Abstract:
The present study was conducted at College of Horticulture, Dr. Y. S. R. Horticultural University, Venkataramannagudem, Andhra Pradesh, India during 2019-2020, to study the combining ability of ten different lines of bottle gourd. They were mated diallel fashion excluding reciprocals and their forty-five crosses were evaluated along with ten parents and two checks in Randomized block design (RBD) for growth, yield and quality attributing characters. Significant differences of analysis of variances due to GCA and SCA were observed for all the characters, it indicates predominance of non additive and additive gene action, that provides ample scope for heterosis breeding or direct selection. Out of the ten parents studied Local Round, Pusa Samridhi, Pant Lauki-3 and Kashi Ganga were found to be good general combiners for quality, yield and quality characters. Based on sca effects, eight cross combinations viz., Pusa Naveen x Arka Bahar, Pusa Naveen x Kashi Ganga, Pusa Naveen x Punjab Bahar, Pusa Samridhi x Pant Lauki-3, Pusa Samridhi x Local Round, Pusa Santhusti x Kashi Ganga, Pant Lauki-3 x Local Round, Pant Lauki-3 x Local Long were identified as promising for fruit yield per vine, fruit length and average fruit weight. The knowledge of combining ability helps in identifying good combiners for hybridization.
