Quantifying genotype × environment interaction effect and yield stability under different environmental conditions is very important challenge in plant breeding programs. The aim of this study was to quantify genotype × environment interaction effect on grain yield and grain yield stability of barley promising lines in temperate regions of Iran. Nineteen promising barley lines (G1-G19) along wi...

In agricultural experimentation, a large number of genotypes are normally tested over a wide range of environments (locations, years, growing seasons, etc.) and the underlying statistical and genetical theories used to model this system may be rather complicated. The occurrence of the genotype (G) X environment (E) interaction effect further complicates the selection of superior genotypes for a...

GGE (genotype + genotype×environment) biplot is one of the new graphical methods to study genotype×environment interaction in which the effects of genotype and G×E interaction are not separated and selection is based on both of these effects. In the present research, GGE biplot was used to study 14 safflower genotypes over six research stations under water stress and non-stress conditions in sp...

polymorphism of the b-lactoglobulin (b-lg) gene in 101 cows belonging to the holstein herd and a superior cow, producing more than 150 kg milk/day, together with four offsprings was investigated by the polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) method. in the holstein herd, the alleles a and b of the b-lg gene had frequencies of 0.53 and 0.47, respectively. th...

Late spring frost is one of the most important factors causing loss of production of the Persian walnut (Juglans regia L.). Therefore, the selection of spring frost tolerant genotypes has been among the most important priorities in the breeding programs during the recent years in Horticultural Science Research Institute, Karaj-Iran.  After the spring frost in 2010, five superior genotypes (B10,...

This study was conducted to estimate stability of yield in forage sorghum varieties for identifying varieties with combine stability and high yield potential across two cropping conditions. Thus, seven forage sorghum varieties were evaluated for three years under two cropping conditions including spring (E1) and summer (E2) cropping, using a randomized complete block design with four replicatio...

main objective in wheat breeding programs is to improve high yielding and stable varieties possessing desirable morpho-physiological traits. this study was conducted to determine the stability of 18 winter and facultative bread wheat genotypes. the experiments carried out in 9 experimental stations (karadj- arak- ardebil- jolgerokh- miandoab- hamedan- mashad- qazvin- khoy) using a randomized co...

This study was conducted to investigate the phenotypic diversity of 108 pure barley lines in Augment design with four controls in six blocks in the farm of Darab Agricultural Research Station (2020-2021). In order to select the best lines in terms of yield and other traits, SIIG index was used. The results of restricted maximum likelihood (REML) analysis showed that the lowest and highest level...
