Heterosis for fruit yield and its component traits in ridge gourd (Luffa acutangula (Roxb.) L.)

Kiran Jadav and Sapovadiya MH
Twenty-one crosses of ridge gourd in a Line x Tester set involving 10 parents were evaluated in RBD design to study heterosis for fruit yield and its components. The hybrids exhibited marked heterosis over better parent and standard check for various characters. Significant estimates of positive heterobeltiosis and standard heterosis were observed in 10 and 9 cross combinations, respectively for fruit yield per vine and its attributing traits. The range of heterobeltiosis was varied from -24.22 to 36.69%, while the standard heterosis ranged from -17.23 to 26.55% for fruit yield per vine. The cross JRG-13-04 x Jaipur Long (26.55%) recorded the highest standard heterosis for fruit yield per vine followed by JRG-13-04 x Arka Sujat (17.23%), JRG-13-04 x Pusa Nasdar (17.11%), JRG-13-02 x Jaipur Long (16.43%) and JRG-13-06 x Jaipur Long (15.93%). These crosses also recorded significant standard heterosis for length of main vine, number of primary branches per vine, length of fruit and girth of fruit. The results thus, showed that the heterosis for fruit yield per vine was associated with heterosis for its component characters.
