tailieunhanh - Correlation studies in hybrid rice (Oryza sativa L.)

Four male and three female parents, their twelve hybrids along with three standard checks of rice (Oryza sativa L.) were evaluated during Kharif 2016 to study the nature and extent of correlation among yield and yield attributing characters viz., days to 50 per cent flowering, days to maturity, productive tillers plant-1 , plant height (cm), panicle length (cm), total spikelets panicle-1 , fertile spikelets panicle-1 , spikelet fertility (%), 1000 grain weight (g), grain yield plant-1 (g), straw yield plant-1 (g) and harvest index (%). The results revealed that grain yield plant-1 to be positively and significantly associated with days to 50 per cent flowering (), days to maturity (), productive tillers plant-1 (), panicle length (), total spikelets panicle-1 (), fertile spikelets panicle-1 () and straw yield plant-1 () indicating importance of these traits as selection criteria in yield improvement programmes. | 2019 8 4 1158-1164 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 04 2019 Journal homepage http Original Research Article https Correlation Studies in Hybrid Rice Oryza sativa L. .

Introduction Rice Oryza sativa L. is staple food of more than 60 of Indian population. It accounts for about 43 of total food grain production and 46 of total cereal production in the country. Rice occupies pivotal place in Indian Agriculture. In order to meet the domestic demand of the increasing population the present day production of .
