ABSTRACT

The investigation entitled “Genetic analysis of yield and its attributes in F3 generation of 5 X 5 half diallel set in bottlegourd (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. Number of seeds per fruit recorded the highest values for genotypic variance (3689.70) and phenotypic variance (3941.20). The characters like fruit length (99.70), days to first female flower opening (98.40), number of branches per vine (98.10) showed high heritability values. Vine length (60.42) and number of branches per vine (38.01) recorded highest values for genetic advance as per cent of mean offering greater scope for selection.Correlation analysis revealed that number of branches per vine (0.684**), number of fruits per vine(0.898**), fruit length(0.803**), fruit girth(0.588*), number of seeds per fruit(0.539*) showed strong positive correlation with yield and among themselves. Therefore these characters could be used as indices for selection of genotypes with high yielding potential.

Key words: Bottlegourd, Genetic analysis, Correlation, Fruits
