Abstract

The difficulty of obtaining industrial potato varieties that can produce high production and relatively resistant to certain pests and diseases is one of the inhibiting factors for industrial potatoes in Indonesia. The selection of potato clones were expected to produce clones that produce high production and are relatively resistant to certain pests. Twelve potato clones were selected in the Experimental Field of PT. AIMS located at Cinta Village, Karang Tengah District, Garut Regency from May to September 2021. A Randomized Complete Design (RCBD) consisting of twelve treatments and each treatment with five replications were used. The results of the study showed that two clones (Clone–1 and Clone–5) had high yield potential. Clone–1 and Clone–5 produced the highest number of tubers and bulb weights compared to other clones. Clone–5 also showed moderate response to Phytophthora infestants and resistance to Fusarium sp., and show resistance response to insect pests such as Spodoptera litura, Liriomyza sp, and Thrips sp. However, Clone–1 showed a susceptible response to wilt and blight diseases as well as the three species of insect pests. The results of this study concluded to consider the use of Clone–1 and Clone–5 as potato tuber propagation soon.

一种潜在的马铃薯克隆选择，对外来植物入侵有机体的攻击做出反应

难以获得高产且对某些病虫害具有相对抗性的工业马铃薯品种，是印度尼西亚工业马铃薯的抑制因素之一。马铃薯无性系的选择希望产生高产和对某些害虫具有相对抗性的无性系。于2021年5月至9月在Garut Regency Karang Tengah区Cinta村PT. AIMS试验田选择了12个马铃薯无性系。采用随机完全设计(RCBD)，包括12个处理，每个处理5个重复。结果表明，克隆1号和克隆5号具有较高的产量潜力。与其他无性系相比，无性系1和无性系5产生的块茎数量和鳞茎重量最高。克隆- 5对疫霉有中度反应，对镰刀菌有抗性，对斜纹夜蛾(Spodoptera litura)、Liriomyza sp.、Thrips sp.等害虫有抗性反应，而克隆- 1对枯萎病和枯萎病以及这三种害虫均有敏感反应。本研究结果表明，近期可考虑利用克隆1号和克隆5号进行马铃薯块茎繁殖。
