Abstract: This paper studied yield components of four wheat v arieties under the different planting-method.The result showed that there was n o significant difference between 15 cm equidistant row spacing and 20 cm-10 cm wide-narrow row.A significant difference among varieties under the low density andhigh density was existed.Dynamic change of leaf area index was different si gnificantly among varieties.From flowering to milk ripe stage,ithas descend tre nd,only 93zhong6has ascend trend ,The results also showed that its leaf funct ion per iod lasted longer,it was beneficial for kernel filling.Yumai 18had fast kern el filling,high grain weight;Yumai 21had slowest kernel filling,low 1000 kerne l weight and lower yield;comparing Yumai 49 with 93zhong6 ,in pre-fillin g sta ge, yumai 49 surpass 93zhong6 ,but in later stage, 93zhong6 exceed yumai 49. 93zhong6had thehighest NRA, Yumai 18 was second, Yumai 21 was thir d,yumai 49 was the lowest.
