ABSTRACT Sweet potato (Ipomoea batatas) spreads mainly by vegetative propagation, and therefore this vegetable may have duplicate accessions in germplasm banks. The authors aimed to characterize morpho-agronomically the sweet potato germplasm from the Active Germplasm Bank (AGB) of Universidade Federal de Sergipe (UFS).The experiment was carried out at the Research Farm “Campus Rural da UFS”. The experimental design was a randomized block design, testing 73 sweet potato accessions with two replicates and four plants per plot. Morpho-agronomic traits of aboveground part and roots were evaluated. We observed that the leaf lobe type, the number of lobes per leaf, shape of central lobe, and general leaf shape were traits which provided the most variability among the accessions. For damage caused by soil insects, 52 accessions showed tolerance. The accessions presented a range from 0.33 to 2.71 t/ha for dry mass of aboveground part and from 1.20 to 10.89 t/ha for the total productivity of the roots. The high phenotypic variability of this crop shows good prospect for breeding programs.

The phenotypic diversity of sweet potato (Ipomoea batatas) landraces was assessed using morphological traits, verifying how this diversity is distributed among the households and settlements of the Vale do Ribeira, Brazil. A total of 74 accessions, involving 53 landraces, collected from 30 households distributed among 18 settlements that practice traditional agriculture in the municipalities of Iguape, Ilha Comprida, and Cananeia, as well as four commercial varieties acquired in markets of Iguape and Piracicaba, were evaluated under an ex situ experimental condition in Piracicaba, SP, Brazil. Nine phenological and floral descriptors, nine morphological vegetative aerial descriptors and five storage root traits were recorded. The 14 aerial vegetative and root descriptors were evaluated as binary data, totaling 74 attributes. Cluster analyses were made using the Jaccard similarity index and the UPGMA (unweighted pair group method with arithmetic mean) agglomerative method. Binary data was also submitted to a variance analysis (AMOVA). No defined groups were observed, indicating that the diversity of the landraces is not structured in space, but considerable morphological variation was found in this area (Jaccard similarity index varying from 0.12 to 1.0). Most of the variability occurred within households (64.4%), followed by the distribution among households within settlements (27.1%) and among settlements (8.4%). Thus, the traditional agriculturists of Vale do Ribeira maintain a high morphological diversity for sweet potato within their households, which can be assumed to be produced by the outcrossing mating system of this species and somatic mutation events, as well as the exchange system at local and regional levels.

AbstractLeaf shape, a spectacularly diverse plant trait, varies across taxonomic levels, geography, and in response to environmental differences. However, comprehensive intraspecific analyses of leaf shape variation across variable environments is surprisingly absent. Here, we perform a multi-level analysis of leaf shape using diverse accessions of sweetpotato (Ipomoea batatas), and uncover the role of genetics, environment, and GxE on this important trait.We examine leaf shape using a variety of morphometric analyses, and complement this with a transcriptomic survey to identify gene expression changes associated with shape variation. Additionally, we examine the role of genetics and environment on leaf shape by performing field studies in two geographically separate common gardens.We show that extensive leaf shape variation exists withinI. batatas, and identify promising candidate genes underlying this variation. Interestingly, when considering traditional measures, we find that genetic factors are largely responsible for most of leaf shape variation, but that the environment is highly influential when using more quantitative measuresvialeaf outlines.This extensive and multi-level examination of leaf shape shows an important role of genetics underlying a potentially important agronomic trait, and highlights that the environment can be a strong influence when using more quantitative measures of leaf shape.

In Situ Characterization

Morphological characters of above ground plant parts can be used to distinguishsweet potato accessions. The objective of this study was to get a number of diversity of sweet potato accessions based on above ground part morphology and to determine the accuracy of in situ characterization. This study used a survey method in five villages in two sub-districts, namely Inomosol and Huamual Muka, Western Ceram District. The first stage of this study involved in situ characterization, and the second stage involved planting and ex situ morphological characterization of 2-month-old plants which was used sweet potato descriptors. Data were analyzed descriptively and qualitatively. The results showed that there were 25 accessions of sweet potato found in Huamual Muka and Inomosol Sub-districts, as distinguished by leaf shape and color, leaf patterns and leaf lobe number, petiole and stem colors, and vine twisting tendency. Verification results of the above ground morphology showed accuracy of ≥80% in 3 phenotypes in leaf lobe pattern, shape of central leaf lobe, linear middle leaves, leaves with 1, 5 and 7 lobes, green abaxial leaf veins, 2 petiole color phenotypes, purplish red stem, and stem additional colors. Meanwhile, the accuracy of characterization of other phenotypes was 0-76%.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (<em>x̅</em>= 232,50).</p><p>The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.</p><p> </p><strong>Keywords: </strong>Liver, <em>Ipomoea batatas</em> L., Malondialdehyde, Anthocyanins

<em>Sweet potato is an important staple food crop especially for the local people of Central Highlands Jayawijaya. There are many accessions that have always been maintained its existence to enrich their various uses. Traditionally, sweet potato accessions were grouped based on the utilization, such as for animal feed, cultural ceremonies, consumption for adults, as well as for infants and children. This study was aimed to analyze the nutritional value of sweet potatoes consumed by infants and children of the Dani tribe. Chemical analyses were conducted at the Laboratory of Post-Harvest Research and Development Center, Cimanggu, Bogor. The results showed that each of 4 (four) sweet potato accessions which were consumed by infants and children had good nutrient levels. Accession Sabe showed the highest water content (72.56%), vitamin C (72.71 mg/100 g), Fe (11.85 mg/100 g), and K levels (130.41 mg / 100 grams). The highest levels of protein (1.44%), fat (1.00%), energy (154.43 kkal/100 gram), carbohydrate (35.47%), starch (30.26%), reducing sugar (3.44%), riboflavin (0.18 mg/100 g), and vitamin A (574.40 grams IU/100 were produced by accession Manis. On the other hand, accession Saborok produced the highest value for ash content (1.32%), vitamin E (28.30 mg/100 g), and ?-carotene (64.69 ppm). The highest level of crude fiber (1.81 %) and thiamin (0.36 mg/100 g) was produced by accession Yuaiken.</em>
