部分现代月季品种的细胞学研究

作者通过对13个现代月季品种的染色体数目的观察和12个品种的核型分析,得到以下结果:‘明星’(‘Super Star’)2n=4X=28=24m+4sm,核型为1A型;‘墨红’(‘Crimson Glory’)2n=4x=28=28m,核型为1A型;‘粉和平’(‘Pink Peace’)2n=4x=28=28m,核型为1A型;‘钮扣黄’(‘Goldilocks’)2n=4x=28=20m+8sm,核型为1A型;‘卖花女’(‘Flower Girl’)2n=4X=28=24m+4sm,核型为1A型;‘杏花村’(‘Betty Prior’)2n=3x=21=21m,核型为1A型;‘法国小姐’(‘MissFrance’)2n=4x=28=28m,核型为1A型;‘白雪山’(‘Mount Shasta’)2n=4x=28=28m,核型为1A型;‘二重奏’(‘Duet’)2n=4x=28=28m,核型为1A型;‘金光’(‘Gold Glow’)2n=4x=28=28m,核型为1A型;‘花旗藤’(‘American Pillar’)2n=3x=21=18m+3sm,核型为1A型;‘桃色奶油’(‘Peaches’Cream’)2n=3x=21=21m,核型为1A型;‘博尼卡’(‘Bonica’)2n=3x=21.文中对现代月季品种的起源及其表现型在细胞遗传上的体现,进行了初探。

A STUDY ON CHROMOSOMES OF SOME MODERN ROSE CULTIVARS

The present paper reports chromosome numbers of 13 modern rose cultivars, and karyotypes of 12 cultivars among them. They are: 'Super Star' 2n = 4x = 28 = 24m+ 4sm,lA type; 'Grimson Glory' 2n = 4x = 28 = 28m, 1A type ; 'Pink Peace' 2n = 4x = 28 = 28m, lA type; 'Goldilocks' 2n = 4x= 28 = 20m+ 8sm, 1A type; 'Flower Girl'2n = 4x = 28 = 24m + 4sm, lA type ; 'Betty Prior' 2n = 3x= 21 = 21m, 1A type; 'Miss France' 2n = 4x = 28=28m, lA type; 'Mount Shasta' 2n = 4x = 28 = 28m, lA type; 'Duet' 2n = 4x = 28 = 28m, 1A type ; 'Gold Glow' 2n = 4x = 28 = 28m, lA type ;'American Pillar' 2n= 3x = 21 = 18m + 2sm, 1A type; 'Peaches Cream' 2n = 3x = 21 =2lm, 1A type; 'Bonica' 2n = 3x = 21. Problems about origin and manifestation of modern rose cultivars were briefly discussed.
