Selection of mild virus strains for controlling yellow mosaic disease of yard long bean

Selection of mild virus strains for controlling yellow mosaic disease of yard long bean

Mild strains of cowpea aphid-borne mosaic virus (CAMV) were selected by field selection mutagenesis. An attempt to select mild strain from natural field was failed. Mutagenesis by heat or cold treatment gave one and five mild virus strains, respectively. Nitrous acid treatment induced thirteen strai...

Zusammenfassung:Mild strains of cowpea aphid-borne mosaic virus (CAMV) were selected by field selection mutagenesis. An attempt to select mild strain from natural field was failed. Mutagenesis by heat or cold treatment gave one and five mild virus strains, respectively. Nitrous acid treatment induced thirteen strains of mild virus. Four of these nineteen mutants showed different level of cross protectivity when tested under greenhouse condition. The highest cross protection effectiveness was 75 % with strain 37C-30D obtained from heat treatment mutation.
