Genotype by environment interaction in mutant lines of winter barley for grain yield
Abstract. The study was conducted to analyze grain yield performances of twenty eight mutant barley lines, two new feed barley varieties and two check varieties, between 2011 – 2014 growing seasons. The experimental layout was randomized complete block design with four replications. Additive main e...

| description | Abstract. The study was conducted to analyze grain yield performances of twenty eight mutant barley lines, two new feed barley varieties and two check
varieties, between 2011 – 2014 growing seasons. The experimental layout was randomized complete block design with four replications. Additive main effects
and multiplicative interactions analysis (AMMI) revealed that the yield performances of genotypes were under the main environmental effects of genotype by
interactions. The first two interaction principal component axes (IPCA 1 and IPCA 2) were significant and cumulatively contributed to 89.84% of the total
genotype by environmental interaction. Вoth the GGE and AMMI1 biplots identified G9 as the highest yielding mutant line among the studied genotypes
showing relative stability and can be recommended for further evaluation for variety release. In addition, G30 and G26 had high stability with high grain yield
and they were identified to be a valuable source for yield improvement in winter barley breeding programs. |
