In our study, 24 hybrids obtained by diallel cross between ecotypes of okra were subjected to analysis of their combining ability effects and hybrid vigor for. ABSTRACT. High heterosis values can be obtained using hybrid okra seeds. However, despite high heterotic values, it is very difficult to produce hybrid okra. Studies on Heterosis in Okra (Abelmoschus esculentus (L.) Moench) The results revealed that the standard heterosis for fruit yield per plant was maximum in.

After pollination, the female flowers were protected with Kraft paper to avoid contamination from insect pollination Nascimento, The branches were counted after the last harvest of ib experiment. Significant differences in production per plant PP and number of fruits per plant were observed in the different hybrids regardless of hybridization method THM and IHM Table 2.
Heterosis for yield and yield components in okra. A traditional method is currently used in Brazil for large scale production of hybrid okra seeds. Indian Journal of Genetics Breeding Data for each of the agronomic characters were submitted to analysis of variance F test.

This new method was adopted because of the results obtained by Malerbo-Souza et al. Heterobeltiosis and combining ability for earliness in okra Abelmoschus esculentus L.
Originated fruits of hybridization were harvested when they reached physiological maturity and then the seeds were extracted separately according to hybridization method THM and IHM. The Asian Journal of Horticulture 3: In fact, the hybrids obtained in this study showed superiority to their parents regardless of the hybrid seed production method Table 2. Okra Abelmoschus esculentus belongs to the Malvaceae family and originates from Africa.
