| 摘 要： | 利用中长期滚动式品种比较试验非平衡数据资料的秩次分析法,研究四川省1998～1999年杂交玉米区域试验产量性状资料,对各试验环境进行常规方差分析,并定义三个统计数:平均分级值H(1Mi)、产量秩次值H(2Mi)、环境区分指数Y(M)。结果表明:在参试的12个品种中2738、SAU97-1、78599/200H、雅941这4个属于高产稳产性强的品种;秩次分析法较经典方法更全面、更合理,具有较高的应用价值。

| Abstract: | The rank analysis method about non-balance data in mid-long run regional trials that the varieties and test locations varied frequently was used to study on the yield character of maize regional trials during 1998-1999 in Sichuan.There were three statistical parameters: grade numerals of average(H1Mi),rank numerals(H2Mi) and circumstance differentiating index(YM) respectively.The results showed that maize hybrids 2738,78599/200H,SAU97-1,Ya941 have high yield and stability.The rank method were more various and reasonable and utility significance than the older statistics. |
