According to the situation of water resources shortage and drought disaster in Heilongjiang Province, a test was carried up to screening and identification the drought resistance rice varieties of the second and the third accumulated temperature zone in Heilongjiang Province. The results showed that, the drought resistance of Suigeng 3, Suigeng 8, Suigeng18 and Longgeng 31 were better; the first main factor affecting the drought resistance of rice was root activity of seedlings stage, and then followed by root activity of active tillering stage, effective panicle number, grain number per spike, filling rate of superior grain and days from sowing to earing.
Key words: rice; drought resistant; correlation; principal component analysis
