摘要
对药剂诱导玉米孤雌生殖选育自交系和单倍体活体诱导玉米孤雌生殖,两种育种模式通过试验做了比较,两种方法获得纯合稳定自交系的年限是一样的,育种周期一般比传统的可缩短1/2以上;但从高效和实际应用方面,利用药剂诱导玉米孤雌生殖直接产生纯合二倍体的选系方法优于单倍体诱导选系方法。
In the paper,two kinds of corn breeding patterns,pharmaceutical induction and haploid induction breeding inbred lines of maize,were compared by testing. Two kinds of methods to obtain stable homozygous inbred lines is the same as the number of years,than traditional breeding cycle is generally more than half can be shortened. From modern and efficient and practical applications,the use of drug-induced parthenogenesis corn to produce homozygous diploid direct election system is superior to the election system haploid induction method.
