运用灰色系统理论中的关联分析法 ,对 10个玉米杂交种从丰产性、稳产性、抗倒性、抗病性和早熟性五方面进行综合分析和评价。结果表明 :加权关联度大小顺序依次为新玉 8号 >中南 8号 >八农 70 6 >新玉 7号 >西玉 3号 =6 5 2 / 2_14>91784>金 0 3/大 40 44 >八农 70 8>八农 70 5。新玉 8号在各参试杂交种中表现最佳、其次为中南 8号、八农 70 6、新玉 7号
Based on the gray system theory, the correlation analysis method was used to comprehensively analyze and evaluate the ten maize hybrids from five aspects: high yield, stable yield, lodging resistance, disease resistance and early maturity. The results showed that the order of the weighted correlations was Xinyu 8> Zhongnan 8> Bailong 70 6> Xinyu 7> Xiyu 3 = 6 5 2 / 2_14> 91784> Jin 0 3 / large 40 44> Eight Farmers 70 8> Eight Farmers 70 5. Xinyu 8 showed the best performance among the tested hybrids, followed by Zhongnan 8, Bailong 70 6 and Xinyu 7
