dc.description.abstractThe present studies entitled "Heterosis and combining ability of okra (Abelnoschus esculentus (L.) Moench) under low hill conditions of Himachal Pradesh" were carried out at the Experimental Research Farm of the Department of Vegetable Science, College of Horticulture and Forestry, Dr YS Parmar University of Horticulture and Forestry, Neri, Hamirpur, Himachal Pradesh during the years 2021 and 2022. The experimental material for the present study comprised of eight parents and F1 population of twenty-eight crosses, developed by crossing these eight diverse okra lines in diallel design (excluding reciprocals). All the parents and their hybrids along with the standard check (Punjab-8) were planted in a Randomized Complete Block Design for their evaluation in Kharif, 2022. The observations were recorded on yield and yield related traits viz., germination period, days to 50 per cent flowering, first fruiting node, internodal length (cm), number of primary branches per plant, pod length (cm), pod diameter (cm), number of locules per pod, number of pods per plant, average pod weight (g), pod yield per plant (g), days to first picking, harvest duration, plant height (cm), number of seeds per pod and 100 seed weight (g). The analysis of variance indicated highly significant diferences among the genotypes for all the traits studied. Experimental results revealed that three lines viz., Pusa Sawani, Pusa A-4 and Parbhani Kranti were found superior on the basis of mean performance and general combining ability studies. Three cross combinations viz., Parbhani Kranti x Punjab-8, Pusa A-4 x Pusa Sawani and Pusa Sawanix Arka Anamika were found best on the basis of mean performance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be tested further. Gene action studies indicated predominance of dominance elfets in goveming most of the traits suggesting exploitation of hybrid vigour and developing hybrids for unprovement of these traits in okra on the basis of present studies.
