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.
Highlights
The pulses are rich source of protein; due to this they are called “poor man’s meat”
The screening of urdbean (Vigna mungo) germplasm was done against urdbean leaf crinkle virus (ULCV) under field conditions
Among environmental factors temperature played an important role in disease development
Summary
The pulses are rich source of protein; due to this they are called “poor man’s meat”. Conventional development of this pulse crop is basically kept in the nations of south Asia and contiguous area including Pakistan, Sri Lanka, Bangladesh, Afghanistan and India. In combination with grain Urdbean seed satisfies the prerequisite of protein (24%) in diets, less amount of sulphur containing amino acids, lycine and phosphoric acid [13]. It is mostly utilized as "dal" and in preparation of some extraordinary dishes like the sprouted urdbean which is extremely prominent dish in Japan and is exceedingly regarded for digestibility [16].
