Agronomic performances, disease reaction and yield stability of field pea (Pisum sativum L.) genotypes in Bale Highlands, Ethiopia

Sixteen field pea (Pisum sativum L.) genotypes were evaluated using Randomized Complete Block Design (RCBD) with four replications for evaluating agronomic performance, reaction to diseases (downy and powdery mildew and ascochyta blight), genotype x environment interaction (GEI) and yield stability across 12 environments during 2004-2006 at highlands of Bale, South eastern Ethiopia. In this study various statistical methods of analyzing agronomic performance, disease reaction and yield stability were used. The analysis of variance (ANOVA) for agronomic characters revealed that there was highly significant (
