2006年叶菜型甘薯新品种国家区试广西试点的分析

Study of National Regional Experiment on Vine-vegetable Sweetpotato in Guangxi 2006

[目的]为了筛选高产优质、抗逆性强的叶菜型甘薯,为其在生产上的推广和应用奠定基础。[方法]通过2006年的国家叶菜型甘薯品种区试,测定福薯10号、福薯11号、广薯菜1号、广薯菜2号、阜菜薯1号、莆薯53和福薯7-6(CK)7个甘薯品种的茎叶产量,并进行品质鉴定。[结果]各参试品种茎叶产量均比对照增加,福薯10号产量最高,单产为29599.5 kg/hm2,比对照增产41.3%。其次是莆薯53和广薯菜2号,单产分别为26899.5和26850 kg/hm2,比对照增加28.4%和28.2%。品质鉴定除阜菜薯1号和广薯菜1号稍差外,其余品种都较优,适于在广西种植。综合排名前3名的是福薯10号、莆薯53和广薯菜2号。[结论]该研究为调整广西甘薯生产的品种结构提供了参考。

[Objective] The aim of the research was to screen vinevegetable sweetpotato with high-yield,good quality and strong resistance and lay the foundation for its extension and application in the production.[Method] Based on national regional experiment of vine-vegetable sweetpotato varieties,the stem-leaf yields of 7 sweetpotato varieties such as Fushu 10,Fushu 11,Guangshucai 1,Guangshucai 2,Fucaishu 1,Pushu 53 and Fushu 7-6（CK） were determined and the qualities were identified.[Result] Compared with CK,the stem-leaf yields of all tested varieties were increased.The yield of Fushu 10 was highest,with the yield per unit area being 29 599.5 kg/hm^2,and 41.3% higher than CK.The following were Pushu 53 and Guangshucai 2,with the yield per unit area being 26 899.5 and 26 850 kg/hm^2,and 28.4% and 28.2% higher than CK respectively.Except Fucaishu 1,the quality identifications of other sweetpotato were better and suitable for planting in Guangxi.Top 3 in comprehensive ranking were Fushu 10,Pushu 53 and Guangshucai 2.[Conclusion] The research provided references for regulating the variety structure in sweetpotato production.
