 ABSTRACT

The success of any crop improvement programs depends upon the genetic variability and heritability of desirable traits. Thirty genotypes along with two checks (DC 15 and DCS 47-1) were evaluated for genetic variability and other related parameters in respect of eight quantitative characters during Kharif 2016. Analysis of variance revealed highly significant differences among genotypes for all the characters studied. Considerably high range of variation was observed for characters viz., seed yield, days to fifty per cent flowering, plant height and number of pods per plant. High PCV and GCV values were recorded for the traits seed yield and number of pods per plant. Plant height showed moderate PCV and GCV values whereas, remaining traits exhibited low to moderate PCV and GCV values. High heritability coupled with high GAM was exhibited by seed yield, number of pods per plant and plant height. Characters such as days to fifty percent flowering and days to maturity showed high heritability and low GAM. Moderate heritability with moderate GAM was recorded by number of seeds per pod and hundred seed weight. However, pod length recorded moderate heritability and low GAM.

Key words: Genetic variability, Heritability, Genetic advance, GCV, PCV.
