适宜“油蔬两用”的油菜品种筛选

为筛选出适宜湖北地区应用推广的"油蔬两用"油菜品种,对9个"双低"甘蓝型油菜品种摘薹与未摘薹的产量、产值及主要性状进行了比较分析。结果表明,油菜摘薹后菜子产量比未摘薹平均增12.52%,总产值比未摘薹平均增124.08%,初步分析油菜摘薹后二次分枝及每角粒数普遍增加是菜子产量增加的主要原因。供试品种中,中油112菜薹、菜子产量高,菜薹口感甜脆爽口,可作为高产型"油蔬两用"品种推广应用;天下农3号菜薹产量及总产值高,浙油28菜薹口感及主要经济性状表现突出,菜子增产潜力大,二者可以作为"油蔬两用"配套品种。

Screening of Oilseed and Vegetable Dual-use Rape Varieties

In order to choose oilseed and vegetable dual-use rape varieties in Hubei province,the yields,production values and main characters of nine double-low Brassica napus varieties with picking the flower stalk or not were analyzed.The results showed that the average rapeseed yield of the nine rape varieties increased by 12.52% and the average output of them increased by 124.08% by picking the flower stalk.The major factors causing the increasing of rapeseed production were the generally increasing of the second branches and the number of grains per pod after picking the flower stalk.Among the tested varieties,Zhongyou 112 exhibited higher flower stalk and rapeseed yield and its flower stalk tasted sweet and refreshing.Therefore this cultivar could be regarded as appropriate oilseed and vegetable dual-use variety.Tianxianong No.3 was with the higher flower stalk and higher output value,and Zheyou 28 was with outstanding taste,major economic traits,and enormous potential of rapeseed yield.Hence the two varieties could be used as matching varieties for oilseed and vegetable dual-use varieties.
