Summary: Characterisation of phenotypic and genetic diversity of two cultivated buckwheat species, Fagopyrum esculentum and Fagopyrum tataricum, was conducted using 37 agro-morphological traits and 24 SSR markers. Variations in most traits were observed in both species, with seeds and flowering contributing to the differentiation. Phenoclustering analysis revealed no clear geographic clustering. Polymorphic SSR markers showed high informativeness and genetic diversity, with significant differences between species. The weak genetic structure suggested frequent seed exchange and extensive cultivation and selection. Marker-trait associations were identified, providing insights for genomics-based breeding programs and germplasm management.

Summary: This study used microsatellite (SSR) markers to investigate the genetic status of 12 Bulgarian autochthonous sheep breeds. A total of 600 individuals from 50 flocks were analyzed, and 228 alleles were found. The results showed low differentiation between the breeds, with two breeds being the most distinct and the remaining breeds showing poor breed differentiation. Proper management strategies and breeding policies are needed to avoid intermixing of breeds and preserve breed purity.

This study investigated the genetic diversity and relationships of TIPs from three regions of Thailand using microsatellite markers. The TIPs showed high genetic diversity and divergence from European and Chinese breeds. The study highlights the urgent need for a breeding program to conserve these indigenous pig populations.

Summary: Brazil is one of the largest grain producing countries in the world and one of the largest importers of soluble fertilizers. This study evaluated the efficiency of a mixture of poultry litter and soil remineralizer as an alternative source of nutrients for maize fertilization. The results showed that larger doses of soil remineralizer improved soil attributes and plant growth, suggesting that this mixture could be a high-quality, low-cost, and sustainable fertilization option.

Summary: This study examined the effect of A. brasilense on Brachiaria seedlings, rhizosphere, and soil. The results showed that inoculation with A. brasilense increased the aboveground biomass of Brachiaria plants but did not affect root biomass. Soil texture was found to be a crucial factor in shaping rhizosphere communities.

Summary: Marker-assisted recurrent selection was used to pyramid resistance gene alleles against coffee leaf rust and coffee berry diseases in Coffea arabica. 144 genotypes from 12 hybrid populations were evaluated, and molecular data were used for cross-certification, diversity study, and resistance allele marker-assisted selection. The results showed that the strategy of pyramiding resistance genes using marker-assisted selection was efficient in selecting superior coffee hybrids and could be used as a source of resistance in various crosses.

Summary: In Brazil, mining companies generate a significant amount of residue from rock processing, including basalt rock powder (BRP). BRP has potential as an alternative fertilizer and holds environmental and economic importance. This study investigated the effects of BRP and limestone on soil fertility and the growth of soybean and corn plants. The results showed that BRP and limestone application led to increased levels of calcium, magnesium, phosphorus, and pH in the soil, as well as enhanced shoot dry matter of soybean and corn plants. However, potassium levels in the soil decreased due to plant uptake, with BRP treatments showing lower reduction compared to limestone treatments.

Summary: The objective of this study was to determine the duration of phenological stages, growth development, yield, and cone quality of hop cultivars under artificial light in a subtropical climate. The study was conducted in Brazil during 2021 and 2022. Different cultivars were used in the experiment, and various measurements were recorded, including plant height, fresh mass, number of lateral branches, cone characteristics, and chemical components. The results showed that the early-maturing cultivars had higher yields and better cone quality. Yakima Gold cultivar exhibited positive correlations with chemical components of the cones.

Summary: Production costs in Brazilian agriculture have increased due to the rising prices of imported soluble fertilizers. To reduce import dependence, low-cost indigenous nutrient sources such as basalt rock powder (BRP) have been tested. The study found that applying BRP increased dry mass production, improved soil fertility, and increased leaf phosphorus content, while limestone only affected soil pH and calcium content.

Summary: This study aims to evaluate and differentiate crambe genotypes in terms of water deficit tolerance using morpho-agronomic and physiological traits. The experiment was conducted in a greenhouse, employing a randomized complete block design. The results showed that water deficit did not cause severe physiological limitations to the plants. Plant height, total dry mass, and grain yield were the traits that exhibited the highest potential for genetic gains through selection. The cultivar FMS Brilhante and inbred lines FMS CR 1326 and FMS CR 1106 showed the most favorable traits for water deficit tolerance.

Summary: This study evaluated the physiological potential of Urochloa decumbens seeds using FT-NIR and ILASTIK analysis techniques. The FT-NIR analysis successfully established a high-efficiency classification model using pre-processing methods, while ILASTIK analysis was able to effectively classify seeds after only 7 days of germination. Both of these non-destructive and fast analysis methods show great potential for quality control of U. decumbens seed lots.
