广东甘蔗新品种（系）比较试验

摘要

2013～2014年，在广东省内对6个甘蔗新品种(系)进行区域试验。结果表明，粤甘47号和粤甘43号较对照(ROC22和ROC16)增产、增糖幅度大，居参试品种前2名，它们均表现为早熟高糖，农艺性状优良。粤甘47号表现为萌芽好、分蘖力较强、植株较高、中大茎、有效茎数中等；粤甘43号表现为萌芽好、分蘖力强、全生长期生长稳健、植株中高、有效茎数多。%The results of the regional trial of 6 sugarcane varieties in Guangdong from 2013 to 2014 showed that both cane and sugar yield of Yuegan47 and Yuegan43 increased much more than those of the two checks (ROC22 and ROC16), ranking the first two of all the tested varieties (clones). They performed early maturity and good agronomic characteristics. Yuegan47 had good germination rate, good tillering rate and high plant and big diameter, and moderate millable cane, while Yuegan43 had good germination rate and tillering rate, and moderate plant height and many millable cane.
