Abstract:

12 MG standard varieties of MG0~MGⅢ from north USA sown in Sanjiang plateau of Heilongjiang were used as reference to identify the MG categories for local popular varieties in Heilongjiang in 2012 and 2013. The results showed that the maturity group’s growth period of the north USA standard varieties presented constant increase trend, and the borders were obvious that can be used for maturity group classification. There were significant differences in different growth period between group varieties and standard varieties. Results from 2 years showed that Huajiang 2, Heihe 38, Heihe 43 and Heihe 45 belonged to MG0 group; Hefeng 51, Hefeng 50, Hefeng 55, Suinong 26, Suinong 28 and Heinong 44 belonged to MGⅠgroup; the varieties of Kenfeng 16 and Heinong 51 belong to MGⅡ group.
