Estimate of genetic variability, heritability and genetic advance in Plum (Prunus salicina L.) cultivars

Studies on correlation coefficient and genetic variability along with heritability were conducted in Plum cultivars. A wide range of variability along with high estimates of genotypic coefficient variability and phenotypic coefficient of variability was noted for plant spread North-South and East-West spread, tree volume, yield and fruit weight. High heritability noted for days taken to maturity, yield, fruit weight, fruit length and fruit diameter, Total soluble solids and acidity. High genetic advance was recorded for days taken to maturity, yield and fruit weight. Genetic gain was found high for plant spread (E-W), yield and fruit weight, which might be assigned to additive gene action.
