The study on the phylogenetic relations among these species is very useful for the study on genome and marker-assisted breeding in Brassica species. The karyotypic analysis is one of the most important methods in analysing the phylogenetic relation of species with closer relations. The protocol for inducing high frequency metaphase was established by pretreatment with low temperature and 8hydroxyquinoline, and then the preparation of chromosome and karyotypes analysis of six economical important Brassica species were carried out. According to the karyotypic analysis, it was shown that in the genomes of amphidiploid species, there are genomical components from didiploid species. Our result showed that B. campetris, B. juncea and B. napus belonged to class 2B, while B.

以二倍体B.nigra（B，n=8）基因组为探针，用B.campestris（A，n=10）或B.oleracea（C，n=9）的基因组进行封阻，分别与B.juncea（AB，n=18）和B.carinata（BC，n=17）进行GISH杂交发现，B.juncea和B.carinata基因组中仅有来自于B.nigra的8对染色体表现杂交信号，而其它染色体杂交信号较弱；以B.campestris或B.oleracea基因组为杂交探针与B.napus（AC，n=19）进行GISH杂交发现，所有19对染色体均出现杂交信号，根据杂交结果难以正确判断B.napus基因组中的哪些染色体是来自于A基因组，哪些是来自于C基因组；以rRNA基因（18S-5.8S-26S）为探针的FISH杂交结果表明，B.campestris基因组中rRNA基因位点为6对；B.oleracea为3对；B.nigra为2对；B.carinata为4对；B.juncea为6对；B.napus为6对。

An Austrian pathologist identified the first two red cell antigens, A and B, in 1900. In the 1940s, he identified a further class of antigen, the rhesus factor, named after the monkeys in which the discoery was made.

1900年，一位奥地利的病理学家发现最初两种红细胞抗原，即A和B抗原。20世纪40年代，他发现了又一类抗原，即猕因子，以在其身上作出此发现的猴子命名。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
