摘要： 为了更好地了解闽糖86-2121的特性，为闽糖86-2121大面积示范推广提供技术指导，对闽糖86-2121从品种比较试验、福建省预备区域试验到福建省区域试验的结果进行分析研究，结果表明：闽糖86-2121萌芽率为61.32%，比对照种闽糖70-611低5.90%。分蘖率为134.97%，比闽糖70-611高44.21%。株高为305cm，比闽糖70-611高6cm。茎粗2.621cm，比闽糖70-611粗0.078cm。有效茎数为73374条/ hm2，比闽糖70-611多11479条/ hm2，平均蔗茎产量117.581t/ hm2，11-2月份平均蔗糖份14.40%，平均含糖量16.938t/ hm2，比福建目前主栽品种闽糖70-611增产28.06%、蔗糖份提高0.19个百分点，增糖29.85%。中晚熟，高产稳产，适应性广。高抗嵌纹病、黑穗病、赤腐病、梢腐病和锈病，抗旱能力中等。遗传组成分析结果表明，闽糖86-2121共含有14个不同基础种质，遗传组成丰富。

Abstract: For providing technical director for large area demonstration and popularization of Mingtang86-2121，we studied on character of Mingtang 86-2121 during the contrasting test to prepare regional trial and regional trial of new sugarcane variety in Fujian province ， The investigative results were as follows: The germination was 61.32%, decrease by 5.90% in comparison with the variety of Mingtang70-611. The tilling rate was 134.97%, plant height was 305cm, stalk diameter was 2.621cm, millable stalks was 73374 stalk/hm2,mean cane yield was 117.581 t/hm2, sucrose content was 14.40 during the period of Nov. to Feb, sugar yield was 117.58t/hm2, increased by 44.21%, 6cm, 0.078cm, 11479 stalk/hm2, 28.06%, 0.19% and 29.85% in comparison with Mingtang 70-611, respectively. Mingtang 86-2121 had characters of middle to late maturity ,high and stable in cane yield, wide adaptability, strongly resistance to mosaic、smut、red rot、pokkah boeng、rust and drought. The analysis of hereditary compose in Mingtang86-2121 showed that it was abundant in hereditary, which content 14 different basic germplasm.
