The present invention relates to a method for rapid detection of upland rice cyst nematode LAMP. Through the comparison of upland rice cyst nematode ribosomal rDNA ITS sequences, specific loci, selected 5 LAMP primers of HE F3, HE B3, HE FIP, HE BIP and HE LB. The method of extracting rice cyst nematode genome DNA, amplified by loop mediated isothermal amplification products, the color and observation, and rapid detection and identification of rice cyst nematode, can detect rice cyst nematode specific from 14 species of plant nematodes in 22 groups, the detection threshold value of 1/20000 capsule the sensitivity is better than the general PCR method is 10 times higher. The detection method of the invention has strong specificity, high sensitivity, simple operation, fast and efficient, the results can be visually observed, and has high application value in Upland Rice cyst nematode rapid detection and early diagnosis and field.

技术介绍
旱稻孢囊线虫(Heteroderaelachista)是一种主要侵染水稻的植物寄生线虫,最早于日本枥木县的稻田中被发现(OhshimaY.Heteroderaelachistansp.anuplandricecystnematodefromJapan[J].JapaneseJournalofNematology,1974(4):51-56.)。目前该线虫病害在湖南省多个县(市)丘陵地带的水稻田首次发现(DingZ,NamphuengJ,HeXF.FirstreportofthecystNematode(Heteroderaelachista)onriceinHunanprovince,China[J].PlantDisease,2012,96(1):151)。旱稻孢囊线虫一般寄生在寄主根部,其危害症状与水肥失调引起的症状极其相似,除吸收寄主的营养和对植物根部造成伤害外,还降低水稻对水的利用效率,继而影响寄主的生长和发育(丁中,NamphuengJ ...
