Abstract Background Sweet potato is an important food crop in China which is the fifth largest staple crop next to rice, wheat, maize, and soybean. Recent years the destroy infecting by DNA viruses in sweet potato was more and more serious. Three DNA viruses (sweepoviruses, Badnavirus and Mastrevirus) are major agents in viral diseases of sweet potato in China. It is necessary to establish a rapid and efficient method to evaluate the health of sweet potato seedlings and tubers,which will greatly affect the yield, quality of tubers and seeding circulation of sweet potatoes. Sweepoviruses were a group phylogenetically distinct from other begomoviruses that infects plants of the family Convolvulaceae including sweet potato. Sweet potato symptomless virus 1 (SPSMV-1) is the only species of Mastrevirus which can infected sweet potato. Sweet potato Badnavirus B (SPBV-B) are non-enveloped bacilliform DNA viruses with a monopartite genome which belonged to the genus Badnavirus of the family Caulimoviridae and was first found in sweet potato in 2009. As the mixed infection of these viruses is very common, rapid detection is required for etiologic diagnosis. Results In this study, a rapid and efficient method to evaluate the infection of major DNA viruses (sweepoviruses, Badnavirus and Mastrevirus) in sweet potato seedlings and tubers was developed and applied. A mixture of three pairs of primers was used for amplification of viral nucleic acids, yielding three different amplicons with sizes of 750 bp, 147 bp and 396 bp for sweepoviruses, Badnavirus and Mastrevirus respectively. The specificity and sensitivity of multiplex PCR were also evaluated. A total of 65 sweet potato samples with virus-like symptoms cuttings and storage roots from Henan province in China were collected between June 2019 and July 2021. They were tested for the presence of three DNA viruses by multiplex PCR which showed sweepoviruses, Badnavirus and Mastrevirus infections were 60.0%, 36.7%, and 43.3% respectively. Co-infections with three viruses, sweepoviruses and Badnavirus, sweepoviruses and Mastrevirus, Badnavirus and Mastrevirus were identified in different samples (the detection ratio of co-infections was 13.3%, 20.0%, 13.3%, and 10.0% respectively). Conclusions In the current situation of frequent virus mixed infection in sweet potatoes, this method is the first report on a simple assay and may be a potentially useful for apid and efficient method to evaluate the infection of major DNA viruses in sweet potato seedlings and tubers in China.

Arbuscular mycorrhizal fungi (AMF) represent a functionally important component of soil microbial community, being of particular significance for plant mineral nutrition in tropical agro ecosystems. The effects of AMF inoculation on growth and yield of two sweet potato varieties was studied during the short rains season of 2017/2018 in the Teaching and Research Farm of Agricultural Science and Technology Department, Kenyatta University. The experiment was laid down as 2x2 factorial design in a randomized complete block design (RCBD) with three replications. The experimental factors were two sweet potato varieties (Kemb-10 and Bungoma) and AMF inoculum (With and without inoculation). Data on growth parameters was collected on vine length and number of branches, while data on yield was collected on marketable storage roots and shoot biomass. Data was analyzed using Genstat 15th edition and the results showed that there was significantly difference at P≤0.05 among the treatments. AMF inoculation increased growth and yield of sweet potatoes by vine length 29.74%, Number of branches 22.36%, marketable storage roots 18.32%, and shoot biomass 28.68% in week 20. Also, variety interacting with AMF inoculation enhanced growth and yield parameters. In conclusion, the study demonstrated that the application of commercial AMF inoculum solely or when interacting with varieties enhanced growth and yield of sweet potatoes, though there was no significant difference between the two varieties.

Annual Herb

The sweet potato (Ipomoea batatas) is an annual herb of the family Convolvulaceae and ranked as the world's seventh most important food crop with a major contribution to energy and phytochemical source of nutrition. Three different conditions of sweet potatoes are unpeeled tuber (UPSP), peeled tuber (PSP) and skin of tuber (SSP). The objective of this study is to evaluate the phytochemical availability (total phenolic contents (TPC), total flavonoid contents (TFC) and anthocyanin content) in the different parts of the sweet potato tuber. Folin-Ciocalteau (FC) assay showed that phenolic contents for UPSP (41.14±1.69 mg GAE/100 g dry basis) and PSP (42.24±2.19 mg GAE/100 g dry basis) were significantly (50%) higher than SSP (26.01±2.04 mg GAE/100 g dry basis). In terms of flavonoid content, the highest value was retained in PSP (9.55±0.82 mg quercetin/100 g dry basis) followed by UPSP (3.30±0.19 mg quercetin/100 g dry basis) and SSP (1.43 ± 0.03 mg quercetin/100 g dry basis). PSP (9.43±0.08 mg/100 dry basis) had a higher anthocyanin content compared to UPSP (5.21±0.02 b mg/100 g dry basis) and SSP (5.21±0.02 b mg/100 g dry basis). The phytochemical properties were available in all conditions of the sweet potato. However, PSP was suggested to be the most preferable condition for further processing in the sweet potato industry.

