Abstract
The present investigation consisting a set in a fashion of line x tester cross combinations were carried out to investigate the inter characters relationship for fifteen characters in In Rice (Oryza staiva L.). The experiments were conducted during Kharif, 2019-2020at Students Instructional Farm of Department of Genetics & Plant Breeding, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya-224229 (U.P.) days to 50% flowering, day to maturity, plant hright (cm), productive tillers per plant, chlorophyll content, panicle length, flag leaf area (cm), number of spikelets per panicle, spikelets fertility, grains size (L:B ratio), 1000-grain weight (g), biological yield per plant (g), harvest-index (%), protein content and grain yield per plant (g), were studied in the LxT experiment. In this study, grain yield per plant exhibited highly significant and positive association at phenotypic level with harvest index, followed by panicle length and other traits at genotypic and phenotypic correlation analysis. Character harvest index has highest direct effect on seed yield followed by biological yield per plant and some other traits at both genotypic and phenotypic path analysis. Resultant direct selection for these traits would be effective for further yield improvement in given genotype of rice.
