Abstract: A selective experiment on 13 Juglans mandshurica provenances was conducted in Linkou and Xinglong of Heilongjiang province by investigating the growth of one-year-old seedlings. The results showed significant differences in height and basal diameter growth of the provenances in the two test-sites. The excellent provenances adapted to Linkou area was Suiyang, Helong, Maoershan and Huinan. The excellent provenances were Fusong, Helong, Xinglong and Suiyang in Xinglong area. There was a significant correlation between the seed diameter and basal diameter growth of J.mandshurica in Linkou area. It could be regarded as the index of reflecting the basal diameter growth. The relationship between the growths of seed and seeding could be best described by the linear model. The correlations between the one-year-old seedlings growth of J.mandshurica and the main environmental factors of 13 provenances as well as two test-sites were analyzed. The results showed the height of one-year-old seedlings has a significantly negative correlation with the latitude and the annual temperature of locations. The provenances of J.mandshurica may be appropriately planting northwards.

Key words: Juglans mandshurica Maxim., provenance selection, variation of growth characters
