摘要： 以2005年河北省稻作研究所育成的11个水稻新品系为试验材料，应用灰色关系统理论的关联分析法，对其产量、生育期、株高等10个农艺经济性状指标进行综合评价与定量分析，结果表明，优2和优1关联度大，与参考种最接近，综合性状最好，具有生育期适中、穗大粒多、产量高、抗性强等特点；关联度最小的为412，实际表现最差。结果分析指出，依据关联序所做的评价结果与该品系的实际表现相一致

Abstract: Eleven new rice varieties were wholly evaluated By using the Grey Correlative Degree Analysis in 2005 in Rice Research Institute of Hebei province. They were analyzed in terms of 10 varying characters including yields, growth period, plant height. The comprehensive evaluation results showed that You 2 and You 1 ranked first, and its comprehensive characters were best, they have many advantages: good growth period, bigger ear, higher yields, resistance disease. The worst one was 412, and the Correlative Degree was lowest. It point out that the appraisal consequence was fundamentally in conformity with the practical performance of the varieties
