为给‘晋稻12 号’在山西水稻生产中更好地推广提供依据，根据2007—2008 年山西省水稻中晚熟组区试资料，利用DPS数据处理系统中品种区域试验统计分析的方法，对它进行了丰产性和稳产性分析。结果表明：‘晋稻12 号’2 年区试平均产量分别为9507 kg/hm2和9604.5 kg/hm2，分别比对照‘晋稻8 号’增产6%和9.8%。‘晋稻12 号’2年主效应分别为0.78 和0.71，说明该品种丰产性好；回归系数分别为1.06 和0.87，说明对环境反应不敏感；高稳系数2 年分别为13.85%和10.15%，说明该品种稳产性较 好。穗粒数、结实率、穗长的变异系数均低于对照。由此得出，‘晋稻12 号’是一个丰产稳产性高、适应性强的中晚熟水稻新品种，具有较好的广适性，米质优良，在环境条件和栽培技术好的地方种植产量潜力更大，适宜进行产业化推广。

In order to provide basis for the better spread of‘Jindao 12’in the rice production in Shanxi Province and on the basis of 2007-2008 middle and late-maturing rice trial data in Shanxi, we made analysis on the high and stable yield of‘Jindao 12’by using the method of statistical analysis of regional data in the DPS data processing systems. The results showed that: the average yields of‘Jindao 12’over these two years were 9507 kg/hm2 and 9604.5 kg/hm2, which was 6% and 9.8% more compared to‘Jindao 8’. The main effects over the above two years were 0.78 and 0.71 respectively, indicating the high yield of‘Jindao 12’; its regression coefficients were 1.06 and 0.87 respectively, indicating that it was not sensitive to the environment; its high stability coefficients were 13.85% and 10.15% respectively in the above two years, indicating its stable and good yields. The panicles, the seed setting rates and the variation coefficients of ear length were better than its comparative groups. In conclusion,‘Jindao 12’is a new type of middle and late-maturing rice with high yield stability and with strong and wide adaptability. It has good grain quality and has better potentials if it is planted in better environment and with good cultivation techniques. It is suitable for industrial promotions.
