 en Screening Cowpea and Soybean Cultivars for Resistance to Anthracnose and Brown Blotch Diseases using Phytotoxin Metabolites
Amusa, N.A; Ikotu, T & Osikanlu, Y.O.K

Abstract

Toxin metabolites of Colletotrichum lindemuthianum check for this species in other resources and C. truncatum produced in culture induced necrotic lesions on cowpea and soybean leaves, stems and pods. Bioassay of the culture filtrates of the two pathogens using 14 cultivars each of cowpea and soybean indicated that host plants reacted differentially by producing different sizes of lesions. The 14 cultivars were grouped as susceptible, moderately resistant and resistant, and groupings were similar to those reported form field tests using C. lindemuthianum and C. truncatum on cowpea and soybean cultivars.
