应用灰色系统理论关联度分析法,对1993年河南省夏大豆品种区域试验参试的11个品种(系),9个主要性状进行了综合评价分析。结果表明:周S03—1、郑双交8603—1、封155三个品种关联度分别为0.7827、0.7787、0.7724居前三位,综合性状最好,属高产稳产型品种(系)。其它品种(系)关联度居中或较小,表现一般或较差。这一评价结果与品种的实际表现相一致。该方法克服了对品种单一性状评价的偏差,为合理评价和利用品种提供了科学依据。
Based on the gray system theory of correlation analysis, 11 varieties (lines) and 9 main traits of summer soybean varieties regional trial in 1993 were evaluated comprehensively. The results showed that the correlation degree of Zhou S03-1, Zheng Shuangjiao 8603-1 and Feng 155 were 0.7827, 0.7787 and 0.7724, respectively, which ranked the top three, with the best comprehensive characters, belonging to the varieties with high and stable yield. Other varieties (lines) of the relevance of the middle or smaller, the performance of general or poor. The result of this evaluation is consistent with the actual performance of the breed. The method overcomes the deviation of the evaluation of single traits of cultivars and provides a scientific basis for the reasonable evaluation and utilization of cultivars.
