Abstract：Morphological observation and sequence analysis of EF-1α of tested Fusarium strains
collected from the Solanaceae crops soil in western Henan Province were carried out to clarify the species
diversity and phylogenetic relationships among Fusarium strains．The results showed that 5 branches
of Fusarium were identified in the phylogenetic tree，namely F. oxysporum，F. fujikuroi，F. verticillioide，
F. incarnatum and F.incarnatum-equiseti species complex. Among them，F. oxysporum had the
highest separation frequency of 45.83%，and was distributed in all investigated 4 kinds of Solanaceae
crops soil．While，the separation frequency of F.incarnatum-equiseti species complex was the lowest，
it only existed in potato and tomato soils．In addition，species diversity existed in Fusarium strains
from different regions and different Solanaceae crops soil．
