我国南方松树杂交育种研究进展及发展趋势

经过近 30年的努力 ,广东、广西松树杂交育种和引种方面取得了较为显著的成果。选育的 PEE× PCC F1具有母本湿地松的树干通直圆满、抗风力强、分枝习性好、耐水渍和父本加勒比松的速生、树皮薄等优点。除适应性广 ,材质好外 ,其遗传增益比亲本增加 30 %以上。本文详细介绍我国南方松树杂交育种研究进展状况 ,阐明了杂交松研究今后的发展趋势

Advance and Development Trends of Hybrid Breeding in South China

With over 30 years of work, Guangdong and Guangxi have made great achievement in hybrid breeding and introduction of hybrid pines. During the introduction process of Pinus elliottii and P.caribaea. it was found the PEE and PCC had some complementary traits. PEE was more wind firm , straight,and more tolerant of poor drainage, while PCC had faster growth and uniform wood quality. The study advances of pine hybrid breeding was reviewd in this paper. It stated developmental trends of hybrid pine in the future.
