Abstract
Three populations of Pratylenchus sp. were isolated by modified Baermann funnel method from the rhizosphere soil which was sampled at three different corn plantations in Taiwan since October, 2007. According to the data of the morphology, morphometrics and ribosomal DNA fragment sequences (including full 5.8S gene, ITS-1, ITS-2 and partial 18S and 28S gene), the 3 populations of nematode was identified as P. zeae Graham, 1951. This discovery was the first report in Taiwan. The representative sequence of rDNA fragment of P. zeae was submitted firstly to GenBank. The length of rDNA fragment was 967 bp included 321 bp for ITS-1, 192 bp for ITS-2 and157 bp for 5.8S.
