A SINGLE MATING POPULATION OF GIBBERELLA-FUJIKUROI (FUSARIUM-PROLIFERATUM) PREDOMINATES IN ASPARAGUS FIELDS IN CONNECTICUT, MASSACHUSETTS, AND MICHIGAN
Wh. Elmer, A SINGLE MATING POPULATION OF GIBBERELLA-FUJIKUROI (FUSARIUM-PROLIFERATUM) PREDOMINATES IN ASPARAGUS FIELDS IN CONNECTICUT, MASSACHUSETTS, AND MICHIGAN, Mycologia, 87(1), 1995, pp. 68-71
Over 250 monosporic isolates of Fusarium spp. that belong to the Fusar
ium section Liseola were isolated from asparagus stems and from adult
asparagus beetles in seven asparagus fields in Connecticut, one in Mas
sachusetts, and one in Michigan. Sexual compatibility pairings with st
andard tester strains from six (A-F) distinct mating populations of Gi
bberella fujikuroi revealed that 238 out of 253 isolates (94%) could b
e assigned to the ''D'' population of G. fujikuroi (anamorph = F. prol
iferatum). The remaining 15 isolates were identified as F. proliferatu
m but could not be assigned to any mating population. This is the firs
t report of isolates in the ''D'' populations of G. fujikuroi predomin
ating in a host/pathogen complex.
