烟草花叶病毒(TMV)是番茄的一种主要病害,迄今药剂防治尚不能见效。国外四十年代已开始从选育抗病品种入手,从研究的进展来看,利用具有烟草花叶病毒抗源基因的品种或育种材料收效较快。我所于1975～1979年,以美国品种ManapalTm_2—nv(编号201,以下简称201)为亲本,配制正反交杂种组合(简称201F_1)40余个。结果是:早×201适合覆盖和露地早熟栽培;524×201、弗×201、强×201等适合春季露地栽培;402×201、特
Tobacco mosaic virus (TMV) is a major tomato disease, so far the drug control is still not effective. In the forties of the world, we started with the selection of resistant varieties. According to the progress of the research, the use of varieties or breeding materials that have the anti-tobacco mosaic virus resistance gene is more effective. From 1975 to 1979, we used more than 40 reciprocal hybrid combinations (referred to as 201F_1) from the American variety ManapalTm_2-nv (No. 201, hereinafter referred to as 201) as our parents. The results are: early × 201 suitable for covering and open-field cultivation; 524 × 201, Fu × 201, strong × 201 and other suitable for spring open field cultivation; 402 × 201, special
