8个LA百合品种的核型分析
Karyotype analysis of eight LA hybrid lilies
摘要
Abstract
[Objective]The genetic characteristics of LA hybrid lilies were analyzed to provide useful information of par-ents selection and hybrids identification in lily breeding.[Methods]The chromosome number and karyotype of 8 LA hy-brid lilies were analyzed using traditional squash method,and were observed by Olympus(BX-51)microscope.[Re-sults]All of the 8 LA hybrids were triploid(2n=3x=36).The karyotype of 'Serrada' was 3A,and the others were 3B.The asymmetry indexes were ranged from 71.84% to 76.33%.The chromosomes were mainly composed of 2-3 median chromosomes(m)or submedian chromosomes(sm),subterminal chromosomes(st)and terminal chromosomes (t).The position and number of secondary constrictions were different among all 8 LA hybrids.[Conclusion]The chro-mosome satellite and the secondary constriction could be used to identify hybrid progenies in early stage.Most of the LA lilies contain genome recombinant chromosomes,which can be used for screening the plant with good target traits in hybrid progenies.关键词
