云南甘蔗品种第12套区试勐海点评价

摘要

2 years planting and 1 year ratoon trial of 10 clones was conducted in Menghai. The result showed that SP81-3250, SP80-3280, Yunzhe06-160 and Yunrui05-292 obtained sugar yields 10% more than that of check varieties. Among them, SP80-3280 and Yunrui05-292 showed good performance and therefore were recommended for further propagation. SP81-3250 was susceptible to woolly aphids and thin-stemmed, Yunzhe06-160 was easy-lodging and thin-stemmed, Yunnong01-14 and C266-70 showed bad performance, therefore they should be eliminated from application. More trial should be done for the others.%10个参试品种在勐海点进行了2年新植1年宿根试验，结果表明：比2对照种增产增糖10%以上的甘蔗品种为SP81-3250、SP80-3280、云蔗06-160、云瑞05-292。其中SP80-3280和云瑞05-292综合性状表现较好，中大茎种，建议加速扩大繁殖；SP81-3250茎较细，易受蚜虫为害；云蔗06-160茎细，易倒伏；云农04-14、C266-70综合性状表现较差，建议给予淘汰；其余品种建议继续试验观察。
