Abstract

This research was conducted at the experimental farm of Northern Highlands Research Station El-Errh–Sana’a an area located about 15 km North of Sana’a during two years 2022 -2023.Seed of three pea genotypes which were entered into a diallel cross scheme during the winter season 2022and gave six 6 F¹ Hybrids, to induce variability preference favored for some agronomic traits and planted to obtain F¹ generation in 2022 summer season. Sixty-eight individual plants were selected from F² populations based on morvologecal plant type, The selected segregations were primary evaluated in three replications as F³ generation in 2023 winter season.  The results showed that using the genotype (Sa’id) as a mother and the genotype (Umran-1) as a father resulted in a significant number of pods in their reciprocal hybrids. The results also showed that the hybrids were characterize by high heterosis existing of genetic variation in the first segregating generation. The estimation of broad-sense heritability in the second and third segregating generations for the studied traits (days to 50% flowering, number of pods/plant, plant height, hundred seed weight and sees yield/plant) was high. This indicates that these traits are useful due to their high heritability, and therefore can be relied upon to follow the genetic segregations and study their genetic stability, which will inherit desirable traits and characteristics, such as resistance to lodging and high grain yield in pea crop.
