应用秩次变量nij和n′ij,非参数统计量Pi、P′i、Si 和Dj,对 2 0 0 0年毕节地区杂交玉米坡地组区试资料的基本特征进行描述 ,并对参试品种进行综合评判。结果表明 ,玉米区试品种间丰产性和稳定性存在显著差异 ,S2 1 9是丰产性最佳品种 ;稳定性较好的品种有赫单 4号、毕玉35 0 6、毕 2 0 0 1 ,以赫单 4号最佳 ;丰产性和稳定性均优良的品种有毕玉 35 0 6、毕 2 0 0 1。全部试点均对品种差异具有较高鉴别力 ,其中鉴别力最高的是毕节市汾河试点 ,发现了 80 6%的差数为显著
Using the rank variables nij and n’ij and the non-parametric statistics Pi, P’i, Si and Dj, the basic characteristics of regional trial data on hybrid corn slopeland in Bijie Prefecture in 2000 were described, Comprehensive evaluation. The results showed that there was a significant difference in yield and stability between varieties of maize, S2 1 9 was the best variety with high yield, and varieties with better stability were Hedan No.4, Biyu 35 0 6, Bi 2 0 0 1 , The best in Hedan No.4; the varieties with excellent yield and stability are Biyu 35 0 6, Bi 2 0 0 1. All the pilots had higher discriminative power for variety differences. Among them, the highest discriminatory power was Fenhe pilot project in Bijie City, where 80.6% of the difference was significant
