青菜(Brassica campestris ssp. chinensisL.),属十字花科芸苔属,是我国长江流域及南方各省普遍栽培的重要绿叶蔬菜。目前迫切需要培育抗病,抗虫,抗逆和具有优良农艺性状的新品种。用常规育种和细胞工程方法在青菜品种选育方面取得了一定的进展,但是受到种质资源,杂交不亲和性以及耗时长的局限,而遗传工程可提供一个有较大潜力的方法。 Green vegetables (Brassica campestris ssp. Chinensis L.), is a Brassicaceae cruciferous, is China’s Yangtze River valley and the southern provinces of the important cultivation of important green leafy vegetables. There is an urgent need to cultivate new varieties with disease resistance, insect resistance, resistance and agronomic traits. Some progress has been made in selecting and breeding vegetables with the methods of conventional breeding and cell engineering, but germplasm resources, hybridization incompatibility and time-consuming limitations have been achieved. However, genetic engineering can provide a method with great potential.
