Stability analysis for fodder yield of oat (Avena sativa L.) genotypes using univariate statistical models under diverse environmental conditions in Ethiopia

Oat (Avena sativa L.) is one of the most important dual-purpose cereal crops cultivated under diverse environmental conditions in Ethiopia. The fodder dry matter yield stability analysis was conducted using twenty-four oat genotypes across nine environments in a randomized complete block design with...

Description
Summary:Oat (Avena sativa L.) is one of the most important dual-purpose cereal crops cultivated under diverse environmental conditions in Ethiopia. The fodder dry matter yield stability analysis was conducted using twenty-four oat genotypes across nine environments in a randomized complete block design with three replications. The study aimed to evaluate the magnitude of genotype by environment interaction and determine the stability of oat genotypes for fodder yield using 14 univariate stability parameters. The pooled analysis of variance revealed that the genotype, environment, and their interaction effects had variation (p
