植物育种意味着创造遗传变异以及在变异中进行选择。对面包小麦品质的育种也要求选择合适的品质测定方法。这种测定方法的选择,十分需要了解市场和磨粉及烘烤业的要求。不论快速筛选早代品系籽粒品质的复杂方法还是品种评价及杂交亲本研究中的先进测定方法,都需要有一个较宽的品质测定方法系列,也必须有一个测定磨粉品质、烘烤品质和抗穗发芽的测试方法系列。对优质杂交亲本和优质基因来源的选择是育种家工作中的一个重要组成部分。必须选择出适于市场需求的品质类型.为了配制杂交组合和指导选择,育种家也应尽可能多的了解这些品质基因的遗传特性。略微复杂一点,除复杂的品质性状外,育种家还必须考虑25个其他更复杂的重要性状。
Plant breeding means creating genetic variation and choosing among variations. Breeding of bread wheat quality also requires the selection of a suitable quality test method. The choice of this measurement method, it is necessary to understand the market and milling and baking industry requirements. Regardless of the complex methods used to rapidly screen the grain quality of early generations of lines, the evaluation of cultivars, and the advanced methods used in the study of crossed parents, there is a need for a broad range of methods for the determination of quality, as well as a system for measuring milling quality, baking quality and resistance Spike germination test method series. The choice of a good hybrid parent and a good source of quality genes is an important part of the breeder’s work. The type of quality that has to be adapted to the needs of the market has to be chosen, and breeders should also know as much as possible about the genetic characteristics of these quality genes in order to formulate crossings and guide choices. Slightly more complicated, in addition to complex quality traits, breeders must consider 25 other more complex and important traits.
