Abstract:
Seven parental lines of bottle gourd and their 21 F₁ hybrids obtained from half diallel were studied to investigate the extent of heterosis for yield and quality parameters. The experiment laid out in RBD, two replications with spacing 2 m x 1 m during summer season 2020-2021 at experimental Research Farm Department of Horticulture, College of Agriculture Latur. The significant heterosis for F1’s over better parents for the various characters viz., Karjat Local x Amravati Local (number of branches per vine, days required for first female flower, node at which first female flower appeared, days required for first harvest of fruit, average weight of fruit, average length of fruit), Buldhana Local x Amravati Local (Length of vine), Chandrapur Local x Kolhapur Local (average diameter of fruit, rind thickness), Karjat Local x Buldhana Local (yield of fruit per ha), Aurangabad Local x Karjat Local (Vitamin-c). Using parents in these crosses can be used in the future breeding programme for hybrid development.
