Inheritance of Some Agronomic Characters in Pea

Abstract

This study was conducted by using Jinks-Hayman type analyses on four pea genotypes (PS4009, PS3053, PS3073 and Reyna) and their population of the complete diallel reciprocal crosses in order to examine the genetic structure. According to the results of all diallel crosses, environmental variance (E) and additive gene variance (D) was not significant. All the features of the dominant gene variances were higher than the additive gene variances (H1) and D-H1 value was found to be negative. In the population, dominant genes were found significant for all the characteristics except number of seed per pod. Result of Wr, Vr graphics indicated partial dominancy for the number of seed per pod, and over dominancy for the rest of the characters studied.
