Correlation Studies of three different F Population 2in Rice (Oryza sativa L.)

This study was performed to determine the assosiation between seventeen agronomic traits of three Fpopulation viz;Dhanrashi x Wita-12, Dhanrashi x Shyamala and Sahbhagidhan x 2Birsamati in riceat Birsa Agricultural University , Kanke, Ranchi, Jharkand in 2019. Sixteen characters were assessed in this study viz days to flowering, plant height, panicles per plant, panicle length, primary branches per panicle, secondary branches per panicle, spikelets per panicle, grains per panicle, 100 grain weight, total yield per plant, grain yield per plant, unfilled grains per plant, grains per plant, spikelets per plant, grain length and grain breadth. Results showed that all the characters except days to flowering and 100 grain weight were positively and significantly correlated with grain yield per plant and grains per panicle in all F2 populations. grain yield per plant was negatively and less assosiated with grain length and L/B ratio in both Dhanrashi x Wita-12and Sahbhagidhan x Birsamatiwhere as in Dhanrashi x Shyamalagrain yield is negatively associated with only L/B ratio.
