摘　　要：为探寻适宜百色市种植的甘蔗优良品种,不断提高百色市的甘蔗产量和品质,实现甘蔗品种的多样化,并能够对百色市的甘蔗品种结构进行不断地优化,根据2019~2021年参加百色市甘蔗新品种展示,调查和研究了这些甘蔗新品种的农艺状态、抗病虫害性、经济性状等综合表现情况,并对此进行了比对分析和综合评价。结果表明:根据甘蔗农艺性状分析,发株率、株高最高的是桂糖42号(CK),云蔗09-1601的分蘖率最高,茎径最粗的是粤甘47号,有效茎数最多的是桂糖58号;根据经济性状分析,蔗糖分最高的是桂糖42号(CK),桂糖55号含糖量最高;根据病虫害分析,枯心病的发生率最高发生在2020年的桂糖42号(CK),发生率为9.77%,黑穗病发生率最高的是桂糖42号(CK),最低的是桂糖58号,梢腐病的发生率最高的粤甘43号。综合上述结果,桂糖55号、桂糖58号的经济性状更有优势,属于高产品种,且病虫害率较低。In order to explore suitable sugarcane varieties in Baise city,the yield and quality of sugarcane in Baise city should be continuously improved to realize the diversification of sugarcane varieties,and optimize its structure.This paper studied the sugarcane varieties exhibited in Baise City from 2019 to 2021.The comprehensive performance of these new sugarcane varieties,such as agronomy,disease and pest resistance,economic comprehensive performance,and the comparison analysis are investigated and studied.The test results showed that,according to the sugarcane agronomic trait analysis,the highest strain rate and plant height is cinnamon no.42(CK);cloud cane 09-1601 had the highest tillering rate;Yuegan 47 had the largest stem diameter,and cinnamon sugar 58 had the largest effective stem number.According to the economic trait analysis,the highest sucrose score was cinnamon 42(CK);Cin.55 has the highest sugar content;According to the analysis of diseases and insect pests,the highest incidence of dry heart disease occurs in cinnamon no.42(CK)in 2020,with an incidence of 9.77%.The highest incidence of smut is cinnamon no.42(CK);the lowest is cinnamon sugar 58;the highest incidence of shoot rot is Yuegan 43.Based on the above results,the economic traits of cinnamon sugar 55 and cinnamon sugar 58 are more advantageous,belonging to high-yield varieties with low disease and insect pest rate.