The potential of the sweet potato as a food source for future long-term manned space missions is being evaluated for the National Aeronautics and Space Administration's (NASA) Controlled Ecological Life Support System (CELSS) Program. Several experiments have shown that the sweet potato can be grown hydroponically. However, an evaluation of the NASA fan-shaped Biomass Production Chamber (BPC) channel was initiated to determine if channel depths influenced the yield of hydroponically grownsweet potatoes. Three channel depths were studied, 5 cm (2 in) standard NASA BPC channel, 10 cm (4 in) channel and 15 cm (6 in) channel. The experiment consisted of one replication. The results show that channel depth does effect the yield of storage roots. The 15 cm depth channel provided the most consistent yield with all channels having significantly different fresh storage root yields in the replicate.

Skin Quality

Sweet potato (Ipomoea batatas) growth faces two critical problems: variability in storage root (SR) number and size among individual plants, and skinning injuries that render the SR susceptible to pathogen infections during storage. We hypothesized that application of potassium (K) fertilizer, an essential mineral for sweet potato, would contribute to increased yield, uniformity, and skin quality of SRs. Sweet potatoes were grown in sandy soil, which is poor in K, and in loess soil. The fertilizers potassium chloride (KCl) and polyhalite were applied before planting. Polyhalite is a hydrated sulfate of K, calcium, and magnesium that has been shown to improve potato skin appearance. Soil type was the major factor affecting SR yield—higher in sandy vs. loess soil. The K fertilizers did not affect yield in either soil type, or improve SR uniformity. However, the skin of the SRs from loess soil had more phellem layers and larger phellem cells following fertilization, mainly with KCl. Accordingly, the expression of suberin marker genes was significantly higher in mature vs. immature skin of SRs fertilized with KCl. Overall, soil type was the major factor affecting sweet potato yield, and addition of K positively affected skin morphology and related gene expression.

Directional Growth

Volatiles released from sweet potato storage root tissue infected by different sweet potato storage root pathogens stimulated eruptive germination of sclerotia of Sclerotium rolfsii but did not influence the direction of hyphal growth on agarose. Volatiles from healthy sweet potato storage root tissue did not affect percent hyphal or eruptive germination of sclerotia of S. rolfsii but stimulated directional growth of hyphae toward the healthy tissue. In laboratory experiments, the frequency of infection of sweet potato stem segments by S. rolfsii on the surface of natural soil was increased when sclerotia were incubated in the presence of decaying sweet potato storage root tissue. Incidence of sclerotial blight lesions on sprouts in plant beds was increased in the presence of roots infected by Fusarium solani or Erwinia chrysanthemi. Volatiles from decaying sweet potato mother roots may predispose sweet potatoes to sclerotial blight.

Sweet potato is an increasingly significant crop and its effective and sustainable cultivation has become important in temperate countries. The purpose of this pilot study was to investigate the effects of a mycorrhizal inoculum, Symbivit, and whether it could establish a symbiotic relationship with the seedlings of two sweet potato varieties (orange and purple). The effectiveness of the mycorrhizal inoculation with a sterilized substrate on the mycorrhizal parameters (F%, M%, m%, a%, A%) and physical parameters “[length of roots and shoots (cm), the fresh weight of shoots and roots (g) as well as the length of stem (cm)]” on the sweet potato seedlings has also been studied. Results show that the sterilization treatment with Symbivit in both varieties increased the frequency of mycorrhiza in the root system. For the intensity of the mycorrhizal colonization in the root fragments and the arbuscular abundance, there was a difference between the mycorrhizal inoculum and the sterilization treatment among the varieties. Overall, the preliminary results provided remarkable information about mycorrhizal inoculation, substrate sterilization on mycorrhizal development, as well as changes in the physical parameters between sweet potato seedlings. Our results could serve as a practical strategy for further research into adding significance to the effect of the beneficial soil microbes on sweet potatoes.

