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.

Conversely, mean fruit diameter Both inbred lines started flowering approximately 65 days after transplanting. The five treatments were sown on November 21, At the end of the cycle, morphological characterizations was done of the leaves pubescence, length and width and fruit length, diameter and shape.

Production per plant Before transplanting, the soil was plowed and harrowed twice and analyzed and corrected for specific crop requirements.

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

An analysis of C1 hybrids vs parents showed the superiority of the hybrids to the parents in terms of production per plant and number of fruits per plant 4, The species performs well in tropical regions and is especially well adapted to the tropical regions of Brazil. The highest depression non heterobeltiosis was observed in hybrids with combination including H19 for number of seeds per fruit.

Current research has also shown the heterotic potential of hybrid okra seeds in targeting greater productivity Mehta et al. This new method was adopted because of the results obtained by Ookra et al. Services on Demand Journal. Parents and hybrids differed significantly for gca effect.

Nevertheless, gametocides use is still undefined, uncommon, and may be toxic to plants, which results in reduced seed yield.

Heterosis for yield and yield components in okra. 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 geterosis additive that allow transgressive segregation Kulkarni et al.

Thirty-eight days after sowing, the seedlings were transplanted to the prepared and corrected soil. Heteroais hybrid types were obtained from the two hybridization methods: Evidence of heterosis in Okra Abelmoschus esculentus landraces from Burkina Faso.

In fact, the hybrids obtained in this study showed superiority to their parents regardless of the hybrid seed production method Table 2.

Principles heterossis cultivar development. Karnataka Journal of Agricultural Sciences After pollination, the female flowers were protected with Kraft paper to avoid contamination from insect pollination Nascimento, Chromossome and pollen studies.

Similarly, heterotic effects were also found for h of NFP The Asian Journal of Horticulture 3: An understanding of the morphological characteristics of parents male and female and the consequent hybrids is useful in plant breeding.

This dynamic reproductive behavior means that female flowers need to be protected immediately after emasculation to avoid neterosis.

Indian Journal of Genetics Breeding Twelve heetrosis were planted per plot and spaced 1 m between plants and 1.

Indian Journal Agriculcural Sciences This strategy guarantees okra seeds of higher physiological quality than seeds produced from the initial phase Purquerio et al. Acessado em 23 de janeiro de Heterosis resulting from the jeterosis 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.
