Ten isolates of Fusarium spp. (F. proliferatum)
(4 isolates), F. verticillioides (5 isolates), and
F. pallidoroseum (1 isolates) were collected from
different parts of Rajasthan from rotted maize
stalks and identified by ITCC, IARI (New Delhi,
India). The maximum colony diameter (90mm),
sporulation (3.4x105 X 3.8x105), size of macroconidia
(40.24 X 6.60) and microconidia (10.33 X
1.50) and septation (5-7) were observed in isolate
Fv-01 (F. verticillioides) whereas minimum colony
diameter (54.70mm), sporulation (0.8 x105 X 1.6
x105), size of macroconidia (17.57 X 1.80) and
microconidia (9.09 X 1.48) was observed in isolate
Fv-09 (F. proliferatum) . On the basis of cultural
and morphological characters of all the ten
isolates showed variability, but based on RAPDPCR
analysis, these isolates can be categorized
into two major clusters I and II at 0.44% similarity
coefficient. RAPD-PCR analysis suggested that
variability was observed between species of
Fusarium recovered from maize and the technique
could be use to complement morphological
characterization and to determine genetic
relationships between the species.
