摘要：

早春低温主要发生在萌发期和幼苗期2个阶段, 是限制我国东北地区花生产量和品质的关键性因素。在农业生产上, 耐冷品种的选育是解决低温冷害问题最直接有效的手段。本研究以68个东北地区主栽的花生品种为试验材料, 分别在室内萌发期、幼苗期及田间对其耐冷性进行了评价。在萌发期, 通过对10℃、8℃、6℃和4℃处理7 d后各花生品种的种子活力进行综合隶属函数分析和标准正态分布检测发现, 6℃处理7 d适合作为大批量花生种质耐冷性鉴定的条件。在幼苗期, 经6℃处理7 d后, 以株高、叶面积、地上部鲜重、地下部鲜重、地上部干重、地下部干重和耐冷等级作为评价指标, 对各花生品种的耐冷性进行鉴定。相关性分析表明, 叶面积、地上部鲜重和耐冷等级与花生的耐冷性关系最为密切, 可以作为花生苗期耐冷性鉴定的主要评价指标。在田间自然条件下, 采用提前播期和分期播种的方式, 以相对出苗率、相对出苗能力及产量构成因素为评价指标对室内筛选结果进行验证, 基于多重表型分析方法, 最终鉴定出适合东北地区种植的在萌发期和幼苗期均耐冷的花生品种农花5号, 以及冷敏感型花生品种阜花18号。本研究为我国高寒地区的花生种植提供了品种参考, 为花生耐冷机制研究提供了优异种质资源。

Abstract:

Low temperature in early spring is the key factor limiting the yield and quality of peanut in Northeast China, which mainly occurs at germination and seedling stages. The selection and breeding of cold-tolerant cultivars are the most direct and effective means to solve the problem of chilling injury in agricultural production. In this study, 68 peanut cultivars mainly planted in Northeast China were used as experimental materials, and their cold tolerance was evaluated at germination and seedling stages in the climatic chamber and field, respectively. At germination stage, we found that the cold treatment at 6℃ for seven days could be the suitable condition for cold tolerance evaluation of large-scale peanut germplasm by the comprehensive membership function analysis and the standard normal distribution test according to the seed vigor of peanut cultivars after treatments at 10℃, 8℃, 6℃, and 4℃ for seven days. At seedling stage, after treatment at 6℃ for seven days, plant height, leaf area, fresh weight of aerial parts, fresh weight of root, dry weight of aerial parts, dry weight of root, and cold tolerance grade were measured to evaluate the cold tolerance of various peanut cultivars. Correlation analysis revealed that the leaf area, fresh weight of aerial parts and cold tolerance grade had the most significant relationships with cold tolerance and could be used as the main evaluation indicators for the identification of cold tolerance at seedling stage in peanut. In the field, cold tolerance of various cultivars were evaluated by emergence rate, emergence ability, and yield component factors through the early sowing and sowing by stages. Finally, based on the multiple phenotypic analysis, the most cold-tolerant peanut (cultivar NH5) and the most cold-sensitive peanut (cultivar FH18) were identified at germination and seedling stages, suitable for planting in Northeast China. This study provided the reference for peanut planting in high-latitude and cold regions and the excellent germplasm of cold tolerance mechanism in peanut.

Key words: peanut, cold tolerance, comprehensive evaluation, screening for germplasm resources
