Field screening of greengram (Vigna radiata L.) genotypes for resistance against major viral diseases
Author(s): A Vijaya Bhaskar
Abstract: Green gram genotypes were evaluated to identify the sources of resistance to Mung bean Yellow Mosaic Virus and Urdbean Leaf curl Crinckle Virus diseases. Screening was done under natural field conditions at Regional Agricultural Research Station, Warangal, Telangana State, India. The experimental material consisted fifty seven All India Coordinated Research Project and state ninteen Green gram entries with one check during Kharif-2017 and nineteen AICRP and twelve state green gram entries with a check during Rabi-2017, which were screened against the major viral diseases at RARS, Warangal. Out of one hundred eleven Green gram entries, one entry viz., WGG-42 was found immune to mung bean yellow mosaic virus disease. Out of seventy eight green gram entries were screened against urdbean leaf crinckle virus disease during Kharif 2017, the disease severity index in seventy eight AICRP green gram germplasms lines range was from 1% to 5%. Based on the disease reaction of both replications during Kharif-2017, thirty entries viz., BM 4, AKM 8802, AKM 12-28, ML- 2479, ML-818, SKNM 1504, SKNM 1502, VGG 16-036, LGG 607, LGG 460, LBG 450, Pant M4, PM 14-11, COGG 13-39, KM 2355, KM 2241, K 851, Pusa 0672, NDMK 16-324, JLM-30246, JAUM0936, MH1142, IPM 02-3, IPM 312-19, Kopergoan, MGG-387, MGG-295, MGG-359, MGG-360 and MGG-434 were found resistant to urdbean leaf curl virus disease.
