10个糖能兼用甘蔗品种（系）的性状表现

摘要

To meet the demand for sugarcane varieties in the sugarcane industry and breed reserve for future sugarcane to produce fuel ethanol,the variety comparison test of planting and ratoon of 10 sugarcane varieties and Guitang11(CK)was conducted in order to understand characteristics of performance of the sugarcane varieties for sugar and energy in 2011-2012 in Guizhou.The results indicated that Guitang96/211,Qianzhe 06/212 and Dezhe 03/83 showed better comprehensive characters.Sugarcane stalk yield was 24.49%,29.89% and 25.45% higher than CK respectively.Sucrose content was 34.92%,38.92% and 37.08% higher than CK.The femmentable sugar content was 33.46%,38.63% and 39.31% higher than CK separately.Yield of sugarcane stem achieved more than 120 t/hm2 technical requirements of varieties of sugarcane for energy either.Both can popularized for the fine varieties of sugar sugarcane can also be developed for sugarcane of energy.Sucrose content of Ganzhe18, Qianzhe 06/89,Yunzhe 03/45 and Qianzhe 06/156 was 27.69%,25.15%,19.15% and 11.69% higher than CK,which can be popularized and utilized as the fine sugar sugarcane varieties.%为满足贵州蔗糖业对甘蔗良种的需求，为今后甘蔗生产燃料乙醇进行品种储备，于2011-2012年以贵州主栽品种桂糖11号为对照，对鉴选出的10个甘蔗品种（系）进行新植和宿根品比试验，了解不同糖能兼用甘蔗品种（系）在贵州的性状表现。结果表明：桂糖96/211、黔蔗06/212和德蔗03/83综合表现优良，蔗茎产量分别超对照24．49％、29．89％和25．45％，蔗糖含量超对照34．92％、38．92％和37．08％，可发酵糖含量超对照33．46％、38．63％和39．31％，并且蔗茎产量达到能源甘蔗品种120 t/hm2以上的技术要求，在贵州既可作为优良的糖蔗品种（系）推广应用，也可作为能源蔗开发利用；赣蔗18号、黔蔗06/89、云蔗03/45和黔蔗06/156蔗糖含量分别超对照27．69％、25．15％、19．15％和11．69％，可作为优良糖蔗品种（系）推广应用。
