Abstract

Sweet potato (Ipomoea batatas L.) is an important food crop in Indonesia with high potential to support food diversification, improve nutrition, and develop functional food products. The purple-fleshed variety (Ayamurasaki) is used as the female parent in breeding programs due to its high anthocyanin content. This study aimed to analyze the vegetative morphological characteristics, yield potential, and chemical composition of open-pollinated sweet potato lines using Ayamurasaki as the female parent. This study was conducted using a Randomized Block Design (RBD) consisting of five lines, namely A19, A23, A39, A74, A84, and the Ayamurasaki variety as a control, with three replications. Observations were made on vegetative morphological parameters, tuber weight per plant, and chemical composition analysis. The results showed significant variations among the tested genotypes for all observed parameters. The A23 line showed superior performance, characterized by larger leaf size, larger stem diameter, high yield, and the highest anthocyanin content. Meanwhile, the A84 line showed potential for industrial use due to its relatively high carbohydrate and starch content. These findings provide valuable information for the further development of superior sweet potato lines with high productivity and better nutritional value to support future breeding programs.

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
