| Abstract | ||||
| This experiment was conducted at Shandaweel Agricultural Research Station - Agricultural Research Center during the winter season of 2021/2022, to study the performance of thirteen selected genotypes (families) in the F4 generation of two peas populations under two levels of irrigation water (100% normal irrigation recommended and 50% from irrigation water quantity recommended). The design used in the experiment was a split-plot design with three replicates, where irrigation levels (100% of the recommended irrigation water quantity and 50% of the recommended water quantity for pea irrigation) were on the main plots, while the thirteen peas genotypes (families) from each population were randomly distributed on the split plots. The results of the statistical analysis of the data showed that irrigation levels had a significant effect on most of the studied traits in the two populations, except for the No. of days to 50% flowering and the No. of branches per plant in population II, the shellout% in population I, and the pod filling% in both populations. The highest mean values of fresh pod weight per plant (114.98 and 108.22 g) were obtained at 100% of the normal irrigation level in populations I and II, respectively. The lowest mean values (102.37 and 95.69 g) for this trait were obtained at 50% of the irrigation level (water stress) in populations I and II, respectively. The genotypes (families) in peas had a significant effect on all the studied traits. Where genotype (family) # 1 recorded the highest mean values of fresh pod weight per plant (175.44 and 162.93 g) in populations I and II, respectively. The genotype (family) # 13 gave the lowest mean values (66.04 and 65.87 g) for this trait in populations I and II, respectively. The interaction between irrigation levels and genotypes (families) had a significant effect on all the studied traits. Where the interaction between 100% normal irrigation level and genotype (family) #1 gave the highest mean values of fresh pod weight per plant (182.15 and 180.98 g), while the interaction between 50% recommended irrigation level and genotype (family) #13 recorded the lowest mean values (60.54 and 62.57 g) for this trait in populations I and II, respectively. | ||||
