采用莫惠栋、曹桂英报告的非参数统计方法对 1998年安徽省双季晚粳区试资料进行分析。结果表明 :(1)M114 8表现突出 ,产量低于和显著低于该品系的品系出现率Pi(% )和P′i 为 78% ,43%。双优 4183、晚粳 8813 19的丰产性表现优良 ,其Pi(% )和P′i 分别为 83 %、6 5 %和 34%、37%。 (2 )参试品系的产量稳定性有极显著差异。M114 8的产量稳定性最好 ,其Si=1.6 2 0 ,双优4183的产量稳定性较好 ,其Si=2 .2 86。 2个对照品系的产量稳定性表现明显不同 ,D90 5 5 (CK2 )的稳产性表现良好 ,其Si=2 .0 47,而 70优 0 4(CK1 )的产量稳定性表现却很差 ,其Si 高达 4.0 95。 (3) 7个试点分辨品种差异的能力大小顺序为 :宣城 >舒城 >旌德>合肥、安庆 >巢湖 >铜陵。铜陵的Dj值最低 ,仅为 11%。笔者还对区试资料的统计分析方法进行了讨论。
The non-parametric statistical methods reported by Mo Huidong and Cao Guiying were used to analyze the trial data of double crop late japonica rice in Anhui Province in 1998. The results showed that: (1) M114 8 showed outstanding performance, yield (P (subscript p)%) and yield (P’i) were 78% and 43% lower than and significantly lower than that of the line. Shuangyou 4183 and late japonica 8813 19 performed well with high yield, with Pi (%) and P’i being 83%, 65%, 34% and 37%, respectively. (2) There was a significant difference in the yield stability of the tested lines. The yield stability of M114 8 was the best, the yield stability of Si = 1.620, Shuangyou 4183 was better, and Si = 2.286. The yield stability of two control lines was significantly different. The yield stability of D90 5 5 (CK2) was good with Si = 2.047, but the yield stability of 70 0 0 (CK1) Si up to 4.0 95. (3) The ability of 7 pilot to distinguish between varieties of the order of magnitude: Xuancheng> Shucheng> Jingde> Hefei, Anqing> Chaohu> Tongling. Tongling Dj value of the lowest, only 11%. The author also discusses the statistical analysis methods of the district test data.
