Summary, etc. Winged bean accessions introduced from diverse sources were grown in a randomised block design with three replications during July to May (1983-84) at College of Horticulture, Kerala Agricultural University, Vellanikkara. The extent of genetic variability, heritability and genetic advance, association among polygenic characters and its partition into direct and indirect effects were estimated. A discriminant function analysis was also carried out to find out the efficiency of selection through discriminant function over straight selection or vice-versa.
The accessions exhibited significant differences with respect to all the characters studied exception being for thickness of stem at the collar region. The green pod yield and number of pods per plant exhibited high values of genotypic and phenotypic coefficient of variation. High heritability value in conjunction with high genetic advance was observed for days to final harvest and number of pods per plant. The content of crude protein was found to be maximum in seeds, followed by leaves, pods, flowers and tubers. The accessions P.T.4 (38.50 per cent) and P.T.30 (38.28 per cent) recorded the maximum protein content in green pod.
Green pod yield per plant was highly and positively correlated with number of pods per plant, days to final harvest, length of pod and girth of pod. Average pod weight and number of seeds per pod exhibited a negative correlation with pod yield. The negative correlation of these traits on pod yield may be due to their strong negative correlation with number of pods per plant. Genotypic correlation coefficients were partitioned into direct and indirect effects. Number of pods per plant, days to final harvest end girth of pod were the three important components making major contribution to yield,
A selection index was formulated and the genotypes were ranked based on the index score. The genotypes P.T.6 and P.T.25 were found to be best performing ones.
