Abstract
Growth performance, yield components and total grain yield of a rice mutant lines were evaluated againest two popular rice varieties on farm experiments within five different upazila of Mymensingh region to find out the better cultivar on the besis of yield and duration. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The study was conducted for two consecutive season that ensure the stability of the mutant line. The results revealed that the cultivar RM(2)-40-©-4-2-8 was recorded highest effective tiller and maximum filled grain in most of the location. Among the all cultivar RM(2)-40-©-4-2-8 was recorded maximum grain yield in most of the location for two consecutive year which was statistically significant from other cultivar.
