Evaluation of Genetic Performance and Estimation of some Genetic Parameters in Yield Traits and Components of Four Genetic Structures of Broad Bean Under the Influence of Different Levels of Soil Salinity

Abstract

Abstract The study was carried out with the aim of evaluating the genetic performance and estimating some genetic parameters in the characteristics of the yield and its components for the four different structures originating from Broad bean (local, Turkish, Spanish and Dutch) under the influence of different levels of soil salinity (2, 6 and 9 ds\m) in the field of the Field Crops Department of the Faculty of Agriculture - Al-Qasim Green University During the growing season of 2022/2023, the experiment was carried out according to the design of the complete random sectors as a factor experiment and with three replicates. The results of the analysis of variance showed significant differences between the four structures of all the traits studied. The Turkish variety significantly outperformed the rest of the other varieties in all the characteristics studied Number of pods (10.12 pods / plant), the number of seeds per pod (4.06 seeds / pod) and the weight of 100 seeds (121.22 g) and the yield of seeds (1.59 tons / ha) and the biological yield (3.19 tons / ha) and protein yield 322.4 kg / ha). pod) weighing 100 seeds (135.02 g), seed yield (2.42 tons/ha), biological yield (4.42 tons/ha) and protein yield 0.507 ton/ha), The results showed that the phenotypic and genetic variations were high for all traits at the level (2 ds/m) but decreased at the salt level (9 ds/m). The percentage of inheritance in the broad sense was very high for all traits and all salt levels, which indicates that the phenotypic variation between the varieties was mostly genetic.
