Sprengel, P. erosus (L.) Urban, and P. ahipa (Wedd.). Its storage root dry matter content (SRDM) is usually low, although genotypes with a high SRDM have been identified ('Chuin' accessions). Flowers are often removed through flower pruning (FP) to increase storage root fresh matter yield (SRFY). The main objectives of this study were to investigate the potential for use in Benin (West Africa), to estimate the effect of FP, and to test whether roots could be processed into gari. In total, 34 accessions were tested at one drought-stress and one irrigated location. Means and genetic variance components were estimated for 33 agronomic traits. Without FP, the SRFYs of P. tuberosus, P. erosus, and P. ahipa were 13.9, 23.4, and 12.4 t ha(-1), respectively, and the seed yields were 2.2, 5.2, and 2.1 t ha(-1), respectively. The FP caused SRFY to increase by 48, 91, and 61% in P. tuberosu, P. erosus, and P. ahipa, respectively. The storage root dry matter yield (SRDY) of P. erosus was only slightly higher (-8.5 t ha(-1)) than that of the Chuin accessions (-8.0 t ha(-1)). Under drought, the SRDY was least affected in P. erosus. Early-maturing P. ahipa accessions were identified. All species could be used to make gari, which contained, on average, 5.5% protein, 58.5% starch, and 23.8% total dietary fiber. The crop has the potential for use in West Africa and has a large genetic variation for genetic improvement."],["dc.identifier.doi","10.2135/cropsci2006.03.0153"],["dc.identifier.isi","000250074800020"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/50555"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Crop Science Soc Amer"],["dc.relation.issn","0011-183X"],["dc.title","Evaluation of the storage root-forming legume yam bean (Pachyrhizus spp.) under west African conditions"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Worldwide interest in potato as a valuable food security crop is increasing, because it is not globally traded, the prices are determined by local production costs and due to its beneficial impact on human nutrition. In the present review, organic and conventional potato productions were assessed by means of key indicators for sustainability. These indicators were fertility management and crop protection, yield level, tuber quality and environmental impact. The evaluation of several studies shows that each system has advantages and disadvantages. None of the production systems is per se more sustainable than the other. Each of them has potential for improvement of the system performance. In organic production, for example, by establishment of improved fertilization (e.g., application of more N-efficient base organic fertilizers) and crop management strategies (e.g., pre-sprouting of seed tubers, bio-based fungicides), in conventional farming by implementation of more target-oriented fertilization and pesticide spraying schedules.

Moreover, the mycotoxin concentration of the grains was evaluated to characterize the infection degree. Inoculation of naked barley with Fusarium led to grain deoxynivalenol concentrations of up to 1.2 mg/kg. The carbon and nitrogen grain concentrations were not significantly changed after fungal infection, but differed between growing locations. Eleven proteins related to fungal infection were detected as were three proteins with effects based on growing location.

For this objective, 60 cultivars deriving from very diverse breeding programs 1880–2015 were evaluated in 2015, and a subset of 20 cultivars was selected for further evaluation in 2016. The diversity of instrumentally determined traits, especially for VOCs concentration and sensory properties (fruit firmness, juiciness, skin firmness, sweetness, sourness, aroma, and acceptability), was investigated at two harvest dates. The evaluation of the cultivars exhibited a wide range of variation for all studied traits, with the exception of a few VOCs. Cultivar had the most important effect on all instrumentally determined traits, while the influence of cultivar × harvest date × year interaction was significant for 17 VOCs, but not for total soluble solid (TSS) and titratable acidity (TA). The VOCs with the highest proportion (>8%) were hexanal, 6-methyl-5-heptene-2-one, 2-isobutylthiazole, and (E)-2-hexenal, which were identified in all cultivars. Twelve VOCs significantly correlated with one or more sensory attributes and these VOCs also allowed differentiation of the fruit type. Among these VOCs, phenylethyl alcohol and benzyl alcohol positively correlated with acceptability in the cocktail cultivars, whereas 2-isobuthylthiazole and 6-methyl-5-hepten-2-ol negatively correlated with acceptability in the salad cultivars. As a result of this study, organic breeders are recommended to use cultivars from a wide range of breeding programs to improve important quality and agronomic traits. As examples, salad tomatoes “Campari F1”, “Green Zebra”, and “Auriga”, as well as cocktail tomatoes “Supersweet 100 F1”, “Sakura F1”, and “Black Cherry” showed higher scores for the sensory attributes aroma and acceptability under organic low-input growing conditions.
