Abstract:

Studies on heterosis in cucumber (Cucumis sativus L.) was undertaken at ZAHRS, Navule, Shivamogga district, Karnataka during kharif and rabi seasons of year 2016-17. A total of 27 crosses were developed by crossing with nine lines with each of three testers. All the crosses were evaluated along with the parents in randomized block design with two replications. The hybrid Pebkamal × Haveri Local reported the significant negative heterobeltiosis for days to first female flower appearance, node at which first male and female flower appear. The hybrids US-640 × Haveri Local exhibited the significant negative heterosis for days to first harvest over both checks. The cross NCU-1287 × Belgum Local exhibited the significant negative heterobeltiosis (-10.64%) as well as standard heterosis (-8.70%) over the check Poinsette. All the crosses made DWD and Himangi as female parent exhibit the desirable significant positive heterosis for days to last harvest.
