摘要： 为了分析水稻DUS测试指南中标准品种在上海地区的性状表达差异，为长江下游平原丘陵地区的水稻品种审定和保护提供完善、准确的测试标准品种，通过对水稻测试指南中39份标准品种2015—2017年的田间测试试验，用符合系数对标准品种在上海地区的性状表现与水稻测试指南中的代码进行了差异性分析，并进一步对部分性状的标准品种进行了优化。结果表明，水稻测试指南中的52个测试性状中有40个性状的符合系数为1，占76.9%，数量性状的表现受环境条件的影响较大，符合系数小于1的12个性状中有10个为数量性状；水稻测试指南中的39个标准品种中有26个品种的符合系数为1，其性状表达状态非常稳定。‘广陆矮4号’的符合系数最低，‘Heuknambyeo’次之，其他品种的符合系数均大于0.99。大部分品种可以作为标准品种应用于上海地区的水稻DUS测试，并对某些性状的标准品种给予了优化。

Abstract: To analyze the trait expression differences of standard varieties for the rice (Oryza sativa) DUS testing in Shanghai area, and provide improved and accurate standard varieties for rice variety certification and protection in the plain and hilly areas of the lower reaches of Yangtze River, this study introduced the coefficient of coincidence to the rice DUS testing to analyze the differences between the real trait expressions and the codes in the rice DUS testing guideline from 39 standard varieties in the area based on field experiments from 2015 to 2017, and further optimized the standard varieties of some traits. The results showed that the coefficient of coincidence of 40 traits was 1, accounted for 76.9% of all the 52 traits in the rice DUS testing guideline. The performances of quantitative traits were greatly influenced by environmental conditions. 10 of 12 traits with the coefficient of coincidence less than 1 were quantitative traits. Among the 39 standard varieties of the rice DUS testing guideline, the coefficient of coincidence of 26 standard varieties reached 1, and the performances of their traits were very stable. The coefficient of coincidence of ‘Guangluai 4’ was the lowest, followed by that of ‘ Heuknambyeo’, and the coefficients of coincidence of the other varieties were greater than 0.99. Most varieties could be used as standard varieties for the rice DUS testing in Shanghai area, and further optimization of the standard varieties in some traits were carried out.
