美洲黑杨杂交无性系苗期性状联合选择
Combined Selection of Hybrid Clones of Populus deltoids at the Seedling Stage
摘要
Abstract
In order to acquire the fast-growing and disease-resistant poplar varieties,we used superior South America black poplar varieties as parents to make six different crosses and applied the one-year-old progeny seedlings of six hybrids as materials to culture their clones,and then the growth status of the clones at their seedling stage and their rust disease index were determined.The measurements indicated that the families of HB-Ⅳ,HB-Ⅵ and HB-Ⅰ showed strong advantages in the seedling height and basal diameter;the families of HB-Ⅰ and HB-Ⅳ showed strong advantage in disease resistance to rust.Considering the growth and disease resistance traits at the seedling stage of hybrids clones,we selected 14 resistant plants with excellent heterosis from Family HB-Ⅰ at last,and this laid a good foundation for further breeding excellent varieties with the character of fast-growing,high disease resistance and reproductive capacity.关键词
