Haploid breeding ofpopulus

Abstract

After 14 year’s growth observation on the plant growth, it was found that obvious segregation appeared among the haploid pollen plants obtained from anther culture ofPopulus Xiaohei T.S. Hwany ex C. Wang et Tung in vitro. By vegetative propagation, 19 clones were selected and field contrast test was carried out. Statistical analysis result showed a significant difference in volume production. They are superior clones which could be selected from among the pollen plants for utilization. A haploid breeding procedure is suggested in the paper.
