Abstract
The necrosis str. of groundnut mottle virus caused a variety of reactions in groundnuts and a disease index was developed to evaluate the reactions. Of 63 introductions 11 developed only a mild mottle with little or no stunting. Yield studies on 2 of the 11 introductions using a mild GMV str. (M2), predominant in the USA, showed a 31% seed loss in a susceptible cv. (Starr) but none in the introductions PI 261945 and PI 261946. The introductions were tolerant since there was no yield loss; furthermore 2-4 times more infectious virus was produced in them than in the 2 susceptible cvs. tested.ADDITIONAL ABSTRACT:In a glasshouse study to determine the effects of inoculation of groundnut cv. Starr and 2 introductions with (a) mild or (b) necrosis strains of peanut mottle virus, (a) caused a 31% loss in seed yield of the susceptible cv. Starr but no loss in yield of the 2 introductions. Seed yield of Starr was reduced by 68% following inoculation with (b) while the yield of 1 introduction was reduced by 48% and the other was unaffected.ADDITIONAL ABSTRACT:Of 63 introductions and eight cultivars inoculated with a strain of the virus generally causing necrosis, PMV-N, eleven introductions exhibited only mild mottling and little or no stunting. When two of them and susceptible Starr were inoculated with PMV-N, the effect on yield components was variable. However when inoculated with a mild strain of the virus, PMV-M2, the yield of the two introductions was not affected although they contained a higher concentration of the virus than Starr.
