“…The hybrids expressed highest significant negative sca effect was reported on EC 102605 x Arka Anamika (-0.33) for fruit girth. The results are in agreement with More et al, (2017), Satish et al, (2017) and Shwetha et al, (2018).…”

The present experiment on bhendi consisted of 12 parents (9 lines and 3 testers) with their 27 F1 hybrids developed through line x tester mating design with three replications in randomized block design. Parents and hybrids differed significantly for gca and sca effects, respectively. Among the parents, maximum gca effect was found in EC 169329 and Aruna for fruit length, EC 102605 and Arka Anamika for fruit girth, EC 112241 and Arka Anamika for fruit yield per plant, EC 169335 and Aruna for ascorbic acid content, EC 109454 and Arka Anamika for mucilage content. The crosses EC 169331 x Kashi Kranti, EC 102605 x Arka Anamika and EC 169344 x Arka Anamika were found as good specific combiners for fruit length, fruit girth and yield per plant respectively. The hybrids EC 169335 x Aruna and EC 109454 x Arka Anamika exhibited maximum significant positive sca effects for quality traits like ascorbic acid content and mucilage content respectively.

“…Positive heterosis is desirable yield and its attributing traits where out of 35 crosses the trait plant height, 18 crosses exhibited positive significant effect over heterobeltiosis range from 8.48% (GAO-8×VRO-6) to 31.84% (Phule Vimukta×GAO-5) and 12 crosses exhibited positive significant over standard heterosis range from 10.04% (Phule Prajatiti×K-54) to 15.31% (Harita×VRO-6). Similar findings reported were consistent with the results obtained by Shinde et al (2023); Shwetha et al (2021) and Chavan et al (2023). For number of branches only 3 crosses exhibited significant for heterobeltiosis range from 15.21% (Phule Vimukta×GAO-5) to 27.33% (Pusa Savani×K-54) and 14 crosses exhibited positive significant heterosis over standard heterosis range from 14.50% (Punjab Suhanani×Arka Abhay, GO-6×VRO-6) to 24.44% (Phule Prajatiti×VRO-106).…”

The present study was conducted during the late kharif season (July to November, 2023) at the Genetics and Plant Breeding Research Farm, School of Agriculture, Lovely Professional University, Phagwara, Punjab India. This study assessed heterosis in okra (Abelmoschus esculentus L.) for 12 traits, including earliness and fruit yield using Randomized Block Design. Thirty-five F1s were obtained from crossing 7 lines with 5 testers in line×tester method and compared with one commercial check (Punjab-8) to estimate standard heterosis and heterobeltiosis among better parents. Significance of mean square due to genotypes revealed the presence of considerable genetic variability among the material studies for almost all the traits. The best positive heterotic cross over better parent (Heterobeltiosis) and standard check (Punjab 8) for fruit yield plant-1 was Go-6×Arka Abhay (72.32%) and Phule Prajatiti×Arka Abhay (41.63%) respectively. While Punjab Suhanani×GAO-5 (-12.05%) was found as negatively heterotic cross for days to 50% flowering over better parent and GAO-8×Arka Abhay (-13.26%) over standard check respectively. For days to first picking Pusa Savani×VRO-106 (-14.44%) exhibited negatively significant heterosis over better parent and Phule Prajatiti×Arka Abhay (-14.49%) over standard check respectively, that are important to exploit the earliness traits in okra. The hybrid Phule Prajatiti×Arka Abhay, which has a high potential for yield and fruits can be picked earlier which may evaluated further for early kharif season in Punjab.

Due to the increased water shortage and frequent drought in Egypt, it is essential to develop droughttolerant plants. Therefore, five drought tolerance lines of okra were used to develop superior hybrids under drought conditions, using a half-diallel mating design to produce fifteen hybrids. There were significant differences among the hybrids and their parents in mean squares for all studied traits. The hybrids (P 2 XP 6 ), (P 2 XP 3 ), (P 1 XP 2 ) and (P 2 XP 4 ) exhibited the maximum mid-parents (MP) and better parent (BP) heterosis for total yield/plant.The mean squares for general (GCA) and specific combining abilities (SCA) were significant for studied traits, which indicates the importance of additive and non-additive gene actions in the inheritance of the studied traits in okra.The magnitudes of additive genetic variance (σ 2 A) were larger than their corresponding non-additive genetic variance (σ 2 D) for plant height, number of branches per plant, number of days to 50% flowering, pod length and total yield/plant. This revealed the major effect of additive inheritance for these traits.Genetic analysis illustrated that broad sense heritability (h 2 bs %) values were larger than their corresponding heritability in narrow sense(h 2 ns %) for all studied characters.As for the correlations between yield component traits, there were significant and positive genotypic correlation (r g ) among total yield/plant and plant height, average pod weight and number of pods/plant. Overall, these crosses are promising hybrids with high yielding ability, and could be commercially recommended to improve economical traits in okra under drought conditions.
