摘 要
为满足林业生产对高产优质树种的需求，本研究以三种主要经济树种为对象，通过对其良种产量和品质的系统对比分析，探讨不同树种在遗传改良中的潜力与差异。研究选取了A、B、C三个树种的多个代表性良种，采用田间试验与实验室检测相结合的方法，从生长指标、产量性状及品质参数等方面进行综合评估。结果表明，不同树种间的产量和品质存在显著差异，其中树种A表现出较高的产量优势，而树种B则在品质性状上更具竞争力。此外，树种C展现出良好的适应性和稳定性，具有较大的改良潜力。本研究创新性地引入多维度评价体系，结合分子标记技术对良种特性进行精准解析，为树种选择和育种策略优化提供了科学依据。研究成果不仅填补了相关领域系统性对比研究的空白，还为推动林业良种化进程和可持续发展提供了重要参考。

Abstract
To meet the demand for high-yield and high-quality tree species in forestry production, this study focused on three major economic tree species, conducting a systematic comparative analysis of their superior varieties in terms of yield and quality to explore the potential and differences in genetic improvement among different species. Multiple representative superior varieties of species A, B, and C were selected, and a combination of field experiments and laboratory tests was employed to comprehensively evaluate growth indicators, yield traits, and quality parameters. The results showed significant differences in yield and quality among the tree species, with species A demonstrating a higher yield advantage and species B exhibiting greater competitiveness in quality traits. Additionally, species C displayed excellent adaptability and stability, indicating substantial potential for improvement. This study innovatively introduced a multi-dimensional evaluation system and integrated molecular marker technology to precisely analyze the characteristics of superior varieties, providing a scientific basis for tree species selection and breeding strategy optimization. The research not only fills the gap in systematic comparative studies in the relevant field but also offers important references for promoting the advancement of superior forestry varieties and sustainable development.
