Studies on heterosis for fruit yield and quality attributing characters in in okra [Abelmoschus esculentus (L.) Moench]

Abstract

The present investigation was conducted on heterosis for fruit yield quality attributing characters in okra. Fifteen F1 hybrids were generated by half diallel (excluding reciprocals) mating design. These F1 hybrids along with six parents were evaluated in Randomized Block Design with three replications during late Rabi season of 2018 at three locations HRS, Lam; KVK, V.R.Gudem and KVK, Vonipenta, Andhra Pradesh. Observations were recorded for five randomly selected and tagged plants from each treatment for fruit yield and quality attributing characters viz., number of fruits per plant, fruit length (cm), fruit girth (cm), fruit weight (g), number of seeds per fruit, test weight (g/100), fruit yield per plant (g), fruit yield per hectare (t), fibre content (%), ascorbic acid content (mg/100g) and shelf life (days). The values of F1 hybrids averaged over three replications were used for estimating heterosis and pooled data was obtained. The top five heterotic cross combinations viz., 440-10-1 x HRB-9-2, VRO-6 x HRB-9-2, TCR-1674 x HRB-9-2, VRO-6 x JPM-20-16-39 and VRO-3 x HRB-9-2 were identified as stable with desirable heterosis for fruit yield and other important traits.

Estimation of Combining Ability for Flowering and Yield Attributes in Bhendi (Abelmoschus esculentus (L.) Moench)

“…The parent with best general combining ability effect for number of immature seeds per fruit was G5. This is in accordance with the study carried by Vani et al [10], Arvind et al [11], Kalaiselvan and Anuja [12] and Rajani et al [13].…”

“…The following five hybrids viz., G3 x G5 (147.81), G1 x G7 (92.93), G2 x G6 (84.30), G5 x G6 (69.79) and G1 x G4 (41.48) showed the significant sca effect for fruit yield per plant. These results were consonance with the results of Suganthi et al [14], Arvind et al [11], Narkhede et al [15] and Rajani et al [13].…”

Analysis of Heterotic Potential for Earliness, Yield and its Attributing Traits in Okra (Abelmoschus esculentus L. Moench)

“…Phule Vimukta×GAO-5 exhibited both better parent and standard heterosis for this trait. Similar results found by Zate et al (2021) andRajani et al (2021).…”

Study of heritability parameter in hybrids of okra (Abelmoschus esculentus (L.) Moench)

“…Immature tender fresh and green pods are consumed as vegetable. Often the extract obtained from the fruit is added to different recipes like soups, stews and sauces to increase the consistency of it (Hadiya et al, 2018) [10] . The immature pods are used in making pickle, stem and root mucilage in jaggery preparation and crude fibre from mature fruits and stem in paper industry.…”
