为寻找高产、养分利用效率高、适应性广的花生优良品种，在河北省低香槟区和山前平原区选种了19个花生品种。采用主成分分析方法，通过比较19个品种的生物量和养分等16个主要性状，评价其对不同生态区的适应性。根据主成分临界值（>1.0），将16个生物量和养分特征整合为4个主成分，占原始信息的85%。结果表明，不同生态区花生品种在产量和养分利用效率上存在明显差异。将19个花生品种按生态适应性分为2类，适应性较广的品种按产量和养分利用效率进一步分为3类。结果表明，育花9719、吉花0212-4、卫花10号、育花15号、普花28号和吉花10号具有高产、养分利用效率高、适应性广等特点。
To identify the good peanut cultivars with the properties of high yield, high nutrient use efficiency and wide adaptability, 19 selected peanut cultivars were planted in the low champaign area and piedmont plain area of Hebei Province. By using principal component analysis, the adaptability of these 19 cultivars was evaluated for different ecological regions through comparing their 16 main traits including biomass and nutrient parameters. According to the critical value of principal component (>1.0), the 16 biomass and nutrient characteristics were integrated into 4 principal components which accounted for 85% of the original information. The results indicated that there were obvious differences in yield and nutrient use efficiency for the peanut cultivars in different ecological regions. The 19 peanut cultivars were classified into 2 groups according to their ecological adaptability, and the cultivars from the group with wide adaptability could further be divided into 3 categories according to their yield and nutrient use efficiency. Among these cultivars, Yuhua 9719, Jihua 0212-4, Weihua 10, Yuhua 15, Puhua 28 and Jihua 10 were selected as the better peanut cultivars with the properties of high yield, high nutrient use efficiency and wide adaptability.
