Abstract: The regional test of maize varieties was an important link in the breeding and promotion of superior varieties, test identification results could provide detailed scientific basis for the certification and approval of maize varieties.At present,with the acceleration of the selection and breeding process of new maize varieties,a large number of new varieties passed the national and provincial certification each year,and the number of varieties tested increased year by year, leading to the working amount of test data acquisition became larger. However, the traditional data collection methods for phenotypic traits were backward,recording data taken time and effort,and data management standards were not standard,which couldn’t meet the actual needs of regional test production and management informatization of maize.A data acquisition system of maize phenotypic traits was constructed,which realized the rapid collection of maize phenotypic traits data and provided reference for the rapid acquisition of phenotypic traits information of other crops.The test results showed that,compared with manual recording method,the data acquisition system of maize phenotypic traits hand-held terminal APP could save time 70.8%,eliminated the process of photograph,data entry,professional rename,and improved the efficiency of data acquisition.The system had the characteristics of simple deployment,convenient operation,strong practicability,flexible setting and friendly interface,which could be extended to other types of crops and has a good application prospect.

摘要： 玉米品种区域试验是良种选育与推广的重要环节，试验鉴定结果可为玉米品种审定提供翔实的科学依据。目前，随着玉米新品种选育进程的加快，每年通过国审、省审的新品种数量较多，同时，参试的品种数量逐年增加，导致试验数据采集的工作量变大。而传统的表型性状数据采集手段落后、记录数据费时费力、数据管理标准不规范，已无法满足当前玉米区域试验生产管理信息化的实际需求。基于此，构建玉米表型性状数据采集系统，实现玉米表型性状数据的快速采集，为其他作物表型性状信息的快速获取提供参考。试验结果表明，与手工记录方式相比，应用玉米表型性状数据采集系统手持终端APP采集数据可节约时间70.8%，且省去了拍照、数据录入、图片重命名的过程，提高了数据获取效率。该系统具有部署简单、操作便捷、实用性强、设置灵活和界面友好等特点，可以扩展到其他类型作物，具有较好的应用前景。
