Mungbean Yellow Mosaic Virus (MYMV) is one of the most important diseases of Mungbean. It is transmitted through whitefly (Bemisia tabaci). The present investigation aimed to identify stable MYMV resistant lines through screening under natural condition. The experimental material consisted of 120 germplasm lines screened under field condition at two locations during kharif, 2013. Screening for MYMV resistance was done by planting infector rows along with the test entries. Results revealed that most of the genotypes studied were categorized as moderately susceptible to highly susceptible in both the locations. None of the test entries appeared to be immune. It was observed that the genotype shows differential response against MYMV at these locations. In spite of the variable response to MYMV, the genotypes EC 398897, TM-11-07, TM-11-34, PDM-139, IPM-02-03, IPM-02-14, Pusa-0672, Pusa-0871, CO-7 and MH-521 exhibited resistance in both the locations and these genotypes would be utilized as donors to develop MYMV resistant lines.

Abstract


Mungbean Yellow Mosaic Virus (MYMV) is one of the most important diseases of Mungbean. It is transmitted through whitefly (Bemisia tabaci). The present investigation aimed to identify stable MYMV resistant lines through screening under natural condition. The experimental material consisted of 120 germplasm lines screened under field condition at two locations during kharif, 2013. Screening for MYMV resistance was done by planting infector rows along with the test entries. Results revealed that most of the genotypes studied were categorized as moderately susceptible to highly susceptible in both the locations. None of the test entries appeared to be immune. It was observed that the genotype shows differential response against MYMV at these locations. In spite of the variable response to MYMV, the genotypes EC 398897, TM-11-07, TM-11-34, PDM-139, IPM-02-03, IPM-02-14, Pusa-0672, Pusa-0871, CO-7 and MH-521 exhibited resistance in both the locations and these genotypes would be utilized as donors to develop MYMV resistant lines.
