对瑞丽站育成含云南蛮耗细茎野生种血缘的第一个云蔗系列甘蔗新品种——云蔗99-155、云瑞99-113、云瑞99-131、云瑞99-178和云瑞99-601五个甘蔗新品系两新1宿品比试验,及部分品种(系)在云南省甘蔗品种区域试验的蔗茎产量、宿根能力、主要经济性状进行了统计分析,结果表明:(1)在站内品比试验中,5个品种(系)的产量、宿根能力均明显优于对照ROC10,其中,宿根能力最强的云瑞99-113较ROC10高27.42%,最弱的云瑞99- 601亦较ROC10高14.20%;5个新品种(系)均达到国家甘蔗品种审定标准。(2)在云南省区试中,云蔗99-155宿根能力较ROC10优势突出,达101.62%,蔗茎单产居15个参试品种之首;云瑞99-113宿根能力与ROC10相当,蔗茎单产比ROC10高7.92%,初步显示出云南蛮耗细茎野生种对甘蔗品种宿根性及适应性改良的效果。
The first sugarcane series new sugarcane varieties, Yunnan Cane 99-155, Yunrui 99-113, Yunrui 99-131, Yunrui 99-178 and Yunyun Rui 99-601 Two New Strains of Sugarcane New Strains, and Some Cultivars (Lines) of Sugarcane Varieties in Regional Experiments in Yunnan Province were analyzed statistically. The results showed that: ( 1) In the intra-plant ratio test, the yield and root-holding capacity of five cultivars (lines) were significantly better than that of the control ROC10. Among them, Yunrui 99-113 with the highest ability to host was 27.42% higher than ROC10 and the weakest Yunrui 99- 601 also 14.20% higher than the ROC10; 5 new varieties (lines) have reached the national approval standards for sugarcane varieties. (2) In Yunnan Province, the rooting ability of Yunji 99-155 was more prominent than that of ROC10 (101.62%), and the yield of cane stem was the highest among the 15 cultivars. Yunrui 99-113 had the same ability as ROC10 Stem yield was 7.92% higher than that of ROC10, initially showing the effect of Yunnan wildly consuming stem-stem wild species on the improvement of rootability and adaptability of sugarcane varieties.
