五寨莜麦Ａｖｅｎａｎｕｄａ是我区栽培历史悠久的农家品种。在燕麦属中它是染色体数目比较多的种。我们对其染色体数目及其核型进行了观察研究。五寨莜麦是六倍体种２ｎ＝６Ｘ＝４２，染色体核型公式为２ｎ＝６Ｘ＝４２＝２６ｍ＋１０ｓｍ（２ＳＡＴ）＋６ｓｔ，核型类别为２Ｂ。
Wuzhai 莜 Mai Avenanuda is our region has cultivated a long history of farm varieties. In the genus Avena it is the number of chromosomes more. We observed the number of chromosomes and their karyotypes. Wuzhai obscurus is hexaploid species 2n = 6X = 42, the chromosome karyotype formula is 2n = 6X = 42 = 26m + 10sm (2SAT) + 6st and the karyotype is 2B.
