摘　　要：广西甘蔗研究所1996年从墨西哥引进桂引9号(原名Mex105)。经多年多点试验,该品种表现早熟、高产、高糖,宿根性好,抗病性强,在广西蔗区区域试验中,公顷产蔗量92.3t,比对照种新台糖16号增产12.2%,平均蔗糖分16.08%,比新台糖16号增1.23%,公顷含糖量为14.8t,比新台糖16号增糖21.4%,增产增糖效果显著。高产栽培上侧重于增加有效茎数和提高蔗株的高度。每公顷产蔗量90～120t的合理群体结构为:公顷有效茎为7.00～7.85万条,株高297～325cm,茎径2.53～2.71cm。The sugarcane Guiyin9 was introduced from Mexico in 1996, and the variety was early maturing, high sugar content, high yield, strong ratoon ability, high resistance to disease. The results of regional trial showed that its cane yield （92.3t/ha） was increased by 12.2%, sucrose content （16.08%） was increased by 1.23% and sugar yield （14.St/ha） was increased by 21.4% in comparison with the variety ROC10 （CK1）, respectively. High cultivation measures are mainly increasing the millable stalks per hectare and the stalk height. In high yielding cultivation （cane yield 90 to 120 t/ha）, it is the most rational with 70000-78500 stalks/ha in millable stalks, 297- 325 cm in stalk height, and 2.53-2.71 cm in stalk diameter.
