Study on correlation and path analysis of F2 population of cucumber (Cucumis sativus L.)

Abstract

An investigation was conducted to study the correlation and path analysis in 150 F2 population of cross Dharwad x Belgaum Local in cucumber along with parents and check during Kharif, 2019 at ZAHRS, Shivamogga. The results revealed that the correlation coefficient for fruit yield per vine had highly significant (P<0.01) and positive with the number of fruits per vine (0.719), the number of nodes at which the first male flower appear (0.271) and the number of branches per vine (0.256). Fruit yield per vine also exhibited positive and significant (P<0.05) association with fruit length (0.201), number of leaves per vine (0.194), days to last harvest (0.181) and inter nodal length (0.158). The path analysis revealed that maximum direct effect of traits viz., number of fruits per vine, days to first female flower appearance, number of seeds per fruit, number of branches per vine, fruit diameter, fruit length, total soluble solids and total sugars on fruit yield. The superior transgressive segregants were identified which surpassed the limits of check hybrid ‘Chitra’ for a yield and quality attributing traits in the F2 population.
