SCREENING OF MUNGBEAN GERMPLASM FOR RESISTANCE TO MUNGBEAN YELLOW MOSAIC VIRUS (Pages : 11 - 15)

The experiment was carried out at the Regional Agricultural Research Station, Bangladesh Agriculture Research Institute, Rahmatpur, Barisal to screen mungbean germplasms against Mungbean Yellow Mosaic Virus (MYMV) during the period of January-May, 2012 late rabi season under natural epiphytotic condition. The experimentation comprised of 102 mungbean germplasms including resistant and susceptible check were used in this experiment. At flowering stage, out of 102 germplasm/varieties 5, 13, 18, 21, 13, 16, 12, 4 and 0 germplasm/varieties and at maturity stage 0, 18, 22, 26, 13, 9, 8, 6 and 0 germplasm/varieties were graded as no Infection (I0), 1-5% plants tissue infection (I), highly Resistant (HR), resistant (R), moderately resistant (MR), tolerant (T), moderately tolerant (MT), susceptible (S) and highly susceptible (HS) reaction, respectively. Among the less MYMV infected 18 mungbean lines, ACC-12840014 gives highest yield (2888 kg/ha) followed by VC-1007A (2844 kg/ha) and VO-1319 (B-G) (2788 kg/ha). The two lines ACC-12840014 and VO-1319 (B-G) completed by short duration of 66 and 64 days compare to check of 67.50 and 64.50 days. So, the lines ACC-12840014, VC-1007A and VO-1319 (B-G) were recommended as MYMV tolerant/resistant genetic material. Download
