Abstract:
Field pea (Pisum sativum L.) oldest cultivated, most important nutritious food legume of the world and a major pulse crop of winter season. The present investigation was carried out to access genetic variability parameters for better understanding of genetic architecture of seed yield and its attributes in field pea. Twelve parents (9 lines + 3 testers) of field pea were crossed in L x T mating design and the parents along with their 27 hybrids were grown in randomized block design with three number of replication during rabi 2020-21. Narrow differences between PCV and GCV of different traits implying apparent variability present among genotypes not only due to genetic factor but also environment play a crucial role in expression of these traits. Low heritability coupled with low genetic advance were observed for most of traits expect days to maturity, height of first pod and plant height suggesting that these traits are genetically controlled by non-additive gene action and heterosis breeding would be rewarding for these traits.
