| 摘 要： | 为了解基因型对小麦生物产量和籽粒产量的影响,选取7个不同基因型的小麦品种(系)作为供试材料,对其生物产量、籽粒产量与收获指数的差异进行了比较研究,并对生物产量与籽粒产量及其构成要素的关系作了分析。结果表明:不同基因型小麦的生物产量、籽粒产量和收获指数均存在差异,镇麦168的生物产量居首位,达到1656.3 g/m2,但其收获指数仅为0.45,导致其籽粒产量不高;宁麦13的生物产量较高,收获指数和籽粒产量均为最高。不同基因型小麦的籽粒产量与生物产量呈正相关关系,每穗实粒数、千粒重与生物产量相关不密切。

| Abstract: | In order to find out the effects of genotype on the biomass and grain yield of wheat,we analyzed the differences in biomass,grain yield and harvest index among 7 genotypes of wheat varieties.In addition,the relationship between biomass and grain yield and its components was studied.The results showed that the differences in biomass,grain yield and harvest index were all found among various wheat genotypes."Zhenmai 168" had the highest biomass,which was 1656.3 g/m2,but its harvest index was just 0.45."Ningmai 13" had relatively high biomass,and the highest grain yield and harvest index.There was positive correlation between grain yield and biomass yield of different wheat genotypes,while the filled grain number per spike,1000-grain weight and biomass were not closely related. |
