Micropropagation of potato (Solanum tuberosum L.) var. Atlantic on various culture media composition
AbstrakPotato is included in one of the three most important crops globally after paddy andwheat because it contributes to staple food for humans around the world. In Indonesia, potatoprioritizes its development because of non-rice carbohydrate sources and potential in fooddiversification programs. In Lampung, potato productivity decreased significantly from 2017to 2018, resulting in a negative growth rate (-33%). One of the factors that cause the lowproductivity of potatoes is the limited availability of superior seeds. Micropropagation can bean alternative to solve this problem. This research aimed to investigate the growth response ofpotato var Atlantic on various culture media and obtain the most appropriate culture media forpotato shoots induction and multiplication. This research was conducted at the Plant TissueCulture Laboratory, Politeknik Negeri Lampung, from June—September 2020. Treatmentswere single arranged in a completely randomized design with three replications, and eachreplication consisted of three culture bottles containing one explant. Data analysis usingANOVA and HSD test in 5 % alpha. Based on the result of this research, it can be concludedthat the potato var Atlantic culture showed different responses on the various components ofculture media, and MS media with 0.5 mg l2-iP is the most appropriate culture media forpotato micropropagation.
