Genetic heredity experiments showed that the inheritance of the melanic characteristics was incomplete dominance and autosomal and followed the Mendalian law.

结果表明，SEM蛹黑化性状的遗传是不完全显性遗传，遵循孟德尔的不完全显性遗传规律，控制黑化性状的基因位于常染色体上，与性染色体无关。

Genetic experiments showed that the inheritance of the melanic character followed the Mendalian imcomplete dominance law. A single pair of genes regulated the melanic character.

遗传实验结果表明，甜菜夜蛾突变品系和正常品系的蛹体色遗传模式遵循孟德尔的不完全显性遗传规律，黑色性状由位于常染色体上的单基因控制。

Based on the genetic distance of 26% by SSR data, the cluster analysis with un-weighted pair-group method using arithmetic averages produced 2 major clusters: cluster Ⅰ of higher degrees of genetic differentiation and Cluster Ⅱ of lower degrees of genetic differentiation relatively, which are composed of 30 cultivars, and another cluster of much higher degrees of genetic differentiation, which is only composed of the cultivars of FHIA 25 and Pisang Jari Buaya.

依据26%的遗传距离，除了FHIA25和Pisang Jari Buaya单独化成1组外，其它30个品种可以分为2组：品种间遗传差异相对较高的组Ⅰ和品种间遗传差异相对较低的组Ⅱ。

The polymorphism information content ranged from 0.00 to 0.88 and averaged 0.62. The averaged pair wise genetic distances among cultivars were estimated from 0.00% to 34.27% with an average of 12.45%, which revealed a narrow range of variability among cultivars, except for FHIA 25, Yangambi KM 5, Pisang Jan Buaya, Rose and Huangdijiao.

依据SSR数据计算的品种间遗传距离在0.00%~34.27%，平均12.45%，大多数品种间的遗传变异非常有限，但也存在着遗传差异突出的品种：FHIA25、Yangambi KM 5、Pisang Jari Buaya、Rose和皇帝蕉。

The physical maps of mtDNAs from N.taihuensis Chen,Salvelinus taxa and Salmo salar were analyzed.Genetic distances between mtDNAs were calculated by the formula of Nei and Li(1979).Phylogenetic reconstruction method,UPGMA,was used to analyze the genetic relationships and the molecular dendrogram was established and revealed:the genetic distance between Salvelinus taxa and Salmo salar is 12.23% and that between N.taihuensis Chen and Salvelinus taxa-S.salar is 21.36%.Thisc indicates that Salangidae diverged from Salmoninae earlier.

比较了鲑形目3种鱼的线粒体DNA物理图谱，根据限制性位点差异法计算它们之间的遗传距离，利用UPGMA聚类分析法构建分子聚类图，结果表明：红点鲑属与大西洋鲑先聚在一起，再与太湖新银鱼相聚，前两者间遗传距离为12.33%，亲缘关系较近，太湖新银鱼与这两者间的遗传距离为21.36%，亲缘关系较远，表明银鱼科与鲑科分离较早。
