摘要

获得了二倍体雌鱼和异源三倍体雄鱼的眼胚和幼鱼。有两组,一组染色体数为79-83(组I),另一组染色体数为110-112(组II)。从染色体的数目和构成来看,推测组I个体数为2.5n,组II个体数为3.5n。所有幼鱼均为3.5n,至1990年9月仍有2只幼鱼存活,约7个月后孵化。

The viable 3.5n trouts produced between diploid females and allotriploid males.
Eyed embryos and fingerlings of trouts between diploid females and allotriploid males were obtained. There were two groups, namely, one group with the chromosome number of 79-83 (group I), and another with that of 110-112 (group II). Judging from numbers and constitutions of the chromosomes, it is presumed that the individuals in group I were 2.5n and those in group II were 3.5n. All fingerlings were 3.5n, and 2 fingerlings of them were still surviving as of September, 1990, about 7 months after the hatching.
