Abstract:

Among several factors responsible for low production and productivity, Urdbean leaf crinkle disease (ULCD) and yellow mosaic are considered to be the major threat for urdbean cultivation. The lack of resistance in urdbean against mixed infection of symptoms like crinkling, mosaic and bud deformation is major concern in urdbean productivity. In present study, the symptom based screening in urdbean accessions against leaf crinkle; bud deformation and yellow mosaic under natural conditions were done. The results revealed that all the three symptoms viz., crinkling, mosaic and bud deformation were observed from various accessions. The nature of the symptoms observed varied from severe to mild. All the accessions showed severe (50 -100 % leaf area) or moderate (20-50% leaf area) crinkling exceptKU-321, KU-1408, KU-1375 and KU-1373 which showed mild type of crinkling. The accessions KU-321, KU-1408 and KU-1375 showed only mild symptoms of crinkling, but no mosaic or bud deformation was observed, hence these can be used for cultivation after proper evaluation for yield parameters.
