湘两优糯粱1号引种试验

Preliminary Report on Introduction Trial of Xiangliangyounuo Sorghum No.1

湘两优糯粱１号是湖南省农科院土肥所用二系法育成的杂交糯高粱．１９９６年引进浙江省试种，我们证实了它的高产潜力，高产攻关田产量达７８３７．５ｋｇ／ｈｍ２，地区试验中产量为５５５６．０ｋｇ／ｈｍ２，比当地品种增５０．０２％．该杂交种有良好的食味和籽粒外形，抗病抗倒．本文介绍了该杂交种的特征特性，并提出了相应的高产栽培技术．

Xiangliangyounuo Sorghum No.1 was developed through the two line method by the Soil and Fertilizer Research Institute,Hunan Academy of Agricultural Sciences. This hybrid combination was introduced into Zhejiang Province in 1996. We confirmed its high yield potential (7837.5 kg/hm 2 in the high yielding trials,and 5556.0 kg/hm 2 in the local trials,respectively).As compared to a local cultivar,it yielded 50.02% higher.This hybrid combination has fine grains with good eating quality.It is resistant to diseases and lodging. Here we presented its agronomic characters and proposed appropriate cultivation techniques for obtaining high yields.
