一、前述单倍体育种作为缩短育种年限的有效方法,已被广泛应用。现阶段,大麦的单倍体育种方法有两种,即花药培养法和野生大麦育种法。通过单倍体育成率的比较试验,后者比前者具有更高的成功率。花药培养法,由于尚未探明的原因,较多的出现叶绿体欠缺、中途生长停止的现象,单倍体育成率不足1%。但是,野生大麦育种法能够以20%以上的成功率育成单倍体,具有很高的实用性。
First, the aforementioned haploid breeding as an effective method to shorten the breeding years, has been widely used. At this stage, barley haploid breeding methods are two, namely, anther culture and wild barley breeding method. Through the comparative test of haplogroup success rate, the latter has a higher success rate than the former. Anther culture method, due to the reasons not yet proven, more chloroplast lack of growth stopped halfway phenomenon, haploid sports rate of less than 1%. However, the wild barley breeding method can be haploid with a success rate of more than 20%, which is of high practicability.
