Abstract

Line x Tester study was conducted in bottle gourd during
summer and kharif 2008 at Zonal Agriculture Research
Station, Chhindwara, centre of Jawaharlal Nehru Krishi
Vishwa Vidyalaya, Jabalpur. It is observed that the estimates
of specific combining ability variances were higher in
magnitude than general combining ability variances for all
the characters, indicated that the predominance of nonadditive
type of gene action. The estimate of general
combining ability effects showed that JBG 9 was a good
general combiner for all the characters except for days to
appearance of first male flower, number of female flowers
per plant, fruit setting percent. Estimates of specific
combining ability effects revealed that five crossed viz., JBG4
x T1 (Pusa Naveen), JBG6 x T1 (Pusa Naveen), JBG9 x T1
(Pusa Naveen), JBG5 x T3 (PSPL) and JBG11 x T3 (PSPL)
were the best specific combiners for yield and major yield
components.Line x Tester study was conducted in bottle gourd during summer and kharif 2008 at Zonal Agriculture Research Station, Chhindwara, centre of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur.
