Screening of soybean genotypes against soybean mosaic virus under natural and glass house conditions

Abstract

In view to check the infectivity of soybean mosaic virus on soybean plants under natural and glass house conditions 36 genotypes were screened. Field screening of soybean genotypes revealed that out of thirty six genotypes two were resistance (PS-1589 and PS-1587), while seven were moderately resistant (RVS-2009-09, AMS-MB-5-19, SL-1104, MASC-1520, RSC-10-70, SL-1113 and JS-9305) to SMV under field conditions. Glasshouse screening showed that out of nine promising genotypes which showed resistance/escape under field conditions, three showed resistant reaction (PS-1589, PS1587 and SL-1104), one genotype (SL-1113) showed moderately resistant reaction, three genotypes (RVS-2009- 09, RSC-10-70 and JS-9305) were categorized as susceptible while two genotypes (AMS-MB-5-19 and MASC-1520) showed moderately susceptible reaction.
