ABSTRACT

Urdbean or mashbean is one of the most valuable leguminous crops all over the world. It is under the attack of numerous diseases caused by different pathogens. Among these urdbean leaf crinkle virus (ULCV) is one of the most devastating and widely distributed. It is naturally transmitted through whitefly (Bemisia tabaci). To combat this problem, eight urdbean genotypes (Arooj, 6065-3, 6036-21, 4em-716, ES-I, M-95, ARRIM-08 and ARRIM-16) were screened out against urdbean leaf crinkle virus and correlated with epidemiological factors (temperature, relative humidity). The overall results revealed that, among all these lines, one genotype (M-95) was susceptible, three genotypes (6065-3, 4em-716, ES-I) were moderately susceptible, three genotypes (6036-21, ARRIM-08, ARRIM-16) moderately resistant and only one genotype showed resistance response to urdbean crinkle virus. A positive correlation was observed between disease prevalence and all environmental factors.
