Morphological characteristics and yields of several sweet potato (Ipomoea batatas L.) tubers

Abstract

This study aims to evaluate certain tubers of new sweet potato clones for their morphological characters of and yield under low input conditions in the middle highland. This study was conducted at Saree, Aceh Besar, the Province of Aceh (485 m ASL) from February to July 2015. The study used a Completely Randomized Block Design of non-factorial with 12 sweet potato clones consisting of nine clones passed by CIP-SEA Bogor, Indonesia (CIP-LSQ, CIP-1945, CIP-MAN, CIP-513, CIP-BDG, CIP-WHI-5, CIP-W86P, CIP-B9, and CIP-204), one national variety (Antin-1), and two local clones (Orange Saree and Purple Saree). The results showed that there were differences in the characters of 12 sweet potato clones in terms of their tuber shapes, skins and flesh colors. Sweet potato tuber shape being studied consisted of an oval, round and long. Tuber flesh color generally was white, cream, yellow, orange and purple. Meanwhile, CIP-1945, CIP-W86P, Local Orange Saree clones, and Antin-1 variety have orange tuber flesh. CIP-WHI5 clone has the highest number of tubers, while CIP-204 clone has the largest diameter and length of tubers, and the highest in tuber yield.

Utilization of rice straw waste compost to increase growth and production of local sweet potatoes

“…Differences in sweet potato yields can be influenced by genetic conditions of the plant, the environment in which cultivation is carried out, the technical culture applied. The results of this study are in line with [5] who found that the effect of genotype, environment or genotype interaction with the environment was significant on sweet potato yields.…”

“…To get the best sweet potato production, it is very important to choose varieties that are suitable for environmental conditions. [5]. This study aims to determine the potential for growth and production of local genotypes of sweet potato if cultivated in a different location from the area of origin and the response to rice straw compost.…”

Growth Parameters and Yield Evaluation of Tropical and Temperate Sweetpotato Genotypes Under Acid Soil Conditions

“…The results of our study are close to the findings of Kareem (2013) where the yield of storage roots of different genotypes of sweetpotato ranged from 5.43 to 10.90 t ha -1 . We also observed the correlation of higher tuber fresh weight with higher tuber yield that was reported by Hayati et al (2020) and Hossain et al (2018).…”

“…That's why its cultivation could not reach its maximum yield potential, resulting in lower yield production. The morphological and yield contributing characteristics like leaf area, leaf production, leaf photosynthesis, tuber formation and development, total dry matter production, and tuber yield depend on genetic and environmental factors (Hayati et al, 2020). For improving sweet potato varieties, the analysis of genotypes at the genetic level with agro-morphological traits (Mahmud et al, 2021;Rosero et al, 2020) can provide more information that will be helpful for the plant breeders.…”

“…The shape of the storage root was fusiform or globose or elliptical. Among the nine sweetpotato genotypes, JSP 1, JSP 2, JSP 4, BARI SP Different skin colours of sweet potato tuber have been reported as white, yellow, red, pink, orange, cream and dark purple by Hayati et al (2020).…”
