不同品种(系)饲草高粱国家区域试验分析

Analysis on Different Forage Sorghum Varieties in Regional Trial

采用非参数统计分析方法对2005—2006年国家饲草高粱区域试验参试品种(系)的试验结果进行了分析。结果表明:除苏波丹外,其他品种均比较适宜在全国各区试点所在地区种植。7个不同生态类型的饲草高粱品种(系)的产量不是有规律地变化,具有不同的生态特征。不同生态区组间引种、引用时应对引种地区的气候、栽培技术和本地的条件进行比较,以便确定引种饲草高粱的范围,达到有效利用。用传统的多因素随机区组设计和多年多点品种区域试验的非参数统计分析方法来度量2005—2006年全国高粱区试饲草组区试资料的区域适应性(稳产性)、丰产性及试验地点对品种差异的分辨力等进行了客观评价,该统计分析方法直观,意义明确,计算简便,值得借鉴、学习、推广使用。

Non-parameter statistics method was adopted to analyze and evaluate the result of every variety of the regional trial of forage sorghum breeding varieties of China from 2005 to 2006. The results indicated that all the varieties except Superdan were adapted to plant in the national wide of experimental units. The yield varied irregularly in seven different varieties districts with different ecological characteristics.In order to utilize efficiently and confirm the scope of varieties to introduce the climate and cultural conditions in different ecological regions should be compared before the forage sorghum varieties introduction. The stability and adaptability, productivity and differentiation of trial sites to variety diversity were valued impersonally by classical statistic methods of multivariate completely random and randomized blocks test and the basic therapy and method of nonparametrie statistics, it showed that the non-parameter statistics was simple, definite and easy to compute, and it was worthy to reference and introduce.
