普通小麦品种间染色体代换系为小麦籽粒的物理及生化特性研究,在遗传学上提供了广阔领域。通过对增加籽粒大小、数量、烘烤、营养品质及籽粒某些生物化学特性遗传变化的研究,将有助于小麦育种产量的进一步提高。本文主要目的,应用栽培品种“厚普”在“中国春”上的21个品种间染色体代换系,对蛋白质含量和粒重两个性状进行研究,并分析其遗传差异。蛋白质含量。小麦籽粒蛋白质含量在遗传学上有许多研究,克拉克等研究,它是受多基因控制的;霍诺德等认为是少数几个主要基因和未确定数量的修饰基因可能控制蛋白 Chromosome substitution lines among common wheat varieties are the physical and biochemical characteristics of wheat grains and provide a genetically broad field. Studies of genetic changes that increase grain size, quantity, toasting, nutritional quality, and certain biochemical characteristics of the grain will contribute to further increases in wheat breeding yield. The main purpose of this paper is to study the genetic relationship between 21 cultivars with “Pan-Pu” cultivars in Chinese Spring. Protein content. There are many genetic studies on the grain protein content of wheat, Clarke and other studies, it is controlled by multiple genes; Hornod, etc. considered a few major genes and undetermined number of modified genes may control the protein
