Correlation and path-coefficient studies in pointed gourd (Trichosanthes dioica Roxb.)

摘要

Correlation and path-coefficient studies with 16 divergent types of pointed gourd indicated that fruit weight, fruit diameter and number of primary branches/plant were positively and significantly correlated with yield/plant at genotypic and phenotypic levels. The path analysis revealed that fruit volume followed by fruit weight and fruit diameter have maximum positive direct effects on yield. The indirect effects of all the components through fruit volume were relatively high in magnitude irrespective of direction. Therefore, emphasis should be given on fruit weight followed by fruit diameter, fruit volume and number of primary branches/plant in selecting good genotype for improvement of yield in pointed gourd.
