Genetic Variability, Heritability and Path Analysis in Snake Gourd (Trichosanthes anguina L.)

M.A. Rahman, M.D. Hossain, M.S. Islam, D.K. Biswas and M. Ahiduzzaman    

Abstract: Genetic variability, heritability and path coefficient analysis were studied in 24 genotypes of snake gourd. The genotypic coefficient of variation was high for fruit yield, number of fruits per plant, fruit length, stem length and flesh thickness. High to moderate heritability as well as genetic advances were estimated in fruit yield, number of fruits per plant, fruit length, stem length, flesh thickness and average fruit weight. Correlation studies revealed that fruit yield had significant positive correlation with number of fruits per plant, fruit length and stem length. The highest direct positive effect were recorded for number of fruits per plant. For selecting high yielding genotypes emphasis should be given on number of fruits per plant, stem length, fruit length and average fruit weight.
