Screening of rapeseed varieties suitable for winter fallow cropland in Shanghai
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.
