In order to solve the problem of legume variety shortage in sub-tropical red soil region,Chamaecrista rotundifolia Greene.（CPI 86134） was firstly introduced from ATFGRC,Australia in 1996,and was registered and named C.rotundifolia cv.Minyin by China Forage Cultivar Registration Board in 2005.Variety comparison trial,regional trial and productive trial was carried out during 1997 to 1999,1998 to 2001,and 1999 to 2002,respectively.Results show that Minyin was an important annual or perennial tropical legume with hay yield of 9400 to 11000 kg・hm-2 and seed yield of 140 to 280 kg・hm-2 which were 130% and 77 % higher than those of cultivar Wynn.Crude protein content was 17% when harvested at full blooming stage.In summary,Minyin should be recommended for extensive planting,due to its good performance,on hilly red soils in tropical and sub-tropical region in China.[著者文摘]
