Moreover,Guitang 46 has strong lodging resistance and good defoliation ability,which is suitable for both mechanical management and harvesting,and manual operations. Therefore,Guitang 46 is a new variety with high promotion potential. In June 2015,Guitang 46 was approved by Guangxi Crop Variety Approval Committee[GSZ2015001]. At present,Guitang 46 has been cultivated within a certain area.展开更多
