摘要：

摘 要：为了更好地了解闽糖92-505的特性，为闽糖92-505大面积示范推广提供技术指导，对闽糖92-505从品种比较试验、福建省预备区域试验到国家区域试验的结果进行分析研究。结果表明：闽糖92-505萌芽率为74.66%，比对照种闽糖70-611高2.07%。分蘖率为109.06%，比闽糖70-611高33.51%。株高为296cm，比闽糖70-611低12cm。茎粗2.560cm，比闽糖70-611低0.013cm。有效茎数为84055条/ hm2，比闽糖70-611多18339条/ hm2，平均蔗茎产量118.424t/ hm2，11-2月份平均蔗糖份15.05%，平均含糖量17.887t/ hm2，比闽糖70-611增产24.30%、蔗糖份提高0.87个百分点，增糖32.20%。闽糖92-505早熟，高产稳产，适应性较广，中抗花叶病、抗黑穗病，抗旱能力中等。遗传组成分析结果表明，闽糖92-505共含有13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 Mingtang92-505，we studied on character of Mingtang 92-505 during the contrasting test to prepare regional trial and regional trial of new sugarcane variety in Fujian province and national， The investigative results were as follows: The germination was 74.66%, increase by 2.07% in comparison with the variety of Mingtang70-611. The tilling rate was 109.06%, plant height was 296cm, stalk diameter was 2.560cm, millable stalks was 84055stalk/hm2,mean cane yield was 118.424 t/hm2, sucrose content was 15.05 during the period of Nov. to Feb, sugar yield was 17.887t/hm2, increased by 33.51%, decreased by 12cm, 0.013cm, increased by 18339 stalk/hm2, 24.30%, 0.87% and 32.20% in comparison with Mingtang 70-611, respectively. Mingtang 92-505 had characters of early maturity ,high and stable in cane yield, wide adaptability, middle resistance to mosaic and drought、resistance to smut. The analysis of hereditary compose in Mingtang92-505 showed that it was abundant in hereditary , which content 13 different basic germplasm.
