建国以来,洛阳市小麦良种繁育制度,一直是坚持“三年三圃制”生产原种。这一方法,在历史上曾对我市小麦良种繁育推广起到重要作用。但随着农业生产的发展和品种更换速度的加快,它已赶不上生产形势发展的需要。其弊端主要表现在:一是原种生产周期长;二是在单株选择分系比较中淘汰率高,繁殖系数低;三是耗资大,费工多;四是优中选优使群体急剧缩小,加上技术人员在选择中掌握标准不尽相同,容易导致遗传基础贫乏或性状偏移,起不到应有的增产作用。为了进一步搞好小麦种子工作,适应我市小麦生产发展形势,市种子管理站
Since the founding of the PRC, Luoyang City, wheat breeding system, has always been to adhere to the “three years three Pu system ” production of original species. This method has historically played an important role in the popularization and promotion of wheat breeding in our city. However, with the development of agricultural production and the speed of changing varieties, it has failed to meet the needs of the development of the production situation. The disadvantages are mainly manifested in the following aspects: firstly, the production cycle of the original species is long; secondly, the elimination rate is high and the multiplication coefficient is low in the comparison of single plant selection branches; thirdly, it is costly and requires more labor; Fourthly, , Coupled with technical staff in the selection of different standards to grasp, easily lead to genetic basis of poor or trait deviation, can not play due to the role of stimulation. In order to further improve the work of wheat seeds to meet the development of wheat production in our city, the city seed management station
