Combining ability analysis in ridge gourd [Luffa acutangula (Roxb.) L.] for yield attributing traits
Author(s): Deepika Sharma and AK Soni
Abstract: Combining ability studies carried out through half-diallel method (excluding reciprocals) using eight parents in ridge gourd for yield and yield components. F1’s and parents were evaluated under two season i.e. rainy 2016 and summer 2017. This analysis revealed that GCA and SCA variance were significant for all the indicating the importance of both additive and non additive genetic control of all the characters studied. The GCA variances lower than the SCA variances indicating the predominance of non-additive gene effects. Two parents viz., Pusa Nasdar and Pusa Nutan were found to be good general combiners for yield and yield components. The crosses Swarna Manjari X Konkan Harita and Pusa Nutan X Arka Sumeet found to be good for most of the characters whereas, in respect to fruit weight and total fruit yield per vine, good specific combiner was identified as Pusa Nutan X Konkan Harita, Pusa Nasdar X Pusa Nutan and Pusa Nutan X Arka Sumeet. The crosses exhibiting high SCA effect involved either good x poor general combiners for majority of characters indicating the presence of additive x dominance type of gene interactions.
