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.

Evidence of heterosis in Okra Abelmoschus esculentus landraces from Burkina Faso.

Novo manual de olericultura. Germination and hardseedness of seeds in okra elite lines.

Thus, the entire experiment covered m 2. Despite the superior genetic potential of hybrid okra seeds, seed production remains an obstacle.

At the end of the cycle, morphological characterizations pkra done of the leaves pubescence, length and width and fruit length, diameter and shape. After pollination, the female flowers were protected with Kraft paper to avoid contamination from insect pollination Nascimento, The five treatments were sown on November 21, Significant differences were not observed for the leaf pubescence, but the leaf length of the UFU-QBD and UFU-QBG parents, which were directly involved in obtaining the hybrids, were significantly different Studies in Hibiscus esculentus Okra I.


High heterosis values can be obtained using hybrid okra seeds.

Featuring journals from 32 Countries: Bangladesh Journal of Agricultural Research The new hybridization method IHM consisted of emasculating the female flowers and then allowing pollination ih occur via insects that were naturally present at the experiment site. Production per plant Similarly, heterotic effects were also found for h of NFP The regional climate is humid temperate with hot summers and dry winters.

The fruits were harvested every three days from February 2, until June 27,totalling 41 harvests. Chilean Journal of Agricultural Research Significant differences in production per plant PP and number of fruits per plant were observed heterois the different hybrids regardless of hybridization method THM and IHM Table 2.

In fact, there is little research on economical ways of producing hybrid okra seeds. O,ra reports show that the number of fruits per plant is related to the action of other types of gene actions such oka epistatic additive x additive that allow transgressive segregation Kulkarni et al.

The characteristics of the soil were: The objective of this study was okda evaluate an experimental methodology of hybridization for production of hybrid seeds of okra. Overall, the results discussed above indicated the ojra that okra hybrid with UAE 22 has great potentialities of maximizing fruit yield while hybrid H and H have the smallest days of flowering.


These advantages have already been shown by others Mehta et al. How to cite this article. Acessado em 23 de janeiro de The following agronomic characteristics were determined: The Asian Journal of Horticulture 3: Before transplanting, the soil was plowed and harrowed twice and analyzed and corrected for specific crop requirements.

However, despite high heterotic values, it is very difficult to produce hybrid okra heetrosis. Heterobeltiosis and combining ability for earliness in okra Abelmoschus esculentus L.

International Journal of Biological and Chemical Sciences

The plants were spaced 1. The resulting hybrid seeds and their parents were evaluated via an experiment set up in a randomized block design with four repetitions.

Twelve plants were planted per plot and spaced 1 m between plants and 1. Hybridization can be more confidently confirmed by analyzing a combination of these morphological characteristics from parents and hybrids. Heterosis for yield and yield components in okra Abelmoschus esculentus L. Parents and hybrids differed significantly for gca effect.
