甘薯新品种南安点区域试验

Regional Test of the New Varieties of Sweet Potato in Nan′an City

2016年引进27个甘薯新品种开展区域试验,27个品种分为紫色组、食饲兼用型组、优质淀粉型组3个组别。试验结果表明:紫色组中金薯14和福薯317平均每667 m^2产量分别比对照福宁紫3号增产92.6、80.0 kg,差异达显著水平;金薯14薯形长纺锤形,薯皮紫红色,薯肉紫色,高抗蔓割病;福薯317薯形长纺锤形,薯皮、薯肉紫色,中抗蔓割病。食饲兼用型组中的福宁薯20号和龙薯35号平均每667 m^2产量分别比对照金山57增产448.6、410.7 kg,差异达极显著水平;福宁薯20号薯形长纺锤形,薯皮薯肉白色,高抗蔓割病;龙薯35号薯形下纺锤形,薯皮薯肉桔黄色,中抗蔓割病。优质淀粉型组中莆薯12号和福宁薯21号平均每667 m^2产量分别比对照广薯87增产305.3、289.3 kg,差异达极显著水平;莆薯12号和福宁薯21号薯形均为长纺锤形,薯皮红色,薯肉黄色,其中莆薯12号中抗薯瘟病。以上6个甘薯新品种可在南安市进一步扩大试验、示范。

In 2016,27 new varieties of sweet potato were introduced to carry out the regional test,and the 27 varieties were divided into three groups:the purple group,feeding group,and high-quality starch group.The results showed that the average yield per 667 m^2 of Jinshu 14 and Fushu 317 in the purple group respectively increased by 92.6 kg and 80.0 kg compared with the control group of Funingzi No.3,with significant differences.Jinshu 14 was long spindle-shaped,with magenta skin and purple flesh,and had high resistance to the stem rot of sweet potato;while Fushu 317 was long spindle-shaped,with purple skin and flesh,and had moderate resistance to the stem rot of sweet potato.The average yield per 667 m^2 of Funingshu No.20 and Longshu No.35 in the feeding group respectively increased by 448.6 kg and 410.7 kg compared with the control group of Jinshan 57,with extremely significant differences.Funingshu No.20 was long spindle-shaped,with white skin and flesh,and had high resistance to the stem rot of sweet potato;while Longshu No.35 was long spindle-shaped,with orange skin and flesh,and had moderate resistance to the stem rot of sweet potato.The average yield per 667 m^2 of Pushu No.12 and Funingshu No.21 in the high-quality starch group respectively increased by 305.3 kg and 289.3 kg compared with the control group of Guangshu 87,with extremely significant differences.And Pushu No.12 and Funingshu No.21 were both long spindle-shaped,with red skin and yellow flesh.Among them,Pushu No.12 had moderate resistance to sweet potato blast.The above six new varieties of sweet potato could be further expanded for the experiment and demonstration in Nan′an City.
