Fungi Recorded on Exotic Rice Germplasm

Abstract

A large number of germplasm samples of rice are being exchanged throughout
the world for utilization in crop improvement programmes and such exchange has
an inherent risk of introducing exotic pests and pathogens as well as virulent races/
strains of the eXisting ones. Seed-borne pathogens of major importance in rice
seed are Pyricularia oryzae, Drechslera oryzae, Alternaria padwickii, Fusarium
monilforme, Fusarium graminearum, Tilletia barclayana, Cercospora oryzae, Balansia
oryzae, Rhizoctonia solani and Ustilagenoidea l'irens (Richardson, 1978).
