Screening of Groundnut Varieties and Germplasm against Collar rot, Stem rot and Dry Root rot Diseases

FOREST PATHOLOGY Root and Butt Rot Diseases

Diseases caused by root rots figure prominently amongst the most-studied pathologies of forest trees. Indeed, root and butt rots cause more economic damage to commercial forestry in the temperate world than any other known type of disease. While this notoriety underlines the negative impact of this type of disease on timber production, a much more dynamic and positive role can be assigned to ro...

Resistant to Fusarium Root Rot

Journal of Plant Registrations, Vol 2, No. 2, May 2008 137 Three F8–derived breeding lines, W6 26740 (RIL 846_34; GP-96, PI 652444), W6 26743 (RIL 846_40; GP-97, PI652445), and W6 26745 (RIL 847_36; GP-98, PI 652446), of green pea (Pisum sativum L.) were selected from a recombinant inbred line population developed by the USDA–ARS in 2000. These lines are unique in combining high levels of resis...

Biological control of collar rot disease with broad-spectrum antifungal bacteria associated with groundnut.

Bacteria associated with 6 habitats of groundnut were evaluated for their broad-spectrum antifungal activity and suppression of collar rot (Aspergillus niger) of groundnut. Three hundred and ninety-three strains were tested against 8 fungal pathogens of groundnut including 5 necrotrophic fungi, Aspergillus flavus, A. niger, Rhizoctonia bataticola, Rhizoctonia solani, and Sclerotium rolfsii, and...
