CORRELATION AND PATH ANALYSES FOR YIELD AND BIOCHEMICAL CHARACTERS IN SNAPMELON (Cucumis melo var. momordica)

摘要

Correlation and path analyses were carried out for growth, yield, and fruit quality traits in 30 snapmelon genotypes. Yield per plant was positively and significantly correlated with fruit weight, vine length, flesh thickness, fruit length, frait diameter, first female flower node number, length of fruit cavity, ascorbic acid, and maturity period. Path analysis revealed that vine length, non-reducing sugars, and total carotenoids had high direct effect on yield per plant. Hence, direct selection forvine length, non-reducing sugars, and total carotenoids is suggested for yield improvement in snapmelon.
