Selection of promising rapeseed mutants on the basis of morphology and yield attributes

Abstract

The experiment was conducted to find out the best rapeseed mutants by observing their morphology and yield attributes. Seven mutant lines (RL-11, RL-12, RL-13, RL-14, RL-15, RL-16 and RL-17) with two checks (Binasarisha-9 and BARI Sharisha-14) were evaluated in this experiment. The experiment was conducted in RCBD design with three replications. High level of genetic diversity was observed among the mutant lines and the check varieties. Among the mutants RL-12, RL-14 and RL-17 proved their performance better in terms of morphology and yield attributes. These three mutant lines showed the highest yield and other yield attributes performance over the two check varieties. From this study it was revealed that these three mutants can be further used in genetic improvement of rapeseed.
