Rajput M.A. | Sarwar G.
Twenty two lentil genotypes of diverse origin were sown at one site to measure genotypic and phenotypic variances and the association of yield with other traits. Maximum plant height (52.4 cm) was attained by a local check producing high grain yield/plant (7.14 g) and highest number of seeds/plant (216.0). Genotypic and phenotypic variances were very high for number of pods/plant followed by plant height. Maximum heritability was for 100 grain weight (91.0). Genetic advance was very high for number of pods/plant followed by grain yield/plant and 100 grain weight (88.7). Heritability for 100 grain weight, number of pods/plant, and grain yield/plant were accompanied with a high magnitude of genetic advance. Correlation coefficients revealed that seed yield was positively and significantly correlated with number of pods/plant and number of seeds/pod. All other components except for 100 grain weight exerted positive, but non-significant effects on grain yield.
