In order to establish a rapid identification technique of pear hardiness, combined with years of pearhardiness assessment, nine pear varieties（types） with different levels of hardiness were used as test materials, andthe correlation between lenticels and cold hardiness were studied. The results showed that the percentage of lenticelarea of 3 internodes which were of uniform thickness was significantly negative correlated with pear cold hardiness.As a result, the value could be used as an important indicator of cold hardiness of pear varieties（types）. Combinedwith field investigation and classification of pear hardiness, the percentage of lenticel area was taken as threshold.The pear cultivar（type） belongs to hardiest if the value is less than 1.5%; it belongs to hardier if the value is be-tween 1.5%~2.5%; it belongs to hardy type if the value is between 2.5%~3.5%; and it belongs to less hardy type ifthe value is more than 3.5%.
