Abstract:
During the year of 2011, the level of fungi infection with the genus Fusarium
was examined in seven genotypes of grain sorghum (Gold F1, A 28, B 28, Alba
F1, A 73, B 73, Re 236) grown in six localities: Srbobran, Futog and four
localities nearby Backi Petrovac (Backi Petrovac 1, 2, 3 and 4). The rate of
seed infection with fungus Fusarium in the investigated period ranged from 0
to 8.5%. The infection did not occur in the genotype B73 (Backi Petrovac 1),
while a low rate of infection of 0-3% was detected in the genotype B 28
(Srbobran). Medium rate of infection was recorded for the genotype A 28
(Srbobran) and A 28 (Futog) with 4.25% and for Gold F1 (Backi Petrovac 2)
with 5.5%. High rate of infection was recorded for the genotype A 73 (Futog),
A 73 (Backi Petrovac 2) (6.25%), Alba F1 (Backi Petrovac 2) (8%) and Re 236
(Futog) (8.5%). One isolate from each F. solani, F. graminearum, F.
subglutinans and F. verticilliodes was selected for the pathogenicity
investigation. Thirty plants were inoculated from each genotype of grain
sorghum (varieties Alba F1 and Gold F1) and broomcorn (var. Reform and
Prima). The spraying inoculation with the suspension of mycelium and conidia
was performed when sorghum was at the end of blooming on June 19, 2012. The
intensity of the infection on the sorghum panicles was reached in the
phenophase of milky-wax maturity on July 8, 2012 and the scale of S h a r m a
et al., (2010) was used. The symptoms of the artificial inoculation appeared
only in the broomcorn. Among all isolates, the isolate of the species F.
graminearum manifested the highest pathogenicity on the variety Reform with
average score of 4.43 and on variety Prima with 4.17.
