Gene Effects for Fruit Yield and Its Component Traits in Cucumber (Cucumis sativus L.)

Generation mean analysis in cucumber is carried out to study gene effects for fruit yield and its component traits (number of branches per vine, sex ratio, number of fruits per vine, fruit length, fruit width, average fruit weight and fruit yield per vine) using three crosses viz., ACS12-29 x Belgaum Local, ACS12-31 x B19, ACS12-51 x Poinsett, F1, F2, BC1 and BC2 generation in Rabi season at Kittur Rani Channamma College of Horticulture, Arabhavi, Belagavi district (Karnataka), India. Results indicated that additive gene effect was found significant in all three crosses for sex ratio (M: F), number of fruits per vine, average fruit weight, fruit length and fruit width. In crosses ACS12-31 x B19 and ACS12-51 x Poinsett additive gene effect was predominant for fruit yield per vine and fruit yield per hectare. In ACS12-29 x Belgaum Local and ACS12-51 x Poinsett dominant gene effect was predominant for sex ratio, number of fruits per vine, fruit yield per hectare, fruit yield per vine and pericarp thickness. Additive x dominance gene action found predominant in crosses ACS12-29 x Belgaum Local and ACS12-51 x Poinsett for average fruit weight and in cross ACS12-31 x B19 for number of fruits per vine.
