Abstract: Genetic variability, heritability and correlation studies in 20 genotypes of bitter gourd (Momordica charantia L.). The experiment carried out following randomized block design with three replications, results indicated on the basis of mean performance of 20 genotypes of bitter gourd, Genotype Co-1 (1.61 kg) and Susi Long (1.55 kg) exhibited high fruit yield per plant. On the basis of Analysis of variance significant difference was recorded for all the quantitative and qualitative traits indicating presence of large amount of variability in the genotypes. The genotypic and phenotypic coefficient variation for fruit length (78.19& 78.29) indicating the presence of high amount of variation and role of environment on the expression of these traits. The highest heritability estimate was observed for characters viz high for, Fruit yield/ha (quintal), Fruit length (cm), Fruit yield/plant (kg), Number of fruits/plant, Fruit width (cm), Seed germination %, Node number to which first female flower appear and Fruit specific gravity(cc). Genotypic correlation coefficient analysis revealed that fruit yield per plant (kg) showed positive and high significant association with Fruit yield/ha (0.999), Fruit yield/plant had positive and non-significant association with Fruit specific gravity (0.241) and TSS (0.087). Phenotypic correlation coefficient analysis revealed that fruit yield per plant (kg) showed positive and high significant association with fruit yield per ha (1.000), Fruit yield/plant had positive and non-significant association with specific gravity (0.210).
