| Abstract | ||||
| GENETIC diversity was examined in relation to heterosis. Five Egyptian faba bean cultivars were crossed in a full diallel mating system to produce twenty hybrids. The multivariate analysis of diversity based on six characters related to productivity indicated the existence of considered genetic diversity and showed genotypes into five clusters by two methods analysis of genetic distances based on RAPD analysis and Euclidean distances based on mean values of studied agronomy traits. Parents and their F1 hybrids were distributed into different clusters. Results of the RAPD technique by using five primers showed a great extent of significant variations with 67.59% polymorphism percent and a high number of unique bands. Sakha 1 and Giza 843 cultivars have a good effect on most studied traits in their hybrids. H13, H17 and H18 are a superiority hybrids; it has high positive significant values of heterosis percentage over mid parents for all yield and yield components traits. While H19 and H20 hybrids have positive significant heterosis for all studied traits except 100 seeds weight. | ||||
