Karyotype Analysis of Five New Lilium Asiatic Cultivars
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.
