AbstractThe experiment has carried out in the Field Crop Dept. College of Agriculture and Forestry, Mosul University by using Randomized Complete Block Design R.C.B.D with three replications, during two growing seasons 2008/2009 and 2009/2010. To evaluate the performance of Full-Diallel hybrids resulting from employing Full-Diallel crossing system among four varieties in field pea viz, 1-Ariare, 2-Nisere, 3-Marike and 4-Messire. The study aimed to determine the best parental combinations through estimating the effects of general and specific combining abilities of the studied genotypes. The results indicated that general combining ability was significant for all studied character except no. of branches per plant and green pods yield, and that specific combining ability was significant for all studied character except no. of days to flowering and maturity. The reciprocal effects was significant for all studied character except no. of pods per plant, average pod weight and 100 seed weight. The results showed that specific combining ability was higher than general combining ability for all the studied characters, by which indicated the presence of dominance gene action for those character. Marike variety showed high general combining ability for most of the studied characters, and therefore contains the desired gene. The hybrids varied for their specific combining abilities effects and this due to the wide genetic diversity between their parents.
