| Abstract: | Stylosanthes guianensis cv.Reyan No.7was selected from the collection of CIAT136introduced from CIAT in1982.The variety comparison trial from1985to1986,the regional trial from1987to1989and the pro duction trial from1991to2001showed that this variety produced high dry matter yield and had superior quality with anthracnose resistance,cold tolerance and late maturity.The S.guianensis cv.Reyan No.7produced14879.3kg/hm 2 of annual average dry matter yield and424.0kg/hm 2 ,84.0%and116.4%higher than those of S.guianensis cv.Graham(control)respectively.But there were no significant differences when compared to S.guianenesis cv.Reyan No.2.The crude protein content and the crude fat content of the S.guianersis cv.No.7were16.86%and2.65%respectively.Its growth period was239days.This new variety is suitable for green forage and hay meal production.And it adapts to grow in tropical and subtropical regions of China. |
