【摘要】 小黑杨(Populus xiaohei T.S.Hwang ex C.Wang et Tung)花药离体培养获得单倍体植株,经14年的生长观察,发现花粉植株间表现出明显分离。选出19个株系进行田间比较试验,统计分析,结果发现材积生长差异显著。可从中选出优良株系加以利用,并提出杨树单倍体育种程序。更多还原

【Abstract】 After 14 years’ growth observation on the plant growth, it was found that obvious segregation appeared among the haploid pollen plants obtained from anther culture of Populus xiao-hei T.S. Hwany ex C. Wang et Tung in vitro. By vegetative propagation, 19 clones were selected and field contrast test was carried out. Statastical analysis result showed a significant difference in volume production. It is superior clones could be selected from among the pollen plants for utilization. A haploid breeding procedure is suggested in the paper.更多还原
