Exploitation of hybrid vigour for yield and quality parameters in okra [Abelmoschus esculentus (L.) Moench] through half diallel analysis
Author(s): Shwetha A, Mulge R and Khot R
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 quality parameters. The magnitude of heterosis varied in all the crosses for the characters studied. Maximum positive heterosis for yield per plant and yield per hectare was observed in the cross KO1601 x KO1605 over better parent and the cross KO1606 x KO1608 over the best parent and the commercial checks (Arka Anamika and MHY-10) followed by KO1602 x KO1608 and KO1603 x KO1606. For number of fruits per plant, the crosses KO1601 x KO1604 and KO1607 x KO1608 exhibited maximum heterobeltiosis and standard heterosis respectively. Magnitude of heterosis over the commercial checks was maximum in the cross KO1603 x KO1606 for average fruit weight and the cross KO1601 x KO1606 exhibited maximum positive heterosis over better parent and the commercial checks for number of seeds per fruit. High estimates of heterosis obtain in hybrid combinations revealed considerable genetic divergence among the parental lines.
