| 摘 要： | 为了充分发挥中国杏新品种DUS测试指南的指导作用，在测试指南研制过程中，通过调查果实纵径、果实横径、果实侧径、叶片长度、叶片宽度、叶柄长度以及衍生性状果实纵径／横径、果实侧径／横径、叶片长度／宽度、叶片长／叶柄长的变异及分布情况，确定了这些性状的分级取值区间，探讨了分级标准。为进一步制定杏DUS测试指南提供了重要依据。 |

| Abstract: | In order to improve the practicability of apricot DUS test guideline of China, the variation and distribution type of 10 quantitative characteristics including length of leaf, width of leaf, length of petiole, length of leaf/width of leaf, length of leaf/length of petiole, height of fruit, lateral width of fruit, ventral width of fruit, height of fruit/ventral width of fruit, lateral width of fruit/ventral width of fruit were studied. Based on the results, classification criteria for these quantitative characteristics was discussed and recommended. This will provide a valuable basis for compiling apricot DUS test guideline of our country. |
