为选育油茶春花优良品种,以油茶杂交子代(YZ2×DY2)及亲本[母本(YZ2)、父本(DY2)]为研究对象,调查测定其花期和花器官性状,对花期性状进行分级,并对 9 个性状(花横径、花纵径、花柱裂数、雌蕊长、雄蕊长、花瓣数、花药数、盛花期相对时间、开花持续时间)进行变异、相关性、主成分、聚类分析.将盛花期相对时间和开花持续时间进行等距分级,筛选出符合良种选育目标的花期类型(95 株)和极长持续期类型(43 株).9 个性状变异系数为 9.75％～35.74％,其中,盛花期相对时间的变异系数最大,花柱裂数的变异系数最小.9个性状的中亲优势率范围为-23.17％～0.84％,除盛花期相对时间外均为负值,所有性状均出现超...

In this study,we aim to provide a scientific basis for breeding superior varieties of Camellia oleifera by conducting multivariate statistical analysis on the flowering period and floral organ traits of this plant.The flowering stage and floral organ traits of the hybrid offspring of C.oleifera(YZ2×DY2)and their parents[female parent(YZ2),male parent(DY2)]were investigated and measured.The flowering stage traits were graded,with nine traits(floral transverse diameter,floral longitudinal diameter,number of style divisions,pistil length,length o...
