摘要
对参试刺槐半同胞子代优株无性系进行了３试点多年度的测定，从１６个参试系号中选出的７３０３７－２、７３０１０－１、７３００２－２、７３００２－１具有生长快、树干通直、适应性强等特点，单株材积超过对照３０％～５０％，遗传增益显著。
After permanent test on black locust good tree clones in 3 sports,four improved clones,i.e.73037-2,73010-1 and 73002-2 et al.,have been selected. They are characterized by fine stem,growing fast,stronger accommodation to natural environment. The results of 7-years measurement demonstrate that their volumes are higher than the control by 30%～50%, genetic gains both are significant.
