摘要：参试材料为美洲黑杨50号(母本)和5个种源(各10个单株)青杨(父本)杂交获得的25个家系115个子代无性系。5年生生长性状的方差分析结果表明,子代无性系在父本不同种源间、种源内家系间和家系内无性系间3个不同水平上存在α=0 001水平的显著差异,具有较大选择潜力。根据子代无性系的生长量和水泡溃疡病抗性,初步选择出了36个生长量大且对水泡溃疡病有一定抗性的优良无性系。
The controlled hybridization between a female Popupus deltoides Marsh.'55/65' and 5 provenances (10 individuals each provenances) of the male P.cathayana produced the hybridization system with multile-level variations for breeding with F_1 clones.For 5 years after planted in plantation,115 clones of 25 families were experimented.The growth traits,including height,diameter at breast height and volume,of F_1 hybrid clones and their different resistance ability to Dothiorella gregaria (poplar canker) were analyzed.The analysis of variance showed that among F_1 hybrid clones,the significant differences of 5-year-old growth traits existed among clones of male-parent P.cathayana from 5 provenances,among families within 5 male-parent provenances and among clones within families.The significant difference of 5-year-old growth among F_1 clones showed that the selection potential was greater among F_1 clones.On base of growth traits and resistance to D. gregaria,36 super clones were selected and used for multi-traits selection in future.
