Summary on regional trials of improved spring soybean varieties in Guangxi from 1982-2008

【Objective】The present paper summarizes the results of regional trials conducted for improved spring soybean varieties introduced and bred in Guangxi from 1982-2008, and also the efforts have been made to popularize the cultivation of fine soybean varieties. 【Method】The results of regional trials have been summarized year wise from the first to ninth cycle. The requirements of regional trials included test personnel, working unit, plot design, threshing and yield estimation, and also the circumstances of experimental conditions from the 1982 to 2008 have been introduced. 【Result】 Sixty spring soybean varieties have been identified and tested, 35 fine varieties were selected for their better characters, of which, 14 varieties, viz., Guizao 1（8901）, Guizao 2（199）, Guichun 1（Gui 313）, Guichun 2 （Gui 292）, Guichun 3 （Gui 4-228）, etc., were certified or registered by Guangxi Committee for Crop Variety Registration. 【Conclusion】Some fine varieties which passed the regional trials have been extended for cultivation in Guangxi, which led to the restructuring of crop planting structure and process of soybean breeding in Guangxi.