Sweet potato is the 11th most important food crop in the world and an excellent source of nutrition. Postharvest diseases were monitored in sweet potato storage roots collected from the local markets in Korea during 2021. Several diseases including Fusarium surface and root rot, charcoal rot, dry rot, and soft rot were observed in the postharvest sweet potatoes. A total of 68 fungal isolates were obtained from the diseased samples, and the isolates were grouped into 8 different fungal colony types. Based on multilocus phylogeny and morphological analysis of 17 representative isolates, the isolates were identified as Fusarium oxysporum, F. ipomoeae, F. solani, Penicillium citrinum, P. rotoruae, Aspergillus wentii, Mucor variicolumellatus (Mu. circinelloides species complex), and Macrophomina phaseolina. F. oxysporum was the predominant pathogen as this is the most common pathogen of sweet potato storage roots causing the surface rot disease, and M. phaseolina caused the most severe disease among the pathogens. Dual culture antagonistic assays were evaluated using Trichoderma harzianum strains CMML20–26 and CMML20–27. The results revealed that the two strains showed strong antifungal activity in different ranges against all tested pathogens. This study provides an understanding of diverse postharvest diseases in sweet potatoes and suggests potential biocontrol agents to manage the diseases. In addition, this is the first report of sweet potato storage root rot diseases caused by A. wentii, and P. rotoruae worldwide.

Sweet Potato Virus

Sweet potato chlorotic stunt virus (SPCSV), a crinivirus in the family Closteroviridae, is a quarantine pest in Europe and one of the most economically important viruses of sweet potato (Ipomoea batatas (L.) Lam) crops globally. It forms synergies with other viruses in sweet potato, leading to yield loss of 30-100% (Qin et al., 2014). In summer 2020, 62 symptomatic and 38 symptomless sweet potato vines were randomly collected in farmers’ fields in the south (Ásotthalom, Szeged) and central (Galgahévíz) parts of Hungary and transplanted in an insect-proof greenhouse. Six of the plants expressed SPCSV-like symptoms, including stunting, vein clearing and leaf purpling (Suppl1). To check for common viruses of sweet potato (Suppl2), total RNA and DNA were extracted from leaves of each of the 100 plants using Trizolate reagent (UD-GenoMed, Debrecen, Hungary) and Zenogene kit (Zenon Bio, Szeged, Hungary), respectively. Primer pair Ch2N (Suppl2) was designed using Primer3 (v. 0.4.0) to amplify a 194 bp fragment of SPCSV RNA1. Presence of the RNA viruses was checked by qPCR using qPCRBIO SyGreen 1-step qPCR kit (PCR Biosystems, London, UK), while DNA viruses were checked by PCR using DreamTaq DNA Polymerase (Thermo Scientific, Vilnius, Lithuania), followed by 1% agarose gel electrophoresis. Four samples (labelled A5.1, A6.1, A6V9-1, A6V9-2) out of the 100 tested positive for SPCSV. Two of them (A6V9-1 and A6V9-2) were co-infected with SPCSV, a badnavirus sweet potato pakakuy virus (SPPV) and a potyvirus sweet potato virus 2 (SPV2), while the other two (A5.1 and A6.1) lacked SPV2. Plants infected with SPCSV, SPV2 and SPPV displayed more severe symptoms. To confirm the results, cDNA synthesized from the four SPCSV positive samples using RevertAid first strand cDNA synthesis kit (Thermo Scientific, Vilnius, Lithuania) underwent PCR (94oC 4 min, 94oC 1 min, 53oC 30 s, 72oC 70 s and 72oC 10 min for a total of 30 cycles) using primers CL43U and CL43L for the viral heat shock protein 70 gene (Maliogka et al., 2020). An expected band size of 486 bp was obtained in all cases. The amplicon from sample A6.1 was sequenced and found to be identical to SPCSV Guatemalan isolate GT:B3:08 (acc. JF699628). RNA1 and RNA2 complete sequences from sample A6.1 were obtained via PCR amplifications of cDNA using primers (Suppl2) designed (from acc. KC888966 for RNA1 and acc. KC888963 for RNA2) to amplify overlapping fragments of West African strain of SPCSV. QIAquick gel extraction kit (QIAGEN, Hilden, Germany) was used to purify the PCR fragments, which were then cloned into pGEM-T Easy Vector (Promega, Madison, USA) and sequenced using Sanger sequencing technique (Biomi, Gödöllő, Hungary). BLASTn search revealed that RNA1 of our isolate Hun_01 (acc. MW892835) had 99.63% sequence identity to SPCSV isolate su-17-10 (acc. MK802073), while RNA2 of Hun_01 (acc. MW892836) was 99.68% similar to SPCSV isolate min-17-1 (acc. MK802078) and isolate 24-1 (acc. MK802080). Phylogenetic analysis using MegAlign (v. 7.1.0, 44.1) showed a close relationship between our isolate and those isolated in China, suggesting that they may have a common origin (Suppl1). Severe stunting and leaf yellowing symptoms developed in I. setosa indicator plants grafted with SPCSV infected sweet potato scions. qPCR test for the virus confirmed its presence in the I. setosa leaves. To the best of our knowledge, this is the first report on the occurrence of SPCSV in Hungary and the third in Europe (Valverde et al. 2004; EPPO 2021).

