| 摘 要： | 通过初级种子园双列交配设计控制授粉，进行全同胞子代测定，评选出花期相近、自交系不育、正反交子代均生长突出(材积增益30％以上)的组合建立杂交种子园。我省从457个组合的全同胞子代测定林中，评选出杂交种子因亲本9组，并在靖州、会同、江华、资兴建成种子园共200亩。杂交种子因子代14a生单株材积0．1866—0．2274m^3，大于生产种对照30．0％-58．4％，建园效益十分显著。

| Abstract: | Based on the control pollination of dual line copulation design of a seed orchard and observations on the sibling progeny generation the hybridization seed orchard was established using similar bloom period, self-bred sterility, and reciprocal cross progeny. Nine groups of parents from hybridization seed orchards were selected from 257 groups in sibling progeny of Hunan. The areas of seed orchards were 200 mu in Jingzhou, Huitong, Jianghua and Zhixi county. The single volume was 0.186?6 to 0.224?7 m~3 in 14 years as a seed orchard, and higher than the obverse group by 30.0% to 58.4%. |
