摘　　要：为筛选适合上海冬闲田种植的油菜品种,基于原有审定品种,选择生物学产量较高的11个油菜品种进行评价。结果表明:‘沪油17’和‘沪油21’的植株高度中等(165—170 cm),分枝部位较低(50 cm左右),主花序较长(62—65 cm),有效分枝数多(14个以上),二者的鲜草产量均超过了34500 kg∕hm^(2),分别比对照增产14.60%和11.34%。经鉴定,‘沪油17’和‘沪油21’为耐低温型品种,推荐‘沪油17’和‘沪油21’为上海冬闲田绿肥种植品种。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 34500 kg∕hm^(2),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.
