Heterosis and combining ability for yield and its related traits in ridge gourd [Luffa acutangula (L.)Roxb.]

Line × Tester analysis involving three lines and four testers was carried out in ridge gourd [Luffa acutangula (Roxb.) L.]. Significant variation was noticed in the mean performance of the parents and hybrids for all the characters studied except for vine length and fruit girth. The results from GCA...
