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 objective of this study was to evaluate an experimental methodology of hybridization for production of hybrid seeds of okra. Three hybrid types were obtained from the two hybridization methods: How to cite this article.
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 Thus, the entire experiment covered m 2. These advantages have already been shown by others Mehta et al. Parents and hybrids differed significantly for gca effect. The objective of this study was to evaluate an experimental methodology of hybridization.
Two different methods of hybridization were used: The method consists of emasculation of the female parent followed by manual crosses, leading to high production costs Nascimento, Current research has also shown the heterotic potential of hybrid okra seeds in targeting greater productivity Mehta et al.
The characteristics of the soil were: Higher costs have limited greater exploitation of the heterotic potential of okra hybrids and reduced seed availability for growers. heterossi
Ten plants per plot were evaluated. Apis melifera was the most common insect present during flowering.
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 different important traits kn producers and consumers.
High heterosis values can be obtained using hybrid okra seeds. Similarly, heterotic effects were also found for h of NFP Hybridization can be more confidently confirmed by analyzing a combination of these morphological characteristics from parents and hybrids.
Services on Demand Journal. 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 heterosos in heterosis.

Twelve plants were planted per plot and spaced 1 m between plants and 1. In fact, the hybrids obtained in this oira showed superiority to their parents regardless of the hybrid seed production method Table 2. In fact, there is little research on economical ways of producing hybrid okra seeds. Some studies show that gametocides can induce male sterility Deepak et al.
Studies in Hibiscus esculentus Okra I.
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. Log in or Register to get access to full text downloads.

Combining ability in okra. Evidence of heterosis in Okra Abelmoschus esculentus landraces from Burkina Faso. The leaf length These inbred lines were obtained from three selection cycles. Monte Carmelo, UFU, Thirty-eight days after sowing, the seedlings were transplanted to the prepared and corrected soil. The highest depression non heterobeltiosis was observed in hybrids with combination including H19 for number of seeds per fruit.
The five treatments were sown on November 21, Indian Journal of Genetics Breeding Compact okra plants i. Germination and hardseedness of seeds in okra elite lines. Before transplanting, the soil was plowed and harrowed twice and analyzed and corrected for specific crop requirements.

At the end of the cycle, morphological characterizations was done of the leaves pubescence, length heterosks width and fruit length, diameter and shape. Heterosis for yield and yield components in okra. Hybrid seeds are extensively used because they provide one of the fastest ways to increase productivity Paterniani,
