Assessment of Variability and Association among Green Forage Yield and Contributing Traits in Indigenous Genotypes of Grass Pea [Lathyrus sativus (L.)]

Abstract

Forty-four variable local accessions of grasspea including advanced lines and three checks were investigated. Observations were recorded from 5 selected plants of each genotypes in 3 replications. Estimates of GCV and PCV were high for leaflet width, number of primary branches and plant height indicating higher genetic variation in the genotypes studied. High heritability coupled with high genetic advance as percent of mean was observed forleaflet width, number of primary branches L/S ratio, plant height, length of primary branch, pods per plant.Significant positive correlation of green forage yield per plant (g) with dry matter yield per plant (g), length of primary branch (cm), leaflet width (cm), at genotypic and phenotypic level respectively. In path analysis green forage yield was considered as dependent trait, Maximum positive direct effects was shown by DMY followed by days to first flowering, pods per plant, number of primary branch, plant height, leaflet width, leaflet length, length of primary branches.
