Abstract
This study aimed to assess genetic parameters for four distinct traits - days to 50% flowering, pod length (cm), pod diameter (cm), and plant height (cm)in the rabi seasons of 2021 and 2022. The investigation encompassed 40 pea genotypes, and a pooled analysis of variance indicated significant variations in all the examined traits. The findings of the current study lead to the conclusion that plant height in peas is primarily influenced by additive gene action, implying that this trait can be enhanced through straightforward selection methods. In contrast, both additive and non-additive approaches are necessary for the improvement of pod length and pod diameter. Specifically, days to 50% flowering is predominantly governed by nonadditive gene action, indicating that the enhancement of this trait would be better achieved through heterosis breeding techniques. These insights into the genetic control mechanisms of these traits provide valuable guidance for breeding strategies, emphasizing the importance of selecting appropriate methods tailored to the underlying genetic architecture of each trait for optimal improvement outcomes.
