Screening of Advanced Breeding Lines (ABLs) of green gram [Vigna radiata (L.) Wilczek] in F6 generation for reaction to Mungbean Yellow Mosaic Virus (MYMV) disease under field condition

Abstract

Green gram is a store of nutrients and is a hardy pulse crop. It provides huge amount of phytochemicals and antioxidants but production is affected by many biological stress factors and among them MYMV stands first. Keeping this point in view, in the present investigation, 110 ABLs derived from fourteen families of green gram were evaluated for reaction to MYMV during summer-2019 at MARS, University of Agricultural Sciences, Dharwad, Karnataka. Amongst the breeding lines evaluated, 2BRD-2, 3BRD-18, 3BRD-9, 4BRD-1, 6BRD-9, 7BRD-7, 7BRD-12, 8BRD-20, E-19, PM-5 recorded resistant reaction and 5BRD-14 and 7BRD-13 recorded moderate resistance to MYMV with less than 10 per cent PDI value. Among 11 checks, TM-96-2 and SML-1815 showed resistance reaction; LGG-460 and RGM-1028 showed highly resistance reaction; MH-421 and IPM-409-4 showed moderately resistance reaction to MYMV with less than 20 per cent PDI value. These ABLs could be further used in resistant breeding programmes.
