与遗传型“三系”法、“二系”法相比,利用化学杀雄技术配制杂种一代具有制种程序简便、省工、省时的优点,并能避免将优良杂交组合的亲本转育为不育系、恢复系时,带来不良基因的弊端,因此,化学杀雄在小麦杂种优势利用上有着光明的前景。
Compared with the genetic “three lines” method and “two lines” method, the use of chemical killing techniques to formulate the hybrid generation has the advantages of simple, labor-saving and time-saving seed production procedures and avoids the transfer of the parents of the fine hybrid combination to CMS, Restorer system, bring the drawbacks of bad genes, therefore, chemical Killing male heterosis utilization in wheat has a bright future.
