dc.description.abstractABSTRACT The present investigations entitled “Progeny Evaluation of Open Pollinated Seedling Seed Orchard of Grewia optiva Drummond” were carried out in the Research field and Laboratory of the Department of Tree Improvement and Genetic Resources, College of Forestry, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the year 2013-2015, to evaluate various seed and germination parameters, morphometric and fodder quality parameters of 20 best families, which were only in seed bearing stage. The percentage of these proximate fodder analysis viz. crude protein, crude fiber, ash content, ether extract, and nitrogen free extract ranged from 17.35-20.99 per cent, 17.00-21.51 per cent, 10.42-21.50 per cent, 4.21-5.99 per cent and 40.41-50.24 per cent respectively. For seed parameters families SO-6 (Amberkothi), KA-3 (Varal), HA-1(Bharari), KA-2 (Bhalun) excelled as the best one. Genotype I of family KA-3 (Varal) and Genotye I of family SO-12(Kasholi) were found to be best within family. For germination traits families, CH-2 (Shahu), KA-3 (Varal), SO-10 (Jaunaji), HA-2 (Patta Balakhar) exhibited outstanding performance. Genotype I, Genotype II, Genotype III of family HA-2 (Patta Balakhar) were found best. Progenies of family KA-3 (Varal), CH-2 (Shahu), and CH-5 (Rajpura) were found to be best among family and Genotype I of family CH-2 (Shahu), Genotype III of family KA-3 (Varal), Genotype II of family CH-5 (Rajpura) was showed maximum results within family for morphometric parameters. Fodder parameters of the 20 families, S0-6 (Amberkhothi), KA-3 (Varal) and KA-1 (Dharamshala) excelled as the best ones. Genotype II of family KA-1 (Dharamshala), Genotype I of KA-2 (Bhalun), Genotype II of family MA-2 (Bachhwan) were found to be best within family. For mineral nutrients parameter, families S0-2 (Nauni), KA-3 (Varal), KA-2 (Bhalun) and SO-10 (Jaunaji) exhibited outstanding performance. Genotype I of family KA-3 (Varal), Genotype II of family HA-1 (Bharari), Genotype I of family SO-2 (Nauni) were found to be better within family. Families KA-3 (Varal), CH-2 (Shahu), HA-2 (Patta Bhalaker), KA-2 (Bhalun) and SO-10 (Jaunaji) are best families for further breeding program and better for all the above mention trais. Variability estimates, genetic parameters, correlation studies exhibited high variability among all the families. Higher variability estimates were aided by high heritability, which implied that the variations noticed in foliar nutrients in Grewia optiva were genetically controlled, and thus selection of the family for the desired contents may prove to be of immense value for genetic improvement. Correlation studies showed many significant positive and negative values between the different characteristics. Variability studies suggested that variation can be exploited for any breeding programme of Grewia optiva on the basis of its important characteristics to obtain heterotic vigour through hybridization. Improvement in the fodder quality and production of higher quality planting stock is the need of the hour, which can be fulfilled through selection and breeding programmes.en_US
