A field experiment was undertaken to evaluate the varietal tolerance and accumulation of arsenic by different potato cultivars at village Nonaghata in Nadia district of West Bengal during winter season of 2008-09 and 2009-10. Arsenic content in the irrigation water was 0.094 to 0.108 mg/l. Arsenic accumulation of different plant parts was in the following sequence: root > stem > leaf > tuber, irrespective of all cultivars. After harvesting, the least arsenic loading was observed in cultivar Kufri Jyoti (0.05 mg/kg) which also showed the highest productivity (32.32 t/ha). Cultivar Kufri Chandramukhi and locally grown variety Lal alu accumulated a lesser amount of arsenic and had also a higher yield compared with the other entries.
