查询词典 autotetraploidy

It is suggested that autotetraploidy rices are better females in the distant hybridization due to the fact that they are weaker in sexually reproductive ability.

结果暗示由于同源四倍体水稻具有比较弱的有性生殖能力，在远缘杂交中它们是比较好的杂交母本。

In the crosses of the autotetraploidy rices used as the females, some seeds could be got, but more seeds were obtained in these crosses by the special treatment that the DH solution was put into the caryopses before the pollination.

在以同源四倍体水稻为杂交母本的杂交组合中，可以获得一些实粒种子，但是，如果在授粉前利用DH溶液对同源四倍体水稻的去雄颖花进行处理后再授狼尾草的花粉粒则能获得更多的实粒种子。

In crossing of the 8 autotetraploidy rices (Oryza sativa, 2n=4x=48), APIV(4), IR36(4), Zixuedao(4), Ce 64(4), Minghui 63(4), IR28(4), Ce 90(4) and Gui 99(4) used as the females, with Pennisetum alopecuroides (2n=2x=18) used as the males, the seeds were obtained, but no seed was got in the crosses of the 3 diploidy rices (Oryza sativa, 2n=2x=24), APIV(2), Ce 90(2) and Zixuedao(2) used as the females, with Pennisetum alopecuroides.

利用APIV(4)、IR36(4)、紫血稻(4)、测64(4)、明恢63(4)、IR28(4)、测90(4)和桂99(4)等8个同源四倍体水稻(Oryza sativa， 2n=4x=48)为杂交母本，以狼尾草(Pennisetum alopecuroides， 2n=2x=18)为杂交父本进行杂交，获得了实粒种子。但是，在以APIV(2)、测90(2)和紫血稻(2)这3个二倍体水稻(Oryza sativa， 2n=2x=24)为杂交母本，以狼尾草为杂交父本的杂交组合中却没有获得实粒种子。

The split between the two groups can hardly be papered over.
