Abstract

Eight collections of bittergourd ( Momordica- charantia) were studied for genetic variability and degrees of association of yield and yield components. Of eight characters studied, genotypic and phenotypic coefficient of variation and genetic advance in percentage of mean were the highest for leaf area followed by seeds per fruit, weight per fruit, yield per plant and the lowest for days to female flower. The highest heritability was found in seeds per fruit followed by leaf area, fruits per plant, weight per fruit and the lowest in fruit breadth. High heritability along with high genetic advance was observed in seeds per fruit, leaf area and weight per fruit. The correlations at genotypic level were higher than their corresponding phenotypic level. Yield per plant was highly positively correlated with weight per fruit and fruit length. These two characters were also positively significantly correlated with the leaf area.
