【目的】

解析红锥种子园自由授粉子代家系叶功能性状的遗传变异规律及基因型与环境互作效应（G×E），筛选出关键环境驱动因子，为红锥精准遗传改良与推广提供理论依据。

【方法】

以广西玉林、柳州和南宁3个试验点的33个5.5年生红锥自由授粉子代家系（母本源自5个地理种源）为材料，测定叶功能（形态、生理）性状，采用巢式方差、因子分析、BLUP-GGE联合分析，系统解析红锥叶功能性状遗传变异规律和G×E效应。

【结果】

1）单环境试验中，子代叶功能性状在家系水平变异更显著，呈“种源内家系间变异为主、种源间低分化”特征；叶形态、生理性状家系遗传力范围分别为0.02~0.85、0.12~0.92，具备家系选择潜力；2）多环境试验中，叶功能性状显示出显著的点位效应，且跨地点遗传力降至0.03~0.25（形态）、0.10~0.14（生理），表明G×E显著影响红锥叶形态构建和生理代谢过程，并影响生长性状和叶功能性状协同改良；3）因子分析可筛选出各试验点特异适应性优良家系，BLUP-GGE联合分析进一步识别出兼具高产、稳产的广适性优良家系；4）热量因子是驱动红锥叶功能性状空间变异的关键环境因子。

【结论】

红锥种子园自由授粉子代家系叶功能性状遗传变异主要存在于家系层次，且受G×E效应影响显著。在人工良种选育及推广中，应确立以家系选择为核心、G×E作用规律为指导的育种策略，并根据目标环境和用途精准部署特异或广适性基因型，以优化育种效率与推广效果。

【Objective】

To support the breeding of superior germplasm of Castanopsis hystrix, this study investigated the genetic variation patterns in leaf functional traits and genotype by environment (G×E) interactions among open-pollinated progeny families from C. hystrix seed orchards, with the aim of identifying key environmental drivers and providing a theoretical basis for precision breeding and effective deployment.

【Method】

The study used thirty-three 5.5-year-old open-pollinated progeny families (with female parents from five geographical provenances) from three test sites—Yulin, Liuzhou, and Nanning in Guangxi. Leaf functional traits, including morphological and physiological characteristics, were measured. Nested ANOVA, factor analysis, and BLUP-GGE joint analysis were applied to systematically assess genetic variation patterns and G×E effects on leaf functional traits.

【Result】

1) In single-environment tests, leaf functional traits exhibited significant variation at the family level, showing a pattern of “high variation among families within provenances and low differentiation between provenances.” Family heritability ranged from 0.02-0.85 for morphological traits and 0.12-0.92 for physiological traits, supporting the potential for family selection; 2) Multi-environment tests revealed significant site effects and a notable decrease in across-site heritability—0.03-0.25 for morphological and 0.10-0.14 for physiological traits—indicating a strong G×E influence on leaf development and metabolism, and its role in the coordinated improvement of growth and leaf functional traits; 3) Factor analysis identified site-specific elite families, while BLUP-GGE analysis further discerned widely adapted families with both high performance and stability. Thermal factors were identified as key environmental drivers of spatial variation in leaf functional traits.

【Conclusion】

In C. hystrix seed orchard progenies, genetic variation in leaf functional traits occurs predominantly at the family level and is significantly shaped by G×E. A family-based breeding strategy guided by G×E patterns is recommended to enhance genetic gain. Deployment of site-specific or broadly adapted genotypes according to target environments will help optimize breeding efficiency and promotion outcomes.
