转基因材料与黑河骨干亲本杂交后代选育方法的探讨
|
摘要
为选育高寒地区抗逆性强的大豆品种,利用2份外引转基因材料与10份黑河骨干亲本配置杂交组合,对其杂交后代进行有效选择。结果表明:转基因材料与常规材料杂交的后代与常规杂交后代并无区别,后代材料的选择遵循孟德尔的遗传规律。转基因杂交低代不可淘汰组合,防止目标基因的丢失,高世代选择与常规选择手段相同,同时结合室内检测,对各世代选择过程中出现的问题进行探讨。
In order to breed soybean varieties with strong stress resistance in alpine regions,using 2 duplicates cited transgenic materials with 10 copies of Heihe backbone parents to configurate hybrid combinations,its offspring were chosen effectively.The results showed that:there were no difference between the hybrids of transgenic materials with conventional and conventional hybrids,the choice of the descendants materials followed Mendelian genetic law.Transgenic hybrid low generation could not eliminated combinations,avoid preventing the loss of the target genes,the choice method of high-generation and conventional choice was the same,combined indoor detect,the problems existing in generations selection process were discussed.
