Sugarcane ís one of the important industrial crop in Vietnam. However in its production there is lack of set of variety with high performance..So that we carry out this research on sugarcane breeding and got following records: Evaluation and identified 40 clones and varieties that used as parents in 20 single crosses and obtained more than 7000 hybrids. In the first step selection are identified 8 crosses with 174 clones with good morphological characters. Among of them there are 48 clone having Brix >20%.In the last clone selection step there are 13 promising clones.In these promising clones are identified five ones having yielding equal check variety’ yielding (ROC26).Special clone No.VN09-108 and VN09-145 yielded 118 ton/ha and 120 ton/ha respective. These yielding are higher than yielding of ROC26 (116 ton/ha). These clones are in-vitro propagated for trial experiment in different ecological area.
