1980年我们从中国农科院引入太谷核不育小麦种子(为叙述方便,简称BT),经过试种鉴定,认为BT材料皆为杂合体,后代严重分离,遗传基础较为丰富,通过去劣留优,可作为基因库使用。借鉴常规育种的经验,参考玉米轮回选择的做法及国内外在小麦育种中提出的种种轮回选择方案,我们提出了阶梯式群体改良选择法(见下图),并进行了初步尝试。这种
In 1980, we introduced Taigu nuclear sterile wheat seeds from Chinese Academy of Agricultural Sciences (for ease of description, referred to as BT), after trial identification, that all BT materials are heterozygous, serious separation of offspring, the genetic basis is more abundant, Stay good, can be used as a gene pool. With reference to the experience of conventional breeding, referring to the practice of maize reincarnation and the options of reincarnation proposed in wheat breeding both at home and abroad, we propose a step-by-step group improvement selection method (see below) and make a preliminary attempt.
