Resistance identification method for improving infection efficiency of soybean cyst nematode

The invention relates to a resistance identification method for improving the infection efficiency of soybean cyst nematode. The growth environment of soybean plants for resistance identification is effectively improved by improving the steps of culture conditions, a counting method, an inoculation method and the like, so that the number of inoculated eggs is more accurate, the infection efficiency of the eggs is improved, the data difference between different repetitions of the resistance identification results of the soybean cyst nematode is not obvious, the data is more accurate and reliable, the workload caused by repeated repetitions is reduced, and the method has great application value in the development of the resistance identification work of the soybean cyst nematode. 本发明涉及一种提高大豆胞囊线虫侵染效率的抗性鉴定方法，通过对培养条件、计数方法、接种方法等步骤的改进，有效改善了用于抗性鉴定的大豆植株的生长环境，使接种的虫卵数量更佳精确，提高了虫卵侵染效率，使得大豆胞囊线虫抗性鉴定结果不同重复间数据差异不显著、数据更准确、可靠，降低了由于需要多次重复带来的工作量，对大豆胞囊线虫抗性鉴定工作的开展有极大的应用价值。
