| 摘 要： | 采用常规压片法对来源于我国不同省份的8个大粒裸燕麦品种进行了核型分析及进化趋势研究,旨在为燕麦种质资源的收集,鉴定,开发利用和良种培育提供细胞学依据.研究结果表明,8份大粒裸燕麦材料的核型公式分别为:青莜3号:2n=6x=42=22m+20sm (4SAT);平安莜麦:2n=6x=42=18m+24sm (4SAT);白燕2号:2n=6x=42=18m+24sm (2SAT);花早2号:2n=6x=42=20m+22sm (2SAT);花晚6号:2n=6x=42=14m+28sm (6SAT);晋燕8号:2n=6x=42=22m+20sm (4SAT);宁莜1号:2n=6x=42=16m+26sm (2SAT);定莜6号:2n=6x=42=16m+26sm (4SAT),8个燕麦品种的核型均属于2B型.进行聚类及进化趋势分析发现,白燕2号为最进化的品种,青莜3号为最原始的品种.

| Abstract: | In order to provide cytological information for the collection,identification,utilization and breeding of Avena nuda germplasm,karyotype analysis and an evolution trend investigation have been undertaken of 8 A.nuda cultivars from different provinces of China using the conventional tableting method.The karyotype formulas of the 8 cultivars as follows:Qingyou No.3:2n=6x =42=22m+20sm (4SAT);Pingan:2n=6x =42=18m+24sm (4SAT);Baiyan No.2:2n=6x =42 =18m+24sm (2SAT);Huazao No.2:2n=6x =42 =20m+22sm (2SAT);Huawan No.6:2n=6x =42=14m+28sm (6SAT);Jinyan No.8:2n=6x =42=22m+20sm (4SAT);Ningyou No.1:2n =6x =42 =16m+26sm (2SAT);Dingyou No.6:2n =6x =42 =16m+26sm (4SAT).The karyotype of the 8 cultivars belongs to the 2B type.According to clustering and evolution-ary trend analysis,Baiyan No.2 is a relatively new cultivar and Qingyou No.3 is the most original cultivar. |
