect on impurities (K, Na and α-amino N), some technological characteristics (purity, extractable sugar, sucrose and sugar lost to molasses percentages) as well sugar yields/fed. The effect of varieties and locations factors significantly affected sugar percentage, extractable and sugar yield. The obtained results indicated that sowing Samba variety in the three locations had the highest sugar extraction and sugar percentages as well as sugar yield/fed. In general, results revealed that Samba variety followed by Gazella is favorable for the regions of Giza, Fayoum and Ismailia Governorates.

The success of plant breeding programs depends on the ability to provide farmers with genotypes with guaranteed superior performance in terms of yield across a range of environmental conditions. We evaluated 49 sugar beet genotypes in four different geographical locations in 2 years aiming to identify stable genotypes with respect to root, sugar and white sugar yields, and to determine discriminating ability of environments for genotype selection and introduce representative environments for yield comparison trials. Combinations of year and location were considered as environment. Statistical analyses including additive main effects and multiplicative interactions (AMMI), genotype main effects and genotype 9 environment interaction effects (GGE) models and AMMI stability value (ASV) were used to dissect genotype by environment interactions (GEI). Based on raw data, root, sugar and white sugar yields varied from 0.95 to 104.86, 0.15 to 20.81, and 0.09 to 18.45 t/ha across environments, respectively. Based on F-Gollob validation test, three interaction principal components (IPC) were significant for each trait in the AMMI model whereas according to F ratio (F R) test two significant IPCs were identified for root yield and sugar yield and three for white sugar yield. For model diagnosis, the actual root mean square predictive differences (RMS PD) were estimated based upon 1000 validations and the AMMI-1 model with the smallest RMS PD was identified as the most accurate model with highest predictive accuracy for the three traits. In the GGE biplot model, the first two IPCs accounted for 60.52, 62.9 and 64.69% of the GEI variation for root yield, sugar yield and white sugar yield, respectively. According to the AMMI-1 model, two mega-environments were delineated for root yield and three for sugar yield and white sugar yield. The mega-environments identified had an evident ecological gradient from long growing season to intermediate or short growing season. Environment-focused scaling GGE biplots indicated that two locations (Ekbatan and Zarghan) were the most representative testing environments with discriminating ability for the three traits tested. Environmentally stable genotypes (i.e. G21, G28 and G29) shared common parental lines in their pedigree having resistance to some sugar beet diseases Electronic supplementary material The online version of this article (
Root Yield and Quality of Sugar Beet (Beta vulgaris L.) in Relation to Plant Population
Journal of Agronomy and Crop Science, 1998
Introduction of genetic monogerm seed and the advancement of agricultural techniques raised the possibility of eliminating costly thinning operations in sugar beet farming. However, this requires high and uniform seedling emergence to provide prerequisite plant populations in the field. This work investigated the minimum levels of seedling emergence for non-thinned sugar beet farming. The experiment was carried out in a loamy soil to investigate the effects of three levels of emergence (60, 50 and 35%) and two intra-row spaeings (8 and 15cm) with or without thinning using seed source of graded viability of cv Eva in 1992 and 1993 under field conditions in Eastern Anatolia. Plant population throughout the growing period was monitored and data were taken of yield and quality parameters. On average, 60, 50 and 35% emergence levels were achieved using seed source of 90, 72 and 54% viability range, which resulted in different levels of plant stands depending on intra-row spacing and thinning, Piant density at harvest ranged between 49 500 and 124 500 ha ' on average depending on initial establishment, intra-row spacing and thinning. Root yield and sugar yield were the highest at plant stands between 90000 and 100000 ha ', below or above of which declined. Impurity contents (e.g. Na, K and a-amino N contents) and extractable sugar content decreased but sugar content and clear juice purity enhanced as plant stands at harvest increased.
Effect of Genotype on Morphological and Quality Features of Sugar Beet
The Journal "Agriculture and Forestry", 2019
The importance of sugar beet is great because it gives root yield of about 50 t ha-1 and 30-40 t of fresh leaves and heads of beet that is used for feeding cattle. In the Republic of Serbia are favorable agro-ecological and soil conditions for the production of sugar beet. In the structure of total arable land of the Republic of Serbia, sugar beet accounts for about 2% where 94% of it is in Vojvodina, which has the most favorable climate and soil conditions, tradition and proximity of capacities for root production and processing. In addition to its adaptability to climatic conditions, sugar beet reacting quickly to changes in meteorological factors which greatly affect root yield and sugar content. In the three-year trials it was examined morphological characteristics and the amount of a-amino N in five genotype of sugar beet. According to the survey results, the largest number of leaves at the genotypes at technological maturity had the genotype Otis (35.33) while the smallest had had genotype Severina (15:53). Genotype Otis, as a whole, had the highest leaf area (X =10193.13 and Xmax = 11483.79), and the lowest had genotype Severina (X = 4242.33; Xmin = 3982.44). The lowest average value of the amount of α-amino N indicators were found for Chiara and Laetitia (X = 2.23). The observed traits were largely depended on the genotypes and years. Genetic variation is necessary for successful breeding.
