摘要： 转座插入突变体mf1表现为一个小穗内着生两朵以上小花。以该突变材料为切入点，将水稻幼穗分化发育、小穗形态结构观察、遗传分析和PCR检测等实验内容相结合，设计一个遗传学综合性实验。通过融合线上虚拟仿真实验与线下实操学习，学生能更加直观了解水稻的幼穗分化发育过程，理解转座因子的概念和应用、理清野生型与突变体、表型与基因型的关系、学会植物显微制片技术、PCR检测技术和方差分析方法，对培养学生多专业知识综合运用能力和科学研究能力有着重要实践意义。

Abstract: Transposable insertion mutantmf1shows more than two florets in one spikelet. Taking this mutant material as the starting point, a comprehensive genetic experiment was designed by combining the experimental contents of observation of rice young panicle differentiation and development, examination of spikelet morphological structure, genetic analysis and PCR detection. Through the integration of online virtual simulation experiment and offline practical learning, students can more intuitively understand the process of rice young panicle differentiation and development, comprehend the concept and application of transposable factors, clarify the relationship between wild type and mutant and between phenotype and genotype, and learn techniques and methods of plant microsection, PCR detection and variance analysis. The implementation of the experiment has important practical significance for cultivating students’ comprehensive application ability of multi-disciplinary knowledge and scientific research ability.
