| 摘 要： | 对野豌豆属(Vicia)4个不同品种(系)的根尖细胞有丝分裂中期染色体进行数目统计及核型分析。结果显示，4个品种(系)的染色体数目相同，均为2n=2x=12；但核型公式和核型类型各不相同，春箭筈豌豆品种“兰箭3号” (Vicia sativa Lanjian No.3)和狭叶野豌豆品种333/A (V. angustifolia 333/A)的核型公式分别为2n=2x=8m+2sm+2st和2n=2x=2m+8sm(2SAT)+2st，春箭筈豌豆品系2556、2560的核型公式均为2n=2x=10m+2sm；兰箭3号和品系2556的核型类型均为“2B”，品系2560的核型类型为“1B”，而品种333/A的核型类型为“3B”。表明不同品种(系)春箭筈豌豆之间具有染色体遗传多样性。

| Abstract: | The chromosome numbers and karyotypes of four varieties (lines) of Vicia were studied by the root tip cells. The results indicated that the chromosome numbers of all four varieties (lines) were the same, 2n=2x=12. The karyotype formulas of V.sativa Lanjian No. 3 and V.angustifolia 333/A were 2n=2x=8m+2sm+2st and 2n=2x=2m+8sm (2 SAT)+2st, respectively, while V. sativa 2556 and V.sativa 2560 were the same with 2n=2x=10m+2sm . The karyotype of Lanjian No.3 and 2556 were 2B types, while 2560 with 1B type and 333/A with 3B type. These results demonstrated that some genetic differentiations were existed among different varieties (lines) of V.sativa. |
