Abstract:
Maturity group(MG)is a widelyused system for soybean varieties classification in the world.In the current study,we identified the MG categories for local popular planted and recently released soybean varieties of Sichuan with 27 MG standard varieties from the USA.In 2011,there were no obvious borders between maturity groups of the USA standard varieties,resulting in most of tested varieties had no corresponding maturity groups.In 2012,the USA standard varieties had obvious border and every variety could be classified into a certain maturity group.Results showed the early maturing varieties which were suitable for large area planting in Sichuan mainly belonged to maturity group Ⅱ and Ⅲ,the latematuring ones mainly belonged to maturity group
