川糖2008-7307是从组合湛蔗92-126×粤糖89-240经多年选育出的果蔗新品种。多年多点试验结果表明:该品种出苗较好,苗壮,分蘖中等,植株高大,茎粗;高抗黑穗病、花叶病,轻感梢腐病,抗倒性强,宿根性好,易脱叶;高产稳产,品质好,口感好。多年多点省区试和生产示范结果表明:川糖2008-7307的平均蔗茎产量达到128.06 t/hm~2,比对照品种华南54-11的101.38 t/hm~2增产26.31%,差异达极显著水平;11—12月平均蔗糖分达14.0%,比对照高1.9个百分点;总糖含量达15.8%,较对照高0.5个百分点;蔗汁抽出率达74.9%,较对照高0.6个百分点;纤维分8.0%,较对照高0.3个百分点;含糖量达17.93 t/hm~2,比对照增加5.66 t/hm~2,增糖达46.13%。该品种是一个农艺性状、工艺性状和商品性状均优于或与对照种相当的优良果蔗新品种,具有较好的推广应用前景。
Chuanxiong 2008-7307 is a new sugarcane variety bred from the combination of Zhanzhan 92-126 × Yueshun 89-240 for many years. The results of multi-year trial showed that this variety had better emergence, strong sprouting, medium tillering, tall plant, thick stalk; high resistance to smut, mosaic disease, light shoot rot, strong lodging resistance, Yi Xieye; high and stable yield, good quality, good taste. The demonstration results of multi-year provincial trial and production showed that the average cane yield of Sichuan sugar 2008-7307 reached 128.06 t / hm ~ 2, which increased by 26.31% compared with 101.38 t / hm ~ 2 of 54-11 in South China. And the average sugar content was 15.8%, 0.5% higher than the control; the extraction rate of sugarcane juice was 74.9%, 0.6 percentage points higher than that of the control ; Fiber 8.0%, 0.3% higher than the control; sugar content of 17.93 t / hm ~ 2, increased 5.66 t / hm ~ 2 compared with the control, increased sugar 46.13%. The variety is an agronomic trait, technological traits and commodity traits are superior to or comparable with the control of new varieties of good sugarcane, has good prospects for the promotion.
