    5年生白桦杂种子代多点稳定性分析及优良家系选择

    Analysis of the stability and superiority of five-year-old birch crossbreed families based on a multi-site test.

    • 摘要: 本文以10个白桦杂种子代家系为材料,分别在辉南、凌海、丹东等3个试验点营造子代测定林,对5年生白桦树高和胸径等性状进行多地点联合分析。结果表明:树高性状在各地点间和各家系间以及家系与地点的交互作用上均达到差异显著水平(P0.05);胸径仅在地点间达到显著水平(P0.05)。辉南试验点生长较好的有201、203、204、316、318等家系;凌海试验点生长较好的有201、202、314、316、318、319等家系;丹东试验点生长较好的有202、315、318、319等家系。采用AMMI模型对参试家系的树高性状进行稳定性评价,结果显示: 203、204、318、319、316属于高产稳产型家系;201、202属于高产非稳产型家系;320、315属于低产稳产型家系;314属于低产非稳产型家系。

       

      Abstract: Multi-site forestation testing is a key step in the evaluation of stability and growth traits of tree family or clone. Tree height (H) and diameter at breast height (DBH) of ten families of five-year-old birch planted in Huinan County, Linghai and Dandong cities were measured and jointly analyzed. The results showed that differences in tree height among sites and families, and interaction between sites and families, were significant (P0.05). The differences in DBH were only significant among sites at the level P0.05. Families 201, 203, 204, 316 and 318 had excellent traits in Huinan, as did families 201, 202, 314, 316, 318 and 319 in Linghai and 202, 315, 318 and 319 in Dandong. We used AMMI model to evaluate the stability of tree height of tested families. Results indicated that families 203, 204, 318, 319 and 316 are high-yield and stable types, 201 and 202 high-yield but instable types, 320 and 315 low-yield yet stable types, and 314 low-yield and instable types. These results provide a theoretical basis for selection and a reference for the spread of birch crossbreeds.
