Abstract
Nine genotypes of peas were grown in a randomized complete block design with three replications for two growing season, to study their performance, genetic and yield contributing characters. Combined analysis results exhibited no significant differences between the two growing seasons, and this proved that all the genotypes were homozygous, while there was high significant differences for most of the characters. There was high heritability accompanied by high expected genetic advance expressed as percentage of mean for the characters in respect of plant height, number of pods per plant, number of seeds per plant, 1000 seeds weight and yield, this is due to high variability among the studied genotypes. Grain yield was found to be positively correlated with plant height pod length, pod weight ,number of seeds per plant and 1000 seeds weight. Hence mass selection can be practiced for further improvement.
