HETEROSIS IN OKRA PDF

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.

The new hybridization method IHM consisted of ora the female flowers and then allowing pollination to occur via insects that were naturally present at the experiment site. Not only did the C4, C5 and C6 contrasts show the superiority of these three hybrids, regardless of seed hybridization method, they also demonstrated the heterosis of the hybrids and the use of new method of producing hybrid okra seeds. These advantages have already been shown by others Mehta et al.

Significant differences in production per plant PP and number of fruits per plant jn observed in the different hybrids regardless of hybridization method THM and IHM Table 2. The leaf length The number of steps was reduced in this process by eliminating the need to protect the emasculated female flowers or collect male flowers. Thus, the entire experiment covered m 2.

Chilean Journal of Agricultural Research Two different methods of hybridization were used: In fact, there is little research on economical ways of producing hybrid okra seeds. Indian Journal Agriculcural Sciences Okra Abelmoschus esculentus belongs to the Malvaceae family and originates from Africa.

High heterosis values can be obtained using hybrid okra seeds. Acessado em 23 de janeiro de Heterosis resulting from the incomplete emasculation followed by natural insect pollination was similar to that from the traditional hybrid method, being a viable alternative for the production of hybrid okra seeds without losses in heterosis.

Germination and hardseedness of seeds in okra elite lines. Similarly, heterotic effects were also found for h of NFP We used the expression proposed by Fehr to evaluate the heterosis. Some reports show that the number of fruits per plant is related to the action of other types of gene actions such as epistatic additive x additive that allow transgressive segregation Kulkarni et al.

This is an open-access article distributed under the terms of the Creative Commons Attribution License. Thus, the traditional and more labor intensive okra seed hybridization method THM can be reliably replaced by the less labor intensive method IHM without any loss in heterosis.

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 characteristics of the soil were: This new method was adopted because of the results obtained by Malerbo-Souza et al.

The branches were counted after the last harvest of the experiment. Featuring journals from 32 Countries: The plants were spaced 1. Traditional hybridization method THM consisted of emasculating the female parent flowers to expose the flower stigma before anthesis and eliminate the presence of pollen.

The fruits were harvested every three days from February heteroais, until June 27,totalling 41 harvests.

Revista da Agricultura Evidence of heterosis in Okra Abelmoschus esculentus landraces from Burkina Faso. Production per plant Polystyrene trays cells were filled with a commercial coconut fiber substrate and used to produce seedlings for each line.

Heterosis in okra hybrids obtained by hybridization of two methods: traditional and experimental

Study on heterosis and combining ability for earliness and yield parameters in okra Abelmoschus esculentus L. Significant differences were not observed for the leaf pubescence, but ojra leaf length of the UFU-QBD and UFU-QBG parents, which were directly involved in obtaining the hybrids, were significantly different Heterosis for yield and yield components in okra.

Monte Carmelo, UFU, After extraction, the seeds were placed in pre-labeled Kraft paper bags and stored.
