目前,小麦育种工作的基本方法,仍是采用品种间有性杂交,这一常规育种方法是:通过杂交,创造变异,从中选出具有优良性状的单株,经培育和选择,育成小麦新品种。要选育新品种必须了解其遗传规律,以便很好地选配亲本和进行后代的选择。现试谈遗传方面的几个问题。一、亲本选配问题杂种后代的性状,是由双亲通过性细胞传下来的遗传物质,在环境条件的影响下形成的。不同的品种具有不同的遗传物
At present, the basic method of wheat breeding still uses sexual hybridization among breeds. The conventional breeding method is to breed new varieties of wheat by breeding and selecting single plants with excellent traits by crossing and creating variation . To breed new varieties must understand its genetic law, in order to well match the choice of parents and offspring. Here are a few questions about the genetic aspects. First, the parent matching problem Traits of hybrid offspring, is inherited by parents through the sex cells down genetic material, formed under the influence of environmental conditions. Different breeds have different genetic material