В 2017–2019 годах изучены сортообразцы сладкого картофеля на староорошаемых лугово-сероземных почвах Зарафшанской долины. Цель исследований – комплексная оценка сортообразцов батата в условиях Зарафшанской долины по скороспелости, росту, развитию, интенсивному размножению, формированию урожая, компактности клубней в гнезде, продуктивности, урожайности и лежкости клубней и выделение из них перспективных, а также разработка приемов агротехнологии получения высоких урожаев для данных условий. Почвы опытного участка характеризуются благоприятными агрофизическими и водными свойствами и низким содержанием гумуса, нитратного азота, подвижного фосфора и содержанием обменного калия от низкого до среднего. Сравнивали 18 сортообразцов батата. Выделенные сортообразцы изучали при ширине междурядий 70 и 90 см со схемой 70×25 и 90×20 см по 1, 2 и 3 растения в гнезде. Для получения рассады сортообразцов батата брали по 40 клубней и высаживали 20–22 февраля в пленочной теплице при температуре 15–18 °C, заделывая их на глубину 3–5 см. Влажность почвы поддерживали на уровне 65–70%. Через 7–10 дней после высадки почки начинают прорастать, а через 43–48 дней формируется рассада высотой 12–15 см, готовая для высадки в поле. Высадка рассады, как и других рассадных культур (томата, перца, баклажана) – по схеме 70×20–25 см во второй-третьей декаде апреля. Уход включал в себя междурядную обработку (культивация), прополку, борьбу с сорняками, подкормку, поливы. Уборка урожая – в конце сентября-начале октября с помощью картофелекопателя. В результате исследований выделились сорта по скороспелости, дружности формирования ростков, ускоренному размножению, продуктивности, компактности клубней в гнезде и с высоким товарным урожаем – Сочакинур, Хар-Бей и Япон. Возделывание этих сортообразцов по схеме 70×25 и 90×20 см способствует получению товарного урожая высокого качества не менее 43–48 т/га. In 2017–2019, studies were conducted on the study of varieties of sweet potatoes on old-irrigated meadow-gray-earth soils of the Zarafshan valley. The purpose of the research is a comprehensive assessment of sweet potato varieties in the conditions of the Zarafshan valley in terms of early maturity, growth, development, intensive reproduction, yield formation, compactness of tubers in the nest, productivity, yield and keeping quality of tubers and the selection of promising ones, as well as the development of methods of agricultural technology for obtaining high yields for given conditions. The soil is characterized by favorable agrophysical and water properties and low content of humus, nitrate nitrogen, mobile phosphorus and a low-average content of exchange potassium. Eighteen sweet potato varieties were compared. The selected variety samples were studied with a row spacing of 70 and 90 cm with a scheme of 70×25 and 90×20 cm for 1, 2 and 3 seedlings in the nest. To obtain seedlings of sweet potato varieties, 40 tubers were taken and planted on February 20–22 in a film greenhouse at a temperature of 15–18 °C, seeding to a depth of 3–5 cm, the soil moisture was maintained at 65–70%. 7–10 days after planting, the buds began to germinate, and after 43–48 days, seedlings were formed with a height of 12–15 cm, which is ready for planting in the field. Planting seedlings in the field is carried out, as well as other seedlings (tomato, pepper, eggplant) according to the scheme 70x20–25 cm in the second or third decade of April. Growing includes inter-row processing (cultivation), weeding, weed control, top dressing, watering. Harvesting in late September, early October with a potato digger. As a result of the research, varieties were identified in terms of early maturity, sprout formation, accelerated reproduction, productivity, compactness of tubers in the nest and ensuring a high marketable yield – Sochakinur, Xar-Bey, and Japon. The cultivation of these varieties according to the scheme 70×25 and 90×20 cm contributes to the production of a commodity crop at 43–48 t/ha with good qualities.
