Alternative Potential of Various Processed Potato Varieties in the Highland

Abstract

The low production of Atlantic as processed variety has prompted efforts to introduce varieties as well as the creation of new varieties. The purpose of this study was to examine various alternatives of processed potato varieties that have the potential in the highlands of Garut, West Java. The research was conducted in Cikajang, Garut, West Java, from December 2017 to March 2018. The research used a randomized block design with eight varieties and four replications. The varieties tested were Blis, Atlantic M., Medians, Granola L, AR8, AR7, Amabile, and Atlantic. The observed variables were height plant at 2, 4, 6, and 8 WAP, number of tuber by size, and tuber weight. The data was tested with the F test and if it was significantly different, it was continued with the orthogonal contrast test at the 5% level. Heatmap analysis was performed using the R Studio program The result showed that Granola was not significantly different from all processed varieties. There were three groups of processed varieties, namely the first group, Amabile. The second was AR 7, Medians, and Blis. The third was Atlantic M, Atlantic, and AR 8. Amabile variety had the highest production and number of large tubers.
