能糖兼用甘蔗新品种的评价与利用

Evaluation and utilization of new varieties of sugarcane for energy and sugar

对近年选育的12个甘蔗新品系进行了产量、品质及其主要工农艺性状的研究.结果表明:FN99-20169、FN02-3924和FN02-6404表现早熟、高产、高糖,且工农艺综合性状优良,可望选育成为能糖兼用新品种;FN02-6427也具有早熟、高产、高糖和茎粗等优点,但开花较早,有一定的推广价值,宜较早收获;FN01-0241工农艺性状和产量表现较差,生产利用前景有限,但具有早熟特高糖的特性,可试作高糖亲本应用.早期田间锤度研究表明,FN02-3924属特早熟高糖品系,作能源甘蔗可提早2个多月开榨,具有广阔的应用前景.

Yield, quMity and other characteristics were compared for 12 sugarcane clones at variety yield test stage. The results in- dicated that FN99-20169, FN02-3924 and FN02-6404 showed early maturity with higher sucrose content, higher yield, and better synthetic characters. FN02-6427, showing its advantages in early maturity, high yield, high sucrose content and great stalk diame- ter, but with early flowering, had some potential prospect as early,harvest clone. The agronomic characteristics and yield of FN01-0241 showed less potential comparatively, but it can be trailed as high sucrose content parent. Early brix research indicated that FN02-3924 maturated particularly early, it could be harvested earlier for more than two months.
