摘　　要：以晋麦84号、烟农19、舜麦1718为试验材料,每个品种千粒质量分为大、中、小3个处理,并进行两极选择,研究不同品种不同处理不同年份间6种农艺性状的差异。结果表明,在分蘖数、成穗数中,重穗型品种晋麦84号大粒与小粒处理达显著水平,不同年份间大粒与小粒处理也达到显著水平。在两极选择后,各农艺性状处理间相比,增幅有扩大趋势,除穗粒数外,成苗数、分蘖数、成穗数、千粒质量、产量性状从小粒到大粒处理的后代数值均有递增趋势。Three varieties Jinmai 84,Yannong 19 and Shunmai 1718 as material,they were divided into big,middle and small thousand grain weights three treatments,and were chosen extremely,and difference between 6 agronomic performances between different varieties,treatments and years were studied.The results indicated that Jinmai84 showed significant difference between big and small grain treatments and the different years in heavy spike variety.After polar choice,in comparison between the various agronomic performances,an expanding tendency in growth was shown.Expect kernels per spike,the seedling number,tiller number,ear yield,thousand grain weight,yield in posterity of small to big grain weight treatments,all had a trend of increasing.
