摘　　要：用品种的稳定性参数和高稳系数法分析了2002年度云南省甘蔗区域化试验的春植(新植)区试数据,同时对几个品种稳定性参数的准确性进行了比较分析。结果表明品种间回归系数的大小能较准确地反映出品种稳定性差异的程度,其对稳定性的代表性要准确于其它稳定性参数,虽然用回归系数分析法较为详细准确,但是较为繁琐。用高稳系数法分析品种高产稳产性较简单,而且结果可靠。生产实践证明,分析结果和生产实际相吻合。The regional trials data of spring planting cane in Yunnan in 2002 were analyzed with cultivars stability parameter and high stable coefficient method. The accuracy of stability parameter of several cultivars was also analyzed in the paper. The results showed that regression coefficient between cultivars can reflect the stability differences of cultivars accurately and the representativeness of its stability is accurater than other stability parameter; regression coefficient method is accurater and detailed, but miscellaneous. High stable coefficient is simple, feasible and reliable. The practice proves that the results analyzed with the method coincide with the practice.
