Abstract

Pathogenic fungi detected in indigenous germplasm during 1999-2001.

Abstract

Seed health testing of 35 072 seed samples from different crops and their wild relatives showed a number of associated pathogenic fungi, i.e. Neovossia horrida [Tilletia barclayana], Ustilaginoidea virens, Alternaria padwickii, Ascochyta phaseolorum, Botryodiplodia theobromae, Colletotrichum dematium, Colletotrichum graminicola, Drechslera oryzae [Cochliobolus miyabeanus], Drechslera sorghicola [Bipolaris sorghicola], Drechslera sorokiniana [Cochliobolus sativus], Fusarium equiseti, Fusarium moniliforme, Fusarium semitectum [Fusarium pallidoroseum], Fusarium solani, Gloeocercospora sorghi, Macrophomina phaseolina, Rhizoctonia solani (=Thanatephorus cucumeris) and Sphacelotheca sorghi. A perusal of literature indicated the Botryodiplodia theobromae infecting Nelumbo nucifera in Andhra Pradesh, India, Colletotrichum gloeosporioides [Glomerella cingulata] on Trichosanthes palmata [Trichosanthes bracteata] in Madhya Pradesh, Fusarium equiseti on Cucumis spp. in Madhya Pradesh, Gloeocercospora sorghi on Sorghum vulgare [Sorghum bicolor] in Tamil Nadu, Rhizoctonia solani on Vigna mungo in Tamil Nadu and on Vigna aconitifolia in Rajasthan, are thought to be the new hosts for the said pathogens from the mentioned Indian states.
