Abstract:
Grasspea (Lathyrus sativus L.) is considered an "insurance crop" due to its credible yields during drought and flood conditions. This study investigated the genetic variability among grasspea accessions during the Rabi season of 2022-23 using thirty-six genotypes with two checks. Observation was carried on fourteen yield-related characteristics are used to assess genetic variability. Analysis conclude that all characters were highly significant except days to maturity and days to 50% flowering, indicating the genotypes under test have enough variability. All traits had PCV values larger than GCV values, showing the impact of environment on the way characters are expressed. The biological yield/plant, pod bearing length, seed yield/plant, no. of pods/plant, no. of effective pods/plant, harvest index, ODAP content and hundred seed weight all showed high heritability along with high genetic advance, indicating additive gene action and the potential for selection to increase seed yield.
