Genetic variability, correlation and path analysis for green pod yield and its components in garden pea

摘要

High heritability coupled with high genetic advance were noticed through pod yield per plant, plant height and 1000 seed weight suggesting that these characters could be considered reliable indices for selection to enhance the green pod yield. The phenotypic and genotypic coefficient of variations were observed highest in plant height, number of pods per plant, first flowering node and pod yield per plant, which indicted the highest level of variability in these traits and also indicates that there is ample scope for effective improvement through selection. Correlation studies revealed that pod yield per plant was significantly and positively associated with number of pods per plant, number of grains per pod and pod length. Path analysis studies revealed that pod yield per plant had highest positive contribution with number of grains per plant followed by pod length and number of pods per plant.
