摘要
用美洲黑杨作亲本进行有性杂交,以抗溃疡病(Dothiorella gregaria)为选育的主要目标,兼顾生长特性、抗旱、抗寒等性状,筛选出3个优良的杨树无性系—Ⅰ—69杨×美洲黑杨的57号杨和65号杨;Ⅰ—69杨×青杨的1145号杨。
Three canker resistant clones of poplars, i. e. No. 57 [I-69 (Populus deltoides cv 'Lux' )×P. deltoides], No. 65 (I-69×P. deltoides) , and No. 1145 (1-69 x P. cathayana) were screened through clonal selective breeding by using P. deltoidet as parent material.
