| Abstract | ||||
| The present study aims to assess the variability and to clarify genetic analysis of vegetative, yield and its components traits as well as infestation of three insect pests in peas through 6 × 6 half-diallel mating design under Sohag conditions. All genotypes, apart from both Boogie and Snow Wind cultivars (which resistant to the three insects), showed moderately resistance to at least one insect, with varying degrees of severity, regardless of yield, could therefore be used as in breeding programs. Two crosses, i.e., (P4 x P5) and (P4 x P6) showed highly significant desirable SCA effects and heterosis for yield along with earliness, no. of branches, stem length, pod length, pod width, no. of seeds/pod, thrips and leafminer resistance, indicating the possibility of combine each of high yield, good qualities and insect pests’ resistance. Genotypes P4 x P5, P1 x P4 and P4 x P6 along with the two semi-leafless cultivars, i.e., Boogie and Snow Wind are particularly noteworthy as a leading candidate for breeding programs in regions or seasons where these insects are widespread, owing to its robust resistance. Conversely, genotype Progress 9 should probably be approached with caution or avoided in breeding programs because of its significant susceptibility. | ||||
