GENETIC ANALYSIS OF YIELD AND SOME CHARACTERS IN PEAS

In this research, the genetic structure was investigated by using the Jinks-Hayman analysis type in terms of agronomical characteristics of the parents and their crosses which were evaluated from 5 X 5 reciprocal diallele pea population. The means of investigated characteristics was done by using variance. According to the results of diallele analysis, the variance of additive gene was found nonsignificant for all the investigated characteristics. The variance of dominance was found significant for all the characteristics except 100 seed weight. There were the effect of dominance for all the characteristics in accordance with D-H-1 difference. Genetic variance components population and interjacent rate estimating and regression graphic analysis for Wr and Vr values were made for whole characteristics. The analysis for some agronomic characteristics showed that the population had a sufficient level of genetically variation. Additionally, the recessive genes had more effects on plant height and seed per plant, dominant genes had more effects on number of pods, seed per pod, 100 seed weight and seed yield in population.
