Trait Expression Studies of Indigenous Joha Rice of Assam Under Organic
Journal of Pharmacognosy and Phytochemistry 2019; 8(3): 4290-4295 E-ISSN: 2278-4136 P-ISSN: 2349-8234 JPP 2019; 8(3): 4290-4295 Trait expression studies of indigenous Joha rice of Received: 07-03-2019 Accepted: 09-04-2019 Assam under organic and inorganic culture Khirud Panging Department of Plant Breeding Khirud Panging, Debojit Sarma, Rumjum Goswami Phukon and and Genetics, Assam Shantanu Das Agricultural University, Jorhat, Assam, India Abstract Debojit Sarma The present investigation was conducted to evaluate 12 indigenous Joha rice genotypes for different yield Department of Plant Breeding characters under inorganic and organic cultures. The materials were characterized during sali season of and Genetics, Assam 2015-16 at the Instruction-cum-Research (ICR), Assam Agricultural University (AAU), Jorhat using Agricultural University, Jorhat, Randomized Block Design (RBD) with three replications. Analysis of variance revealed the existence of Assam, India significant differences among the genotypes for all the traits under both inorganic and organic cultures. Among all the characters, panicle weight, grains/panicle, 1000-grain weight, grain yield/plant, straw Rumjum Goswami Phukon yield/plant and harvest index exhibited moderate to high estimates of the genotypic coefficient of Department of Plant Breeding variation (GCV) and phenotypic coefficient of variation (PCV) were recorded under organic and and Genetics, Assam inorganic culture. Also, high estimates of heritability were recorded for days to first flowering, days to Agricultural University, Jorhat, Assam, India 50% flowering, plant height, grains/panicle, 1000-grain weight, and harvest index. High heritability coupled with high genetic advance was observed only for 1000-grain weight under both the cultures.
