水稻两系不育系繁殖和制种安全问题，已成为制约两系法杂交稻推广应用的主要障碍。本研究基于系统评价两系杂交稻种子生产"三个安全期"的适宜气象指标，分析两用核不育系繁殖与制种生态区农田与气象站同步观测气象数据并建模，明确不育系繁殖和制种基地选择的评价标准；探索不育系繁殖制种基地和时段选择的适宜算法，建立气温变化的海拔高度模型，运用地理信息系统的空间分析方法，并将地理信息系统（GIS）集成二次开发的思想应用于可视化编程中，研制水稻两用核不育系繁殖和制种基地与时段气象决策支持系统，根据不同不育起点温度不育系对育性敏感、抽穗扬花、成熟收获三个安全期的气象指标，分析历史气象资料，从而实现水稻两用核不育系繁殖制种基地和时段的计算机智能选择。本项目的研究和应用对解决两系杂交稻制种不安全和两系不育系繁殖产量不稳、质量不高的问题和促进两系杂交水稻的健康持续发展具有重要意义。

TGMS line breeding and seed production security problems has become the main obstacle for rapid popularization and application of two-line hybrid rice. This study aiming at urgent needs and preliminary communication of TGMS line breeding and seed production safety scientific decisions, gives a systematical evaluation hybrid rice combinations evaluation system for appropriate meteorological index of two-line hybrid rice seed production "three safety periods". It analysis representative dual-purpose nuclear sterile lines breeding and breeding biota farmland and weather station synchronous observation meteorological data to make modeling, and explore its evaluation criterion; it clears located meteorological ecological diagnostic method and optimization algorithm, to apply computer processing technology and programming tools. It will apply the theory of integrated and secondary development of geographic information system in visual programming through preprocessing these years meteorological site temperatures, rainfall and humidity to build strong computer selection system for seed production base of TGMS line and which has stronger mechanism and practical applicability, then test and check out it, and realize the computer forecast for dual-purpose genic male sterile lines propagation and seed production area. The application and dissemination of the system will have great influence to two-line hybrid rice development.
