| morphologic, molecular, and pathogenic characterization of diaporthe phaseolorum variability in the core soybean-producing area of argentina. | abstract isolates of the diaporthe/phomopsis (d/p) complex were collected in the main soybean producing area of argentina during the 1996-97, 1997-98, and 1998-99 growing seasons. twenty-three morphologic characters related to type of colonies, stroma, pycnidia and conidia, presence of perithecia, and asci length were studied by principal component analysis (pca). genomic dna were analyzed by the random amplified polymorphic dna (rapd) technique. from both studies, 18 isolates were identified as ... | 2003 | 18943127 |
