The work was carried out in 1984-1986 on the ploidy composition of parthenogenetic Anemia (A. parthenogenetica) collected from eight saltfields of North China. Pentaploid Anemia has been found in seven of the eight saltfields, but we have not found tetraploid Anemia in these saltfields. Based on ploidy check, parthenogenetic Anemia clones, penta-ploid 8 and diploid 7, were established. In these clones, the cyst diameter (averaging 286μm) of the pentaploid is larger than that (250μm) of the diploid....

The work was carried out in 1984-1986 on the ploidy composition of parthenogenetic Anemia (A. parthenogenetica) collected from eight saltfields of North China. Pentaploid Anemia has been found in seven of the eight saltfields, but we have not found tetraploid Anemia in these saltfields. Based on ploidy check, parthenogenetic Anemia clones, penta-ploid 8 and diploid 7, were established. In these clones, the cyst diameter (averaging 286μm) of the pentaploid is larger than that (250μm) of the diploid. In diploid clones, a few of male individuals were born now and then. Isozyme analysis of AKP (3.1.3.1.) and TO by PAGE showed that there are obvious differences between the diploid and the pentaploid- The chromosomes of Anemia parthenogenetica differ from that of American's bisexual brine shrimp (Anemia franciscana) in having four satellites and nucleolus organizers in China diploid Anemia's completement. Studies of the gonad cells proved that the pachytene chromosomes of the diploid could be distinguished and characterized morphologically. In A. franciscana, every pachytene chromosome pair could be distinguished from each other by its heterochro-matin mass and length. Chromosomes of China Anemia are obviously different from those of American's.

本研究于1984—1986年完成。查了华北八个盐场卤虫卵的倍性组成,共建立不同盐场卤虫的五倍体克隆8个、二倍休克隆7个,并用银染技术对孤雌生殖二倍体卤虫的染色体进行了研究。通过实验得到以下结果:1.发现华北孤雌生殖卤虫有五倍体存在;2.将五倍体与二倍体卤虫两者相比,在许多方面有明显差异;3.华北孤雌生殖二倍体卤虫染色体具有典型的减数分裂行为,与美国旧金山两性生殖二倍体卤虫的粗线期染色体有很大差别。

All triploids were produced by mating female diploids and male tetraploids in Pacific oyster, Crassostrea gigas Thunberg (referred to as DT groups), along with diploid controls using eggs from the same female diploids (referred to as DD groups). Tetraploid brood stocks were introduced from USA with the help of the 4C Company. Upon arrival at the experiment sites, tetraploid brood stocks were kept in seawater at 4℃ till use to prevent spontaneous spawning. Both eggs and sperm were obtained by strip spawning....

All triploids were produced by mating female diploids and male tetraploids in Pacific oyster, Crassostrea gigas Thunberg (referred to as DT groups), along with diploid controls using eggs from the same female diploids (referred to as DD groups). Tetraploid brood stocks were introduced from USA with the help of the 4C Company. Upon arrival at the experiment sites, tetraploid brood stocks were kept in seawater at 4℃ till use to prevent spontaneous spawning. Both eggs and sperm were obtained by strip spawning. Fertilization levels ranged from 47.4% to 88.9%, averaging 69.5% in DT groups, while the mean fertilization in DD controls was 91.4%. There was significant difference in fertilization success between the DT and DD groups ( P <0.01). Compared with DD groups, the reduction in fertilization in DT groups was primarily attributed to high egg density in order to fully utilize sperm from tetraploids. Survival from fertilized eggs to D stage larvae and spat averaged 53.9% and 1.3% respectively in DT groups, compared to 61.6% and 1.9% respectively in controls. There was no significant difference in survival to D stage and spat between DT and DD groups. The total amount of eyed larvae and spat obtained from DT groups were 832.4 M and 184.3 M respectively. Larvae from DT groups were slightly larger than those from controls throughout larval development. However, larvae from DT and DD groups had the similar growth following formation of straight hinge larvae. Flow cytometry is used to verify the ploidy composition of tetraploid brood stock and of progeny from DT groups. Random samples of D stage larvae, eyed larvae and spat from DT groups were consistently 100% triploids. The key point of producing all triploids by crossing tetraploids with diploids was the prevention of contamination from diploid cultures, especially when diploid progeny were cultivated simultaneously. There were evidences that contamination of diploids resulting in remarkable reduction in triploid percentage of previously verified 100% triploid stocks in some of the replicates in this study. Results presented here demonstrate that female diploid C. gigas stocks from North China could be readily mated with male tetraploids from USA and produce 100% triploids on a large scale. Overall, this study shows that tetraploids are extremely valuable for large scale of production of triploids, and mating diploids and tetraploids is an ideal approach of all triploid production in C. gigas.
