What shapes food value chains? Lessons from aquaculture in Asia por Jespersen, K.S., Kelling, I., Ponte, S., Kruijssen, Froukje

“…We find that the most sophisticated aquaculture operations in Asia are found in value chains led by retailers and branded processors and where the quality of domestic institutional frameworks has facilitated compliance with increasing demands from buyers overseas. Finally, we reflect on the sustainability challenges of aquaculture and provide four broad observations on the governance of food value chains.…”

Focusing basic research for cassava varietal improvement por Iglesias F., Carlos Ariel, Bonierbale, Merideth W., El-Sharkawy, Mabrouk A., Lozano T., José Carlos, Bellotti, Anthony C., Wheatley, Christopher C.

“…It also refers to methodologies for the creation of new genetic diversity, and multi-institutional approach to gene-pool development in cassava. Finally, some of the major challenges and opportunities in basic research to sustain cassava genetic improvement are discussed and a continued and increased emphasis on broad-based breeding programs for cassava in developing countries, combined with the use of biotechnology when appropriate is advocated…”

Dynamics of pasture discharge and its architecture por Gastó, Juan M.

“…Some parameters related to discharge such as grazing intensity and use intensity, as well as ecological cost of the harvest, are included in the study. Finally, the discharge of an annual Mediterranean meadow is described as an example of the process.…”

Estimacion de los parametros geneticos en la yuca por Bueno, A.

“…Other concepts discussed are heritability and its estimation (based on regression or on components of variance) and correlated factors. Finally, the results of different studies carried out to estimate the components of variance in cassava or the heritability in the crop are reviewed, as well as correlated characters. …”

Simulating the evolution of soil solutions in irrigated rice soils in the Sahel por Hammecker, C., Asten, Piet J.A. van, Marlet, S., Maeght, J.L., Poss, R.

“…It was possible to simulate the evaporation of the ponding water, the mixing between groundwater and irrigation water, the lateral drainage (flushing) and the leaching, and finally the management of the crop residues. By performing prospective simulations over 60 cropping cycles it has been shown that soil alkalinization and sodication are not inevitable in these areas especially if the cropping is properly managed. …”

Current strategies of polyploid plant genome sequence assembly por Kyriakidou, M., Tai, H.H., Anglin, Noelle L., Ellis, David, Stromvik, M.V.

“…As genomes of diploid and less heterozygous progenitor species are increasingly available, we discuss the lack of complexity of these currently available reference genomes as they relate to polyploid crops. Finally, we review recent approaches of haplotyping by phasing and the impact of third generation technologies on polyploid plant genome assembly.…”

Sunpheno : a deep neural network for phenological classification of sunflower images por Bengoa Luoni, Sofía Ailin, Ricci, Riccardo, Corzo, Melanie Anahi, Hoxha, Genc, Melgani, Farid, Fernandez, Paula Del Carmen

“…From the analysis, we found that the method based on the pre-trained network resnet50 outperformed the other methods, both in terms of accuracy and velocity. Finally, the model generated, Sunpheno, was used to evaluate the phenological stages of two contrasting lines, B481_6 and R453, during senescence. …”

Genomic-based multiple-trait evaluation in Eucalyptus grandis using dominant DArT markers por Cappa, Eduardo Pablo, El-Kassaby, Yousry A., Muñoz, Facundo, Garcia, Martin Nahuel, Villalba, Pamela Victoria, Klapste, Jaroslav, Marcucci Poltri, Susana Noemi

“…Furthermore, the multiple-trait combined approach was proven to be superior to the single-trait combined approach in predicting breeding values, in particular for low-heritability traits. Finally, our results advocate the use of the combined approach in forest tree progeny testing trials, specifically when a multiple-trait individual-tree mixed model is considered.…”

Arthropod Pest Management in Organic Vegetable Greenhouses por Weintraub, Phyllis G., Recht, Eitan, Mondaca, Lilach Lily, Harari, Ally R., Diaz, Beatriz Maria, Bennison, Jude

“…Our discussion covers greenhouse structure; the first line of defense, regulatory, and phytosanitary measures; various management methods; and finally specific management of primary pest groups, mites, thrips, hemipterans (aphids, mealybugs, and whiteflies), and small Lepidoptera.…”

Development of a pododermatitis score in breeding does using clustering methods por Olivas, Irene, Torres, Antonio G., Villagrá, Arantxa

“…These clusters were later comprehensively described in terms of pododermatitis severity. Finally, attending to cluster description, a five-level score was defined and this scale resulted in a practical and objective way to assess pododermatitis in rabbit does. …”

Development of models to predict product deposition from coverage obtained on artificial collectors and their practical applications por Garcerá, Cruz, Moltó, Enrique, Chueca, Patricia

“…The best fitting model was selected from among those that had highest coefficients of determination (R-2) and lowest estimation error (RMSEP), and at the same time resulted in a normal distribution of residuals. Finally, coverage on pieces of PVC sheets was related with coverage obtained on WSP by different equations depending on the product being applied. …”

Mejora genética del albaricoquero en el Instituto Valenciano de Investigaciones Agrarias por Badenes, María L., Martínez-Calvo, José

“…Este descenso ha sido especialmente importante en la Comunidad Valenciana, que ha pasado de producir más de 45.000 t a finales de los 90 (segundo lugar nacional) a tan sólo 6.900 t (tercer lugar detrás de Murcia y Aragón) (MAPA, 2012). …”
