摘　　要：在61点(次)省级区域和生产试验中,川蔗23号的平均出苗率为66.67%;宿根发株数为181545株/hm2;平均分蘖率为115.32%;平均株高为257cm;平均茎径为2.94cm;平均有效茎为85035株/hm2;平均单株重为1.7752kg/株;平均单产为150855kg/hm2,比川蔗13号高28725kg/hm2,增产23.52%;平均田间锤度19.81%,比对照种高2.21%(绝对值);平均甘蔗蔗糖分为14.07%,比川蔗13号高1.72%(绝对值);甘蔗含糖量平均达21369.15kg/hm2,比川蔗13号高41.30%。在22点(次)全国甘蔗品种区域试验中,川糖89-103的平均出苗率是166.88%;分蘖率为114.14%,株高为269cm;茎径为2.81cm;有效茎是69798株/hm2,单株重是1.6290kg/株,新植宿根平均单产是11549,5kg/hm2,比全国统一对照种ROC10增产18.53%;平均甘蔗蔗糖分为14.49%,比ROC10高0.39%(绝对值);甘蔗含糖量为16209kg/hm2,比ROC10高18.40%。川蔗23号高抗黑穗病和花叶病,不感眼点病、黄斑病和褐条病等,对螟虫、蚜虫外的害虫有很强的抗性。川蔗23号商品性状优良,纤维含量低,出汁率高,蔗汁蔗糖分高,蔗茎表面光滑美观给人良好感觉。表明川蔗23号是一个农艺性状、产量性状和工艺性状及商品性状都很优秀的糖果兼用蔗品种。The result of Provincial Region Tests and Productive Trails in 61 points (times) is presented here. The emergence rate (average. the same below) of CZ23 was 66.67%; the numbers of sprouting was 181545 stalks/hm2, tillering rate was 115.32%; plant height was 257 cm, diameter was 2.94 cm, millable stalks was 85035 stalks/hm2, stalk weight was 1.7752 kg/stalk. Cane yield of CZ23 was 150855 kg/hm2, 28725 kg/hm2 (23.52%) higher than that of the check variety CZ13. The Brix was 19.81 ° Bx, 2.21 ° Bx (absolute value) higher than that of CZ13, sucrose content was 14.07%, 1.72% (absolute value) higher than that of CZ13; sugar yield was 21369.15 kg/hm2, 41.30% higher than that of CZ13. In the Nation District Experiments in 22 points (times), the emergence rate was 66.88%, the tillering rate was 114.14%, plant height was 269 cm, stalk diameter was 2.81 cm; millable stalks was 69798 stalk/hm2, stalk weight was 1.6290 kg/stalk. Cane yield for plants and ratoons was 115495 kg/hm2, 18.53% higher than that of ROC10, sucrose content was 14.49% in December to January, 0.39% (absolute value) higher than that of ROC10; sugar yield was 16209 kg/hm2, 18.40% (absolute value) higher than that of ROC 10. CZ23 is strongly resistant to srnut and mosaic, and immune to brown stripe, eyespot, Pokka etc. The variety was strongly resistant to many insects. CZ23 has many good commercial characters such as low fiber content, high percentage of juice and high sucrose content, good outward appearance etc. The results indicated that CZ23 is a fine variety with elite agronomic, yielding, technological and commercial characters both for grinding and for chewing.
