| 摘 要： | 为了充分发挥我国玉米新品种DUS测试指南的指导作用,在实际的测试工作当中,通过调查玉米雄穗最低位侧枝以上主轴长度、雄穗一级侧枝长度、株高及穗位等数量性状,同时借助计算机和概率理论对这些数量性状的品种间变异和分布特征进行分析,确定了性状的分布区间,为在不同生态区域进行玉米新品种DUS测试,确定数量性状分级标准,提供参考。

| Abstract: | In order to improve the practicability of maize DUS test guideline in China,while doing the practical testing work,the variation and distribution type of 9 quantitative characteristics including the tassel length of main axis above lowest side branch,tassel length of main axis above upper side branch,tassel length of side branches,plant height and so on were studied with the help of the computer and probability theory.Meantime,the probability distribution was discussed and recommended.This will supply certain theoretical basis for different eeotype in doing DUS testing of new maize varieties. |
