Abstract

Purple sweet potato farming in Banyuwangi as a mainstay commodity to support farmers' income. The local variety TW became the preferred local variety, but farmers began to complain about the decline in productivity. These problems need an effort to improve the use of local varieties in the use of superior varieties in restoring the productivity level of purple sweet potato to its original state. Thus, it is necessary to dame plots of prospective superior varieties to obtain farmer's assessment and preferences before purple sweet potato clones are released into varieties that have legality as VUB. The results showed that farmers and traders liked the skin and tuber shape of MSU 1001-15 and MSU 1002-07 clones. The reasons farmers chose the two clones were because: 1) they had a bright color and rather thick skin, 2) the shape of the large tubers was not too round and elongated, and the yield was high. The value of purple sweet potato farming in Banyuwangi is economically feasible in terms of marketing and income value which has a significant advantage.

Abstract

Sweet potato (Ipomoea batatas L.) is one of the alternative commodities in food diversification. Apart from being a source of carbohydrates, orange-fleshed sweet potatoes contain lots of beta-carotene (pro-vitamin A) and antioxidants that contribute greatly to health. Efforts to improve the quality of orange sweet potatoes in quantity and quality are still very much needed, one of which is by crossing. The study aimed to obtain high-yielding orange-fleshed sweet potato lines from free crosses between female parent Beta-2 and male parent local sweet potato Lampung (LPG-01, LPG-03, LPG-06, LPG-11), Cilembu, Ayamurasaki. The method used in this selection is a single planting selection method by looking at the morphological characters of each line. Single planting selection is the initial selection after successful crossing. The results showed that of the 79 lines that were crossed by a female parent of Beta-2, there were 19 lines with orange flesh and high yields, namely Beta2 OP1, Beta2 OP3, Beta2 OP4, Beta2 OP6, Beta2 OP8, Beta2 OP19, Beta2 OP25, Beta2 OP30, Beta2 OP33, Beta2 OP34, Beta2 OP36, Beta2 OP38, Beta2 OP42, Beta2 OP43, Beta2 OP54, Beta2 OP58, Beta2 OP63, Beta2 OP73, Beta2 OP77
