For this the local landraces were collected from different districts of Assam viz., Jorhat, Biswanath, Sonitpur, Barpeta, Dibrugarh and Kokrajhar. Different symptoms like puckering of leaves, cupping of leaves, leaf rolling, purple colouration on leaves, calico pattern, mosaic symptoms, crinkling of leaves, etc. were observed. It was observed that the landrace from Barpeta had the highest disease incidence of 62.22 per cent and the lowest incidence of 10.00 per cent was observed in Badami aloo collected from Kokrajhar. PCR analysis of the symptomatic samples showed the presence of different viruses like PVY, PLRV, PVM, PVX, PVS and AMV. The potato tubers were also subjected to PCR analysis and only PLRV was detected with the highest incidence in Barpeta landrace (75.00 %). The growth and yield attributing characters of the landraces collected were also recorded. Plant height was observed to b |
