湖南野生宽皮柑桔核型研究

Karyotype of Loose Wild Mandrins in Hunan

对湖南 4种野生宽皮柑桔和 5种栽培宽皮柑桔的核型进行了比较研究 .结果表明 :通道野桔 2 n=2 x =16 =16 m +2 sm ,道县野桔 2 n=2 x =18=16 m +2 sm ,莽山野桔 2 n=2 x =18=16 m +2 sm ,莽山野柑 2 n=2 x =18=18m ,永顺蜜桔 2 n =2 x =18=10 m +8sm,土桔 2 n =2 x =18=14m +4 sm,朱桔 2 n =2 x =18=12 m +6 sm,红桔 2 n =2 x =18=8m +8sm +2 st,玛瑙柑 2 n =2 x =18=8m +10 sm.比较 9个材料的核型 ,莽山野柑是原始的柑类 ,通道野桔、道县野桔。

The karyotypes of 4 wild loose mandarins and 5 cultivated ones were examined. The results showed that Tongdao wild tangerine 2n=2x=18= 16m+2sm,Daoxian wild tangerine 2n=2x=18= 16m+2sm,Mangshan wild tangerine 2n=2x=18= 16m+2sm,Mangshan wild Mandarin 2n=2x=18= 18m,Yongshun tangerine 2n=2x=18= 10m+8sm,Tuju tangerin 2n=2x=18= 14m+4sm,Zhujutangerine 2n=2x=18= 12m+6sm,Hongju 2n=2x=18= 8m+8sm+2st,Manao mandarin 2n=2x=18= 8m+10sm.Comparing the karyotypes of 9 subjects,it is concluded that Mangshan mandarin is the primitive type of mandarins,while Tongdao wild tangerine,Daoxian wild tangerine,and Mangshan wild tangerine are the primitive type of tangerine.
