Abstract
The present study highlights about Genetic variability, heritability and genetic advance in bottle gourd [Lagenaria siceraria (Mol.) Standl.] genotypes. Experimental material for the study consisted of 25 genotypes including a check (Narendra Kamna). Observations were recorded on fifteen quantitative characters. The analysis of variance for the design of experiment indicated highly significant differences among the genotypes for fourteen characters. Based on mean performance of fruit yield and yield components genotypes, PBR-3 followed by Narendra Pooja, BG-131-1 and Pant Lauki were found as significant and most promising genotypes. High phenotypic along with genotypic coefficients of variation was observed in case of fruit yield per ha, fruit yield per plant, average fruit weight, fruit length indicating possibility of obtaining higher selection response in respect of these traits. High heritability coupled with genetic advance was shown in the characters like fruit yield per plant, average fruit weight and fruit length.
