HETEROSIS FOR FRUIT YIELD AND ITS COMPONENTS IN OKRA (ABELMOSCHUS ESCULENTUS L. MOENCH)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 18
Abstract
Eight parental lines of okra and their 28 F1 hybrids obtained from half diallel were studied to investigate the extent of heterosis for yield and its attributes. The magnitude of heterosis varied in all the crosses for the characters studied. Maximum positive heterosis for fruit yield per plant over better parent and standard check (JOH 2) was observed to be 62.12 and 44.11 per cent, respectively. The cause of heterosis may be due to its component traits, viz., days to first flowering, nodes per plant, length of inter node, fruit weight and fruits per plant. The best hybrid AOL 09-25 x AOL 09-26 recorded 44.11 per cent heterosis for yield over standard check, may be exploited for commercial cultivation.
