Propagation of potato seeds in vitro in various varieties and planting media

Potato is one of the horticultural commodities that has a very important role as an alternative food ingredient. Efforts to increase potato productivity begin with providing quality seeds. One of the superior seed procurement techniques is the use of stem cuttings to increase the number of seedlings. This study aims to determine the effect of varieties and planting media on the propagation of potato seeds. The study consisted of 3 varieties, namely Granola L, AR 08 Agrihorti, AR 07 Agrihorti and 4 types of planting media, namely rice husk charcoal, rice husk charcoal + compost, rice husk charcoal + cocofeat + compost, rice husk charcoal + rotten rice husk + compost. The combination of treatments was applied to a two-factor factorial study arranged based on a completely randomized design with three replications. The results showed that the Granola L variety gave better results on the length of the apical shoots of potato seedlings, namely 56.33 mm and the number of shoots, namely 3.58 pieces. The AR 07 Agrihorti variety gave better results on the length of lateral shoots, namely 78.11 mm and the number of lateral shoot cuttings, namely 4.69 stems. The planting media of rice husk charcoal + rotten rice husk + compost gave better results on the length of apical shoots, which was 65.93 mm, the length of lateral shoots was 83.41 mm, the number of shoots was 3.22 pieces and the number of lateral shoot cuttings was 4.74 stems. The Granola L variety planted on rice husk charcoal + rotten rice husk + compost gave better results on the number of potato seed segments from in vitro, which was 3.44 pieces. published by the International Journal of Agronomy and Agricultural Research (IJAAR)
