Abstract
The existence of local varieties of potatoes for the processed industry in Indonesia is very necessary, most of the raw materials for the potato chip industry are still imported. Even for French fries, one hundred percent is still imported. Selection of 30 potato clones was conducted at the Margahayu Experimental Field (1250 m asl), in Lembang from January to May 2016. It used a completely randomized block design with 3 (three) replications which every plot consisted of 10 plants. The evaluated characters included plant vigor, plant height (cm), stem diameter (mm), tuber weight (g), percentage of consumption tuber (%), yield (ton/ha), specific gravity (Sg), tuber shape, tuber skin color, tuber flesh color and appearance of tuber skin. Analysis of variance showed that all quantitative characters were very significantly different (P <0.01). Clone 15.33 showed the highest tuber yield per plant (831 grams/plant) which was significantly different from the comparable variety of Atlantic (166 grams/plant). The highest percentage of consumption tubers was obtained from clones 15.26 (75.3%) which were significantly higher than comparable varieties (Amabile, Granola, Medians and Atlantic). The result suggested that 2 (two) clones e.g. 15.33 and 15.23 with specific gravity (Sg) higher than 1.067 are potential to be used for industrial potato chips.
