In order to screen the rapeseed varieties suitable for winter fallow cropland of Shanghai,11 registered rapeseed varieties with high biological yields were selected.The results showed that'Huyou 17'and'Huyou 21'had moderate plant heights(165-170 cm),low branch parts(50 cm)and long racemes(62-65 cm)and more plant branches(more than 14).The fresh grass yields of'Huyou 17'and'Huyou 21'were exceeded 34 500 kg/hm2,increased more than 14.60％and 11.34％as to the control,respectively.In addition,'Huyou 17'and'Huyou 21'were identified as the low-temperature tolerance type by low temperature germination test.Therefore,we recommend'Huyou 17'and'Huyou 21'as green manure planting varieties for Shanghai winter fallow cropland.
