Variability, heritability genetic advance and correlation coefficients for yield component characters and seed yield in Greengram (Vigna radiate (L.) Wilczek)

Author(s): Pulagampalli Ramachandra and G Roopa Lavanya
Abstract: The present experiment was conducted to evaluate 22 greengram genotypes along with one check (SAMRAT). Analysis of variance showed high significant differences among 22 greengram genotypes for 12 quantitative characters studied. Maximum genotypic and phenotypic variance was recorded for pods/plant and harvest index, Maximum GCV and PCV were recorded for pods per plant, pods per plant. High heritability was recorded for harvest index, pod length, seeds per pod, and primary branches per plant. High heritability coupled with high genetic advance as percent of mean was recorded for harvest index. Correlation coefficient analysis revealed that seed yield/plant exhibited significant and positive correlation both at genotypic and phenotypic levels with seed index, seeds/pod and days to maturity. These characters can be used as selection indices for green gram yield improvement.
