Cold stress is one of most important abiotic stress in cold region of the world. The yield of autumn planting is higher than spring planting due to benefit of winter rainfall and higher water-use efficiency. Chickpea is grown on 700,000 hectare in Iran and ranks fourth in the world after India, Pakistan and Turkey. The objective of the present study was to evaluate chickpea promising lines for reaction to cold in growth chamber. The experimental material comprised 16 chickpea varieties in RCBD in two replications. Experiment was conducted in the pots in green house. After three weeks of germinate in pots in green house, the pots were transferred to growth chamber, where these hardened at 4 o C for 24 hours. The seedling grew for 14 hours in the dark and 10 hours in the light condition. After initial hardening the pots were kept at 0, -3,-6, -9, -12, -15 and -18 o C for one hour under each temperture in the growth chamber. Subsequently the pots were transferred for 12 hours to 4 o C. The results of present study showed that FLIP 93-255, FLIP 93-239, ILC8262, FLIP 84-42, FLIP 93-93, ILC482, Hasham, jam and Bivanij can tolerance -12 o C. Two lines such as Sel 93 th 24469 and FLIP 90-96 were tolerance to -15 o C. Sel 95 th 1716 and Sel 96 th 11439 were resistance to -18 o C and FLIP 97-239 was tolerance -18 o C. .
