| Abstract: | Objective] The research aimed to study the suitable planting density of the compact planting variety Qianxing 201.Method] The influences of density on the yield and plant character of Qianxing 201 and Huidan 4 were studied with the field experiment and six levels of planting density.Results] The results showed that the relation between yield and planting density accorded with one-place quadratic.For Qianxing 201 and Huidan 4,it was a significant negative correlation between the 1 000-grain weight and density(P<0.01) and there was a significant negative correlation between ear length,ear rows and density(P<0.05). Conclusion] There was a promising prospect for commercial production of Qianxing 201 in Guizhou province and the 1 400～2 550 m elevation area of Yunnan province. |
