Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.

对上述研究结果分析表明：（1）芸薹属复合种是由基本种相互杂交而成；（2）B基因组与A或与C基因组亲缘关系较远，而A和C基因组亲缘关系较近；（3）芸薹属复合种在演化过程中，发生了染色体结构上的重排现象；（4）芸薹属复合种演化过程中，rRNA基因位点发生了减少；所获结果与国外同类报道相比表明：国内的白菜型油菜存在新的rRNA基因位点，即rRNA基因在芸薹属同一物种不同的品种间具有多态性；有关这类研究国内尚未见报道。

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。

Wheat germplasm lines were obtained from the posterity of Aegilops tauschii-Triticum Carthlicum amphiploid, and analysis results showed that the 30 germplasm lines have many excellent characters, such as multi-tillers, multi-spikes per plant, good disease resistance, large ear, etc., they are very useful in genetic improvemert of wheat.
