白杨派树种在林业生产中占有重要地位。为改良白杨树种,育出产量更高的品系,1972年以来进行了白杨派种间杂交白杨派与黑杨派间杂交,并从杂种中选育出741、303、103,106四个优良无性系原株,由原株繁殖无性系茁木。经初步品种试验,四个无性系表现优良。本文拟对杂种无性系试验进行初步分析。 Poplar tree species in forestry production occupies an important position. In order to improve the poplar tree species, yield higher yield lines, since 1972, poplar cross between poplar and black poplar crossbreed and bred from hybrids 741,303,103,106 four excellent clonal Strain, from the original plant clones Zhuo wood. After the initial variety test, four clones performed well. This paper intends to conduct a preliminary analysis of clonal hybrid experiments.
