12点(次)省区试和生产试验结果表明,川蔗26号的平均出苗率为41.94%,比对照(华南54-11)高2.27%;平均分蘖率为66.13%,比对照高4.46%;平均株高为256 cm,比对照高20 cm;平均茎径为3.17 cm,比对照大0.20 cm;平均有效茎为61545株/hm2,比对照多7605株/hm2;平均单株重达2.0181kg/株,比对照重0.3783 kg/株;平均甘蔗单产达125400 kg/hm2,比对照高35970 kg/hm2,增产40.22%;平均蔗汁抽出率为79.29%,比对照高1.04%;平均蔗汁蔗糖分为13.15%,比对照高0.53%,故其清爽甘甜而令消费者喜爱;平均甘蔗纤维分为6.90%,比对照低0.18%,故其蔗茎松软泡脆;还原糖与对照种相当;其茎色紫红,蔗茎粗大,故其卖相好而市场竞争力很强;平均田间锤度为16.87%,比对照高0.58%;甘蔗蔗糖分平均为12.20%,比对照高0.27%:甘蔗含糖量平均达14910 kg/hm2,比对照多4875 kg/hm2,增产48.58%;抗倒性极强,抗旱性较强,高抗甘蔗黑穗病,还抗甘蔗褐条病及甘蔗花叶病,轻感甘蔗梢腐病;较抗甘蔗二点螟等甘蔗害虫;抗寒性较差;宿根性较差。所以,川蔗26号是一个农艺、产量、商品和工艺等多数性状优良的高产、优质、具有多种抗性、品质与Badila接近的优良果蔗品种。
At 12 o’clock, the provincial trial and production test showed that the average germination rate of Sichuan sugarcane was 41.94%, which was 2.27% higher than that of the control (South China 54-11), the average tillering rate was 66.13%, which was 4.46% ; The average plant height was 256 cm, 20 cm higher than the control; the average stem diameter was 3.17 cm, 0.20 cm larger than the control; the average effective stem was 61545 plants / hm2, 7605 plants / hm2 more than the control; kg / plant, 0.3783 kg / plant heavier than the control; the average yield of sugarcane reached 125400 kg / hm2, 35970 kg / hm2 higher than that of the control, yielding 40.22%; the average extraction rate of sugarcane juice was 79.29%, 1.04% higher than that of the control; Juice sucrose is divided into 13.15%, 0.53% higher than the control, so the sweet and refreshing consumers love; the average sugar cane fiber is divided into 6.90%, 0.18% lower than the control, so the cane stems soft and crisp; reducing sugar and the control The average stem weight is 16.87%, which is 0.58% higher than that of the control; the average sucrose content of sugarcane is 12.20%, which is 0.27% higher than that of the control; The average sugar content of sugarcane reached 14910 kg / hm2, 4875 kg / hm2 more than that of the control, with an increase of 48.58%. The results showed that the sugar content of sugarcane was high, its resistance to sugarcane smut was high, Leaf disease, Sensing cane shoot rot; two-point more anti Sugarcane Sugarcane borer pests; poor cold; perennial poor. Therefore, Sichuan Cane 26 is a good variety with excellent yield, good quality and variety of traits, such as agronomic, yield, commodity and technology. It has many kinds of resistance and the quality is close to Badila.
