 ABSTRACT

The investigation entitled “Genetic analysis of yield and its attributes in F3 generation of   5 X 5 half diallel set in bottle gourd (Lagenaria  siceraria (Molina) standley)” was carried out with the objective to identify superior parents and F3 cross combinations and to propose a viable and effective breeding strategy for yield improvement in bottle gourd in a randomized block design with three replications during rabi at horticultural garden, S.V. Agricultural college, Tirupati. The experimental material consisted of five parents viz., Arka Bahar (AB), Pusa Summer Prolific Long (PSPL), Pratik, IC-92330 and Tirupati-local and their ten F3 crosses derived from 5X5 half diallel set. The  analysis of variance for combining ability revealed that both gca and sca  effects were significant for all the characters except hundred seed weight. Estimates of components of variances revealed that the variance due to sca was greater than the variance due to gca indicating the preponderance of non additive gene action for all the twelve characters studied. The estimates of gca effects indicated that IC-92330 was the best general combiner  for yield per vine (0.23**). The  estimates of  sca effects indicated that AB X IC-92330 was the best specific F3 cross for number of branches per vine (3.40**), number of fruits per vine (0.54**), fruit weight(0.33**),fruit length (5.48**), fruit girth (1.02**), yield per vine (1.29**)  and could be of promising for further yield improvement in bottle gourd through selective diallel mating programme.

Key words: Bottle gourd, Analysis of variance, Combining ability analysis, Yield.
