猕猴桃属十个种的染色体倍性鉴定
Chromosome ploidy of ten species in genus Actinidia
摘要
Abstract
The genus Actinidia contains more than 66 species and 118 taxa(In the latest revision of the genus, all of them were classified as 54 species and 21 varieties),and most of them were Chinese endemic.As we know,inappropri?ate mating between parents with different ploidies usually result in crossbreeding failing or offspring?infertility in kiwifruit crossbreeding,so ploidy test would be one of the prerequisites for selecting crossing parents. But so far the chromosome ploidy of quite a number of species in actinidia has been poorly understood,which limits further development and utiliza?tion of these resources.In this study,ten ploidy?unknown species of Actinidia:A.albicalyx,A.cylindrica,A.diversicolo-ra,A. linguiensis,A. indochinensis Merr. var. ovatifolia,A. persicina,A. wantianensis,A. longicarpa,A. rongshuiensis and A. pentapetala were studied for their chromosome ploidy with acid hydrolysis method,as most of the ten species are Guangxi endemic harboring unique and excellent horticultural traits and possess great production and development value.The results showed that all of the ten species were diploid(2n=2x=58).The findings expand the genetic diversi?ty database of Actinidia and provide information for the further rational development and utilization of these resources.关键词
