Plant height of rapeseed plays an important role in yield and resistance,especially the lodging resistance.The yield can be increased through increasing harvest index and resistance,which can be realized by reducing the plant height properly.The dwarf inbred line,‘74-1002',with traits of early maturity,multiple valid branches and lodging resistance,is a suitable material for rapeseed breeding.In this study,‘74-1002'was served as male parent and‘HN92',another inbred line of Brassica napus L.with high plant h...
