应用灰色系统理论对向日葵品种进行综合评价

目的]对向日葵杂交组合进行优劣评价,为新品种的示范和推广提供科学依据.方法]应用灰色系统理论分析方法,对2009年配置的10个向日葵杂交组合,通过8个主要经济和农艺性状进行分析对比.结果]灰色系统理论的分析方法与以产量为基础的方差分析结果基本一致,10个向日葵杂交组合的关联度排序依次为,X6(9K192) > X8(9K200) > X7(9K197) > X5(9K186) > X9(9K203) > X4(9K170) > X10(9K220) > X3(9K120) > X1(9K076) > X2(9K117).结论]参试的10个杂交组合中以9K192(X6)、9K200(X8)和9K197(X7)的主要性状表现最优越,与参考品种最接近,可作为生产性组合适当的配置使用.

Comprehensive Evaluation of Sunflower Varieties by Using the Theory of Gray System

【Objective】To evaluate the sunflower hybrid combinations and provide scientific basis for new varieties demonstration and extension.【Method】Using gray system theory analysis method,8 main economic and agronomic traits of the 10 sunflower hybrid combinations configured in 2009 were analyzed and contrasted.【Result】Results showed:gray system theory analysis method and the output based variance analysis result basically was consistent,the correlation degree of the 10 sunflower hybrid combinations were X6(9K192) > X8(9K200) > X7(9K197) > X5(9K186) > X9(9K203) > X4(9K170) > X10(9K220) > X3(9K120) > X1(9K076) > X2(9K117).【Conclusion】Among the 10 tested hybrid combinations,the main characters of 9K192(X6),9K200(X8) and 9K197(X7) were the most superior,and is the closest to the reference varieties and could be used as production combination after proper configuration.
