Abstract:
The study of heterosis would help in selection of heterotic crosses for commercial exploitation of F1 hybrids in okra [Abelmoschus esculentus (L.) Moench] to achieve improvement in production and productivity. Forty-five F1s were developed by crossing 10 elite lines of okra in half diallel fashion during kharif-2017. All 45 F1s along with their 10 parents and one standard check (GJOH 4) were evaluated in a randomized complete block design with three replicates during kharif (July to October) 2018. The significance of mean squares due to genotypes revealed the presence of considerable genetic variability among the material studied for almost yield and all yield attributes. The heterosis for fruit yield per plant was ranged from -21.85 (AOL 13-144 × Phule Prajatika) to 37.09 per cent (GAO 5 × Kashi Kranti) over batter parent and -9.45 (AOL 13-144 × JF 108-02) to 75.51 (GAO 5 × Kashi Kranti) per cent for standard check. For number of fruits per plant hybrids GAO 5 × Kashi Kranti (28.26%) followed by AOL 12-59 × JF 5 (25.88%) and Phule Prajatika × JF 5 (19.32%) depicted higer heterobeltiosis, while the hybrids AOL 13-144 × VRO 6 (34.20%), JF 5 × JF 108-02 (31.97%), GAO 5 × Kashi Kranti and Phule prajatika × JF 108-02 (31.60%) exhibited higher heterosis over standard check. The superior crosses identified through heterosis analysis were GAO 5 × Kashi Kranti, Phule Prajatika × Red One Long and Phule Prajatika × JF 5 as these crosses had high per se performance as well significant and higher estimates of standard heterosis for fruit yield per plant and yield attributing other characters.
