摘要: 为了给百合杂交育种提供细胞遗传学依据,采用常规压片法,进行了5个新颖亚洲百合品种的核型分析。结果表明:5个亚洲百合品种均为二倍体,染色体24条。‘Original love’的核型公式为2n=2x=24=4sm 18st 2t,‘Ceb dozzle’的核型公式为2n=2x=24=16sm(3SAT) 8st,‘Indian summerset’的核型公式为2n=2x=24=2sm 22st,‘Red alert’的核型公式为2n=2x=24=6sm 18st,‘Party diamond’的核型公式为2n=2x=24=22st(3SAT) 2t(2SAT)。5个品种均为3B型核型。‘Party diamond’的核型不对称系数为91.67%,其余4个品种的核型不对称系数范围在73.13%~79.37%之间。‘Ceb dozzle’、‘Party diamond’ 2品种染色体有随体,其他3个品种无随体。本研究将为百合杂交育种的亲本选配和杂种早期鉴定提供细胞遗传学依据。

Abstract: To provide cytogenetics basis for Lilium cross breeding, we studied the karyotypes of five new Asiatic lily cultivars by using traditional tabletting method. The results showed that: five Asiatic lily cultivars were diploids with 24 chromosomes. The karyotype formula of ‘Original love’ was 2n =2x= 24 = 4sm 18st 2t, the formula of ‘Ceb dozzle’ was 2n =2x=24 = 16sm (3SAT) 8st, the formula of ‘Indian summerset’ was 2n =2x= 24 = 2sm 22st, the formula of ‘Red alert’ was 2n =2x= 24 = 6sm 18st, the formula of ‘Party diamond’ was 2n =2x= 24 = 22st (3SAT) 2t (2SAT). Five cultivars belonged to 3B karyotype. The asymmetrical karyotype coefficient of ‘Party diamond’ was 91.67%, those of the other four cultivars were 73.13%-79.37%. The chromosomes of ‘Ceb dozzle’ and ‘Party diamond’ had satellites, but the other three cultivars had not satellite. This study will provide cytogenetics basis for parents selection and early hybrid identification of Lilium cross breeding.
