Viola ×wittrockiana Gams.%Chromosome%Karyotype analysis
利用常规压片法对大花三色堇（Viola ×wittrockiana Gams．）3个品种的染色体数与核型进行分析。结果显示：3个品种的染色体组成复杂多样，其核型公式依次为‘EP1’2n＝2x＝43＝2M＋7m（1SAT）＋4sm＋24st＋6t，‘XXL-G’2n＝2x＝36＝2M＋14m（2SAT）＋16sm＋4st，‘M-BF’2n＝2x＝42＝24m＋18sm；三者的核型不对称系数分别为78．0％、65．0％、62．1％，‘1’、‘-’的核型均为2型，‘-’的核型为2型。
利用常規壓片法對大花三色堇（Viola ×wittrockiana Gams．）3箇品種的染色體數與覈型進行分析。結果顯示：3箇品種的染色體組成複雜多樣，其覈型公式依次為‘EP1’2n＝2x＝43＝2M＋7m（1SAT）＋4sm＋24st＋6t，‘XXL-G’2n＝2x＝36＝2M＋14m（2SAT）＋16sm＋4st，‘M-BF’2n＝2x＝42＝24m＋18sm；三者的覈型不對稱繫數分彆為78．0％、65．0％、62．1％，‘1’、‘-’的覈型均為2型，‘-’的覈型為2型。

An experiment was conducted to study the chromosome numbers and karyotypes of three pansy cultivars by common plates-making.The karyotype formula of three cultivars of Viola ×wittrockiana Gams are as follows, the karyotype formula of‘EP1’,‘XXL-G’ and ‘M-BF’ are 2n=2x=43=2M+7m(1SAT)+4sm+24st+6t, 2n=2x=36=2M+14m(2SAT)+16sm+4st and 2n=2x=42=24m+18sm, respectively.Their asymmetry indexes are 78.0%, 65.0% and 62.1%, re-spectively.The karyotypes of‘EP1’ and ‘M-BF’ belong to 2B, while ‘XXL-G’ belongs to 2A.
