中文摘要:为筛选抗梢腐病的甘蔗品种,于2016—2019年采用田间自然发病率调查方法对我国近年选育的60个新品种及云南省临沧市、普洱市、玉溪市和广西壮族自治区宜州区甘蔗梢腐病高发蔗区的31个主栽品种进行自然抗性评价。结果表明:在60个甘蔗新品种中,35个表现为高抗、抗病和中抗,所占比例为58.3%,其中高抗品种5个、抗病品种15个、中抗品种15个,所占比例分别为8.3%、25.0%、25.0%;在31个甘蔗主栽品种中,15个表现为高抗、抗病、中抗,所占比例为48.4%。目前大面积种植的新台糖25号、粤糖93-159、盈育91-59、柳城03-1137、云蔗03-258、川糖79-15、新台糖1号、桂糖11号、桂糖42号9个主栽品种对甘蔗梢腐病高度感病,而近年选育的粤甘49号、福农11-2907、闽糖11-610、闽糖12-1404、桂糖11-1076五个新品种对甘蔗梢腐病高抗,粤甘46号、粤甘47号、福农09-2201、福农09-6201、福农09-7111、福农10-14405、闽糖06-1405、桂糖40号、桂糖44号、桂糖06-1492、桂糖06-2081、桂糖08-1180、桂糖08-1589、云蔗11-1074和德蔗07-36共15个新品种对甘蔗梢腐病表现抗病。

Abstract:To screen sugarcane varieties resistant to pokkah boeng, from 2016 to 2019, the field resistance of 60 newly-bred and 31 main cultivated varieties was evaluated against pokkah boeng in Lincang, Puer and Yuxi cities of Yunnan Province, and in Yizhou District of Guangxi Zhuang Autonomous Region, where the incidence of pokkah boeng was particularly high. Among the 31 main cultivated varieties, 15 were highly resistant, resistant and moderately resistant against pokkah boeng, accounting for 48.4%. Nine main cultivated varieties that are currently grown in large areas, including ROC25, Yuetang93-159, Yingyu91-59, Liucheng03-1137, Yunzhe03-258, Chuantang79-15, ROC1, Guitang11, and Guitang42, were highly susceptible to pokkah boeng. The result showed that 35 of 60 new sugarcane varieties (58.3%) were highly resistant, resistant and moderately resistant. Of these, five varieties were highly resistant, 15 resistant and 15 moderately resistant, accounting for 8.3%, 25.0%, 25.0%, respectively. Five highly resistant newly-bred varieties included, Yuegan49, Funong11-2907, Mintang11-610, Mintang12-1404, Guitang11-1076. The 15 resistant newly-bred varieties included Yuegan46, Yuegan47, Funong09-2201, Funong09-6201, Funong09-7111, Funong10-14405, Mintang06-1405, Guitang40, Guitang44, Guitang06-1492, Guitang06-2081, Guitang08-1180, Guitang08-1589, Yunzhe11-1074, and Dezhe07-36.
