| Abstract: | Guanchun is a new F1 hybrid of spring Chinese cabbage combined by crossing one self-incompatible line 01S315 and one self-compatible line 01S105. This variety is mid-maturity,resistances to multi-diseases such as tipburn, soft-rot, virus, downmidey, and strong bolting-resistance. The average weight per leafhead is about 2.0 kg. It can be harvested in 60~65d after transplanting. It can yield net vegetable 89.2 t/hm2. This variety has been idenificated and registrated by Shaanxi Province agricultural seed administration station in 2004. |
