Studies on heritability and genetic advance for growth, yield and quality traits in bottle gourd [Lagenaria siceraria (Mol.) Standl.]

The investigation carried out during warm season of 2017-18 and 2018-19 at main experimental station vegetable science, Kumarganj, Ayodhya. The experiment laid out in Randomized Block design (RBD) with 55 treatment and replicate thrice. Observations were recorded for days to first staminate and pistillate flower anthesis, node number to first staminate and pistillate flower appearance, primary branches per plant, vine length (m), fruit circumference (cm), fruit weight (kg), and fruit yield per plant (kg). High heritability for most of the traits along with high genetic advance in per cent of mean were number of primary branches per plant, fruit length, fruit weight, and number of fruits per plant while High heritability along with moderate genetic advance were found for days to first staminate and pistillate flower anthesis, node number to first staminate and pistillate flower appearance, vine length, fruit circumference, fruit yield per plant over pooled. Thus, there exist a great scope of response to selection through improvement of these traits in bottle gourd.
