Selection of promising rapeseed mutants through multi-location trials

摘要

Significant variations were observed for most of the characters among the three promising M 5 rapeseed mutants. Mutant RM-025 produced the highest seed yield of 1945 kg/ha followed by RM-005 (1892 kg/ha) and had 11.6 and 8.5% higher seed yield, respectively than the control variety. Under farmers' management, on an average, mutant RM-025 and RM-005 produced 1824 and 1725 kg/ha with 11.3% and 5.2% higher seed yield, respectively than the control variety. These two mutants also had higher number of primary branches and siliquae/plant, and 1000-seed weight and required shorter maturity period than the control variety under both management practices.
