摘要：

目的: 研究楸树无性系在不同土壤含氮量下生物量和氮素利用效率的变异规律，结合无性系与环境互作效应相关分析，筛选可以推广的高生产力且高氮利用效率的优良无性系，为楸树养分资源高效无性系的选择和应用提供理论依据。方法: 以3个试验地点6年生13个楸树无性系为研究对象，利用异速生长模型计算其生物量，通过对氮含量的测定，计算氮素利用效率，并对无性系的变异规律进行分析。利用ASReml-R程序包拟合混合效应模型，得到3个试验地点13个楸树无性系生物量与氮素利用效率的 BLUP 数据，使用可视化BLUP-GGE 双标图对其进行适应性和稳定性分析。结果: 3个试验地点土壤含氮量具有显著差异（P<0.05），由高到低依次为曹县、永城和牡丹区。不同无性系的生物量、氮素利用效率在同一地点具有极显著差异（P<0.01），同一无性系的生物量、氮素利用效率在不同地点也具有极显著差异（P<0.01），对2个指标分别进行排序，发现无性系6-7、008-1、1-3和2-8的生物量在3个试验地点均较高，无性系8401、6-7、2-8和20-01的氮素利用效率在3个试验地点均较高。对不同无性系的适应性分析发现，无性系2-8在牡丹区和曹县地点适应性最强，无性系1-3在永城地点适应性最强。对不同无性系高生产力与稳定性分析发现，无性系6-7和2-8为生物量与氮素利用效率较高且在3个试验地点较稳定的优良无性系；无性系1-3为生物量与氮素利用效率较高但氮素利用效率稳定性一般的无性系；008-1为生物量较高但氮素利用效率较低且稳定性一般的无性系。结论: 基于不同土壤含氮量下对13个楸树无性系生物量与氮素利用效率的排序结果，结合BULP-GGE双标图中适应性、高生产力和稳定性分析，筛选出无性系6-7和2-8为生物量和氮素利用效率双高型无性系，可栽植范围较广；无性系1-3为低氮高效型无性系，可栽植在牡丹区等土壤含氮量较低的地点；无性系008-1为高氮高效型无性系，可栽植在曹县等土壤含氮量充足的地区。

Abstract:

Objective: In this study, the variation patterns of biomass and nitrogen utilization efficiency (NUE) of Catalpa bungei clones were investigated at different soil nitrogen content sites, and the interaction effects between clones and environment were analyzed to screen elite clones with high productivity and high nitrogen use efficiency. The objective is to screen superior clones with high productivity and NUE, and to provide theoretical basis for the breeding of C. bungei clones. Method: Thirteen 6-year-old C. bungei clones from three experimental sites were selected as the research materials. The biomass was calculated using an allometric growth model. Subsequently, the nitrogen content was measured, with which NUE was calculated. The ASReml-R package was used to fit a mixed effect model. The BLUP data of biomass and NUE of thirteen C. bungei clones from three experimental sites was obtained, and the visual BLUP-GGE biplots were used to analyze the adaptability and stability of these clones. Result: There was a significant (P<0.05) difference in soil nitrogen content among the three experimental sites, with a descending order of Caoxian, Yongcheng, and Mudanqu. The statistical analysis showed that there were significant (P<0.01) differences in biomass and nitrogen use efficiency among different clones at the same site, and significant (P<0.01) differences in biomass and nitrogen use efficiency of the same clone among different sites. Through sorting the two indicators separately, it was found that biomass of clones 6-7, 008-1, 1-3, and 2-8 was higher than that of the other clones in all sites, and the NUE of clones 8401, 6-7, 2-8, and 20-01 was higher than that of the other clones in all sites. The adaptability analysis of different clones showed that clone 2-8 had the strongest adaptability in the Mudanqu and Caoxian, while clone 1-3 had the strongest adaptability in Yongcheng. Clone 6-7 and clone 2-8 were superior clones with high biomass and NUE, and their performance was suitable at the three experimental sites. Clone 1-3 had relatively higher biomass and NUE, but its NUE was not high. Clone 008-1 had high biomass, but its NUE was low with low stability. Conclusion: Based on the ranking of biomass and NUE of the thirteen clones under different soil nitrogen contents, and combined with analysis of adaptability, high productivity, and stability in the BULP-GGE biplots, it is found that clone 6-7 and clone 2-8 are elite clones with high biomass and NUE, and they have good growth performance at all three sites. The clone 1-3 is a clone with high biomass and NUE at low nitrogen site, and it is suitable to be planted in Mudanqu and other sites with low soil nitrogen content. The clone 008-1 is a clone with high biomass and NUE at high nitrogen site, and it is suitable to be planted in Caoxian and other sites with high soil nitrogen content.
