6) allotetraploid hybrids
异源四倍体鲫鲤
1.
Both the males and females of the tetraploids with 200 chromosomes were obtained from the offsprings (G_1×AT) produced by mating the eggs of G_1 with the diploid sperms from the allotetraploid hybrids.
二倍体雌核发育第 1代 (G1)产生的二倍体卵子经紫外线灭活的散鳞镜鲤精子诱导 ,无需染色体加倍处理 ,发育成二倍体雌核发育第 2代 (G2 ) ;G1 产生的二倍体卵子与雄性异源四倍体鲫鲤 (AT)产生的二倍体精子结合 ,形成新型两性可育的异源四倍体鲫鲤 (G1 ×AT)。
