烟草区试中品种丰产稳定性分析方法探讨

采用2011年陕西省烟草区域试验的数据资料,通过与烟草上常用方法比较,探讨Francis-Kannen-berg模型分析法、适定性参数法和高稳系数法在烟草区试丰产稳定性评价方面的可靠性与适用性。结果表明,Francis-Kannenberg模型分析法和适定性参数法计算简便,结果可靠,可以对烟草品种丰产稳定性进行基本的评价;高稳系数法受产量影响较大,不可以单独对烟草品种丰产稳定性进行评价。同时分析结果表明,在参试品种中丰产稳定性最好的品种为秦烟96和YN105。

Study on Method of High and Stable Yield in Tobacco Regional Test

Based on the experiment data of shaanxi tobacco regional test in 2011, and compared with tobacco conventional methods, this paper analyzed the reliability and applicability of Francis-Kannenberg model method, adaptable and stable parameter method and High-stably yielding coefficient method in evaluation about high and stable yield of tobacco regional test. The results showed that the method of Francis-Kannenberg model and adaptable and stable parameter, which have easy calculation and reliable results, could basically evaluate the high and stable yield of tobacco variety; the method of High-stably yielding coefficient, which was affected greatly by yield, could not individually evaluate the high and stable yield of tobacco variety. The results also indicated that Qinyan96 and YN105 were the highest and stable yield in the tested varieties.
