GENETIC VARIABILITY, HERITABILITY AND GENETIC ADVANCE FOR SOME FRUIT CHARACTERS AND YIELD IN BOTTLE GOURD (LAGENARIA SICERARIA MOLINA. STANDL.) GENOTYPES

M.K. Pandit, B. Mahato, A. Sarkar
Fifteen genotypes of bottle gourd (Lagenaria siceraria Molina. Standl.) were evaluated during the autumn-winter season of 2003-04 at BCKV, West Bengal, India to study the genetic variability, heritability and potential for screening suitable genotypes for future improvement programmes. The genotypes were collected from major growing areas of South-West Bengal. There was considerable variability in all traits except fruit/plant. The moderate GCV and GA in fruit length and fruit weight indicate the probable likelihood of additive gene action. Thus, improving these characters should be effective and rewarding during selection. Promising in-breds for yield/plant were BCBG-7, 17, 19 and 33. The correlation between both genotypes and phenotypes indicate the overriding importance of fruit length and fruit width in determining the average fruit weight, which in turn adequately describes the increase in fruit yield/plant.
