本研究应用抗病选种手段,以黑龙江省杨树人工林中杨树烂皮病发病率80％以上的实生林分为选优对象,从六千余公顷杨树发病林分中选出无烂皮病且生长较快的优树25株,同时将近年来杂交培育出的速生优良品种613杨、A15、A43、A100进行参试,对照树种为小黑杨、中东杨。通过对各品系后代苗的室内、圃间、林间的抗病性测试,从中选出抗病无性系014号及抗病速生良种613杨。 In this study, the selection of disease-resistant means of selection, poplar plantation in Heilongjiang Province poplar bark disease incidence of more than 80% of the selected excellent forest, from more than 6,000 hectares of poplar disease stand selected 25 rotted trees with fast growth and rapid growth. The fast growing elite varieties 613, A15, A43 and A100, which were bred by the hybridization in recent years, were also tested. The control species was Populus simonii and Populus euphratica. Through testing the offspring seedling’s indoor, inter-nursery and forest disease resistance of each line, the resistant clone 014 and resistant resistant fast growing 613 poplar were selected.
