Development of resistant cultivars is suggested as one of the effective control measures against the disease, however, this should be accompanied with the</span></p><p class="MsoNormal" style="text-align: left; text-indent: 0in; margin: 0in 0in 0pt; mso-layout-grid-align: none;" align="left"><span style="font-family: "Times New Roman","serif"; color: #231f20; font-size: 12pt; mso-no-proof: no;">better understanding of the pathogen’s population dynamics. This study was performed to investigate the population structure of <em>F. oxysporum </em>f. sp. <em>cepae </em>based on vegetative compatibility groupings (VCGs). Vegetative compatibility groups of <em>F.oxysporum </em>f. sp. <em>cepae </em>were characterized using nitrate non-utilizing (<em>nit</em>) mutants. Four VCGs and 2 single self-compatible (SSC) isolates were identified among 48 isolates, designated as VCG 0420 (33 isolates), 0421 (9 isolates), 0422 (2 isolates), 0423 (2 isolates), and 042-(2 isolates). VCG 0420, to which 4 ATCC isolates out of 6 belonged, was the predominant group within the growing region encompassing Hokkaido Japan. VCGs 0421 and artificial VCG 042- were found less frequently. Four isolates from Welsh onion were not compatible with any recovered VCGs and were assigned to 2 distinct VCGs (VCG 0422 and 0423).</span><span style="font-family: "Times New Roman","serif"; font-size: 12pt;"></span></p>}, number={1}, journal={Microbiology Indonesia}, author={WIDODO, . and KONDO, NORIO and KOBAYASHI, KIROKU and OGOSHI, AKIRA}, year={2010}, month={Mar.}, pages={8} }
