| Abstract: | The data of tillering ability and panicle formation of wheat variety--Wanmai No.19 for several years was statistically analyzed. The result indicated that the index for wheat yield of 6000～7500kg/hm2 should be: 1.65～2.1 million seedlings/hm2, 5.6～6.5 tillers per plant and 9.5～10.5 million panicles/hm2 before Winter, 14.2-19.0 million tillers/hm2, 3.8 panicles per plant and 6.08 million panicles/hm2 in next Spring, which resulted in a coordinational population and high yield. |
