[Objective] Based on the cotton variety high yielding potential, fiber quality traits, disease resistance, and early maturity characters, a cultivar registration index model was developed to simplify the tedious calculation process in national cotton registration procedure, and thus to enhance the practical application of cultivar regis- tration index in cotton breeding ancl cotton recommending. [Method] By means of correlation analysis, partial correlation analysis and path analysis methods, the cor- relation of cotton main properties and their effects on cultivar registration index were explored using the dataset of national cotton regional trials in Yangtze River Valley during 1996-2013. The cultivar registration index model was constructed with step- wise regression statistical technique to ascertain the quantitative relationship of main characters with cultivar registration index, and the regional cotton trial dataset in 2013 was used to validate the model. [Result] Several characters with larger deter- minants to cultivar registration index were screened out,ie. lint yield increase ratio, pro-frost yield ratio, verticillium wilt index, fiber strength, fusarium wilt index and mi- cronaire value. The cultivar registration index model defined the functional relation- ship of cultivar registration index with the selected main characters, among which lint yield increase ratio, fiber strength and micronaire value contributed most to culti- var registration index. The model validation with regional cotton trials in 2013 indi- cated the root mean square error, RMSE was only 2.77, and the variation coeffi- cient was 6.77%, which confirmed the model prediction effect was quite perfect. [Conclusion] The developed cultivar registration index model was reliable enough to simulate the complicated scoring system in cultivar registration procedure, also sim- plified cotton registration process, and enhanced the practicability of the cultivar reg- istration index. 展开更多

小学教育专业的培养对象是小学教师。小学教育专业经历了4次嬗变:从初级师范学堂到规范的中等师范教育;中等师范学校举办五年制专科教师教育;正式出现"小学教育"专业名称的本科教师教育;"小学教育"教育硕士的专业... 小学教育专业的培养对象是小学教师。小学教育专业经历了4次嬗变:从初级师范学堂到规范的中等师范教育;中等师范学校举办五年制专科教师教育;正式出现"小学教育"专业名称的本科教师教育;"小学教育"教育硕士的专业学位教育。小学教育专业4次嬗变的内在发展逻辑在于国家对小学教师的需要从数量满足到质量追求,小学教师培养模式从封闭到开放的变革,小学教师职前职后教育一体化的专业发展。提升小学教师质量是小学教育专业发展的永恒动力。 展开更多
