M8 rapeseed (Brassica napus L.) mutants: evaluation for earliness with higher seed yield

An experiment was conducted with four rapeseed mutants, their mother variety Binasarisha-4 and early maturing variety Tori-7 during November 2012 to February 2013 at four different rapeseed growing areas of Bangladesh to study their agronomic performances and to select early maturing and high yieldi...
