摘要/Abstract

摘要： 通过对金薯17、金薯20、福宁紫4号、福宁紫5号、龙紫4号、龙紫6号、龙紫9号7个优质紫甘薯[Ipomoea batatas （L. ） Lam）]新品种的产量和性状等进行比较试验,以福宁紫3号为对照,为其在福建省的生产应用提供科学依据。结果表明,龙紫9号产量为46.52 t/hm²,比对照增产22.4%,居第一位;金薯20也表现了突出的丰产性能,产量达42.35 t/hm²,比对照增产11.4%,位列各参试品种的第二位;金薯17产量为39.17 t/hm²,仅比对照增产3.1%;且这3个品种薯块外观好,薯皮紫红色,薯肉紫色,丰产性状好,其中龙紫9号、金薯20产量与对照品种差异达显著或极显著水平,适宜在该地种植推广。其他品种产量都低于对照,其中龙紫6号和龙紫4号与对照品种差异达显著或极显著水平。

Abstract: The yield and characters of seven new purple sweet potato varieties with high quality, including Jinshu 17, Jinshu 20, Funingzi No.4, Funingzi No.5, Longzi No.4, Longzi No.6 and Longzi No.9, while taking Funingzi No.3 as control variety,were compared, in order to provide scientific basis for its production and application in Fujian province. The results showed that the yield of Longzi No.9 was 46.52 t/hm², which was 22.4% higher than control, and ranked the first, and the yield of Jinshu 20 was 42.35 t/hm², which was 11.4% higher than control, and ranked the second among all varieties tested. The yield of Jinshu 17 was 39.17 t/hm², which was only 3.1% higher than control. And these three varieties had good appearance with purple skin, purple meat and high-yield character. The yield of Longzi No.9 and Jinshu 20 was siginifacnt higher than contol variety, so these two vareites was suitable for local planting. The yield of other varieties was all lower than control, the yield of Longzi No.6 and Longzi No.4 was significant or extremely significant lower than control.
