在作物育种工作中,利用单倍体方法,能有效地简化遗传模式,控制杂种分离,迅速获得纯个体,大大缩短育种年限,提高选择效果。由于棉花的花培和珠培难度较大,国内外至今均未诱导出单倍体成苗植株。为此,河北省农科院棉花研究所于1980年承担了院委托课题“棉花单倍体育种技术的研究”, In crop breeding, the haploid method can effectively simplify the genetic model, control hybrid segregation, quickly obtain pure individuals, greatly shorten the breeding years and improve the selection effect. Due to the difficulty of cotton flower cultivation and pearl cultivation, so far no haploid seedlings have been induced at home and abroad. To this end, the Cotton Research Institute of Hebei Academy of Agricultural Sciences in 1980 assumed the commission commissioned a project “cotton haploid breeding technology research”
