Efficiency of various stability models for ranking barley genotypes

Efficiency of various stability models for ranking barley genotypes

Twenty-two barley populations were tested under eight environments to determine genotype-environment interactions. Eberhart and Russell (1966). Perkins and Jinks (1968) and Freeman and Perkins (1971) models provided similar ranking with respect to both responce (b) and stability (s2d) for most of th...

Description
Summary:Twenty-two barley populations were tested under eight environments to determine genotype-environment interactions. Eberhart and Russell (1966). Perkins and Jinks (1968) and Freeman and Perkins (1971) models provided similar ranking with respect to both responce (b) and stability (s2d) for most of the traits. Ranking under ecovalence was similar to that of Eberhart a nd Russell model. F2 and/or F3's were more stable and responsive. Different stability mechanisms appeared to beinvolved in the determination of the grain yield stability.
