Abstract

An experiment was conducted to evaluate correlation between some traits and yield components of six aromatic rice varieties and also to determine the most effective factors on its yield. The experiment was conducted in a randomized complete block design (RCBD) with 3 replications. Among six variteits Badshabhog was the topmost yielder followed by Kataribhog, Chinigura, and Radhunipagal, Begunbichi and Kalozira. Analysis of variability parameters revealed that the phenotypic coefficients of variation were higher than genotypic coefficient of variation for all the characters studied. The spikelets panicle-1 and 1000-grain weight showed high heritability and effective tillers hill-1 showed low heritability. Yield has positive significant correlation with days to maturity, spikelet length and 1000-grain weight. Negative significant correlation found with plant height and sterility percentage and non-significant correlation with other characters.
