Genotype – environment interaction study in sugar beet (Beta vulgaris L.) (original) (raw)

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.

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 by Environment Interaction Effects on the Crop of Sugar Beet (Beta vulgaris L.) Using Multivariate Analysis

Asian Journal of Research in Crop Science, 2022

Evaluation of genotypes under Egyptian desert conditions comes in the first order for the Plant Breeding and Conservation Program of the Desert Research Center (DRC). The objective of this study was to analyze the effect of the genotype by environment interaction of sugar beet across various locations using multivariate models. Data for studied traits of sugar beet were obtained from experiments at three regions: Saint Catherine, South Sinai Governorate (E1); Baloza station, North Sinai Governorate (E2); and East El-Qantra station, El-Ismailia Governorate (E3) in Egypt. All examined traits were significantly impacted (p <0.05 or 0.01) by environment (E), genotypes (G), and their interaction (GEI) using the AMMI model, with the exception of root length/plant by the environments as well as leaves weight/plant and total soluble solids percentage % traits by the genotypes. GEI was partitioned into two principal components (PCs), which were significant for all studied traits (P < 0.05 and P < 0.01). The highest variability from the total variance was recorded by environmental influences for leaves weight/plant and total soluble solids percentage % traits, as Original Research Article

Genotype by environment interaction components underlying variations in root, sugar and white sugar yield in sugar beet (Beta vulgaris L.)

Euphytica, 2018

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 (

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.

Assessment of Coefficient of Variation, Correlations Between Yield and Yield Attributes in Sugar Beet (Beta Vulgaris L.)

2018

An experimental study was conducted to evaluate the genetic variation and relationship between yield and its components in sugar beet. The existence of high PCV and GCV estimates for the morpho-biochemical traits indicated greater possibility of their improvement through selection in respective environments. High estimates of heritability and genetic advance were recorded for SRW and RY. In case of biochemical traits, most of the characters exhibited significant phenotypic or high order genotypic correlations in positive direction. In contrast, Brix and SC recorded strong negative association at both levels with high order positive genotypic correlations with yield contributing traits. In over all consideration, SRW, RL, RD and SC emerged as most important direct yield components owing to their high order positive direct effects at phenotypic as well as genotypic level.

Comprehensive evaluation of sugar beet genotypes for yield and relative traits by multivariate analysis

SVU-International Journal of Agricultural Sciences, 2021

Among few methods suggested for evaluation of the genotype-environment interactions (GE interaction), the AMMI method (Additive main Effect and Multiplicative Interaction) is the most instructive model. The objective of this experiment was to estimate the G×E interaction in sugar beet varieties of stability and adaptability through different environments using the AMMI model. As well as cluster analysis was automated to identify the interrelationships among the tested varieties, also Principal component analysis (PCA) was used to define the relationship between the studied traits. Twenty genotypes of sugar beet were evaluated at two locations (El-Dakahlia and El-Fayoum stations) in Egypt in two seasons (2018/2019 and 2019/2020). A randomized complete block design with three replications was used in each environment. Results showed that the AMMI analysis of variance was highly significant differences for the environment, variety, and their interactions. Based on AMMI model, Glorius, Florima, Capel, Belatos, Classic and Toro genotypes in EN3 (Dakahlia 2019/2020), have the highest sugar yield, respectively. Results of cluster analysis demonstrated an extensive genetic diversity among the tested varieties, also the 1 st sub cluster, (cluster I) was recorded high values of root weight, length, diameter and total weight. It was found that cluster II (Farida, Toro, Capel, Florima, Betamax, Glorius) recorded the highest root and sugar yield, which led to increase of 106.66% and 112.91% higher than that compared with cluster V (Lilly, Heba, Mirador). According to PCA results, PCA1 accounted for 69.5% of the total phenotypic variation expressed and PCA2 accounted for 27.03% of the variation. Characters accounting for the most of difference expressed in the PCA1 were root weight and root diameter. While the main traits in PCA 2 were root weight and root length.
