同异联系势分析法在马铃薯区试综合评价中的应用

Application on Similarity-Difference Connection Trend for Comprehensive Evaluation of the Potato Variety Regional Trial

为克服传统马铃薯品种评价的局限性,应用同异联系势分析方法对2019年湖北省马铃薯品种(系)区域试验结果进行综合分析,并对参试品种优劣进行评估。结果表明,参试品种华薯6号、08HB18-4和鄂马铃薯17与理想品种的联系度分别为0.8843、0.7645、0.7443,综合表现优良,可考虑示范推广;其余品种表现良好,需进一步试验观察。同异联系势分析法可以用于综合评价马铃薯区域性试验中品种的丰产性和稳产性,能够比较全面准确地判断品种的优劣。

In order to overcome the limitation of traditional potato variety evaluation method,the comprehensive evaluation on potato varieties from Hubei potato variety regional test in 2019 was analyzed comprehensive by means of identical and different method.The result showed that the connection degree between 3 potato variety(Huashu6,08HB18-4 and Emalingshu17)was 0.8843,0.7645,0.7443,respectively.The comprehensive traits were excellent,so these varieties should be demonstrated and popularized.The other potato variety need to be observed and tested further.The analysis of similarity-difference connection trend could estimate the yield productivity and stability simultaneously.It could determine the advantage and disadvantage of potato variety comprehensively and accurately.
