Abstract
Heterosis of growth characters and earliness in snakegourd was worked out in a 13 x 13
analysis. Heterobeltiosis and standard heterosis were found for main vine length, primary branches
per plant, days to first male flower anthesis, days to first female flower opening, fruiting nodes on
main vine, days to fruit maturity and days to first f r u i t picking maturity. Days to first female flower
opening showed high heterobeltiosis in parental combinationsTA 102xTA 41, TA 77xTA 41 and
TA87xTA30. The crosses TA 77 xTA 55, TA 89 xTA 19,TA89xTA 102andTA77xTA 99 were
highly heterobelliotic for days to first fruit pickig maturity and in crosses TA 100 x TA 82, TA 77 x
TA 99, TA 77 x TA 41 and TA 30 x TA 99, standard helerosis was high for this trait.
