Abstract

Potatoes (Solanum tuberosum L.) are one of carbohydrates source which is interested, but its national production and yield are still low. Efforts to increase potato production are by developing new varieties with higher yield. This study aimed to evaluate the yield potential of IPB genotypes potato in Garut district, West Java. The study was conducted in Girijaya Village, Cikajang District, Garut Regency, West Java in November 2020 to March 2021. This study uses a completely randomized Complete Group Design (RKLT) namely genotypes and three replications as a group. The planting material used are the potato genotype PKHT-2020-006, PKHT-2020-010, PKHT-2020-012, PKHT-2020-016, PKHT-2020-017, PKHT-2019-021, as well as Medians and Granola potato varieties as a comparison. The results showed that genotypes of PKHT-2020-012 and PKHT-2019-021 had the highest productivity than the comparison varieties. The others genotype that have productivity not different with comparison varieties is genotype of PKHT-2020-010.
