摘　　要：从育种材料评价的实用性出发并结合实例分析 ,探讨 4种多性状综合评价方法的评价效果及合理性。从育种学意义的明确性、直观性和计算方法的简便性、合理性全面衡量 ,综合接近度 (S .ci)分析法优于灰色关联度 (Y0i)、优良度 (Ri)和DTOPSIS相对接近度 (Ci)Four statistic methods for comprehensively evaluating multiple characters in peanut varieties were discussed with special emphasis on their practicability in breeding. It was indicated from the results that the integrated similarity degree (S.c i) was more desirable compared to the gray relation degree (Y 0i ), favorable degree (R i) and DTOPSIS relative approach degree (C i) in terms of clearness, conciseness in breeding selection and reasonableness in calculation.
