Abstract

The experiment was conducted in experimental Farm, Sher-e-Bangla Agricultural University, Bangladesh from July to December 2011 to study the variability of advanced lines of fine rice with correlation and path co-efficient of yield and yield contributing characters. Seven newly developed lines viz. S-1, S-2, S-5, AL-33(II), AL-36, AL-42(II), AL-44(I) and Chinigura. Grain yield/plant of newly developed advanced fine rice lines and check showed positive association in respect of number of effective tillers/hill (0.308), number of filled spikelets/panicle (0.110) and weight of 1000-grains (0.109), whereas significant negative association with panicle length (-0.609), number of unfilled spikelets/panicle (-0.542) and non significant negative association with plant height (-0.136) and number of ineffective tillers/hill (-0.304). Path analysis revealed that plant height had positive direct effect (0.154), number of effective tillers/hill had positive direct effect (0.065), number of ineffective tillers/hill had negative direct effect (-0.114), panicle length had positive direct effect (0.163), number of filled spikelets/panicle had positive direct effect (0.285), number of unfilled spikelets/panicle had negative direct effect (-0.154), weight of 1000-grains had positive direct effect (0.234) on grain yield/plant.
