Strawberries are produced in tropical regions using imported cultivars adapted to temperate and subtropical climates. These cultivars, under tropical conditions, produce below their genetic potential. Through multivariate analyses, the objective was to evaluate and select short-day strawberry genotypes based on intraspecific crosses, product characteristics, and fruit quality.

- - The study investigates the biocontrol potential of a bacterial strain, B.BV10, through three methods: testing its antifungal properties in the lab, evaluating its effectiveness on strawberry plants in a greenhouse, and analyzing its genome for relevant genetic features regarding its activity.
- - Results showed that B.BV10 effectively inhibited the growth of various harmful fungi and significantly reduced gray mold on strawberry plants while increasing fruit biomass.
- - Genome analysis of B.BV10 revealed it has nearly 3.9 million base pairs, with genes linked to antifungal compounds, biofilm formation, and root colonization, providing insights that could help in developing this strain for agricultural applications in the future.
Tomato plants are highly susceptible to pests. Among the control methods, genetic improvement with introgression of resistance genes from wild accessions into commercial tomato lines is the best alternative for an integrated pest management (IPM). Thus, the objective of this study was to select tomato genotypes in advanced populations (FBC), with higher levels of acylsugar content, greater recurrent parent genome recovery, and resistance to and inherited from .
View Article and Find Full Text PDFMethods of multivariate analysis is a powerful approach to assist the initial stages of crops genetic improvement, particularly, because it allows many traits to be evaluated simultaneously. In this study, heat-tolerant genotypes have been selected by analyzing phenotypic diversity, direct and indirect relationships among traits were identified, and four selection indices compared. Diversity was estimated using K-means clustering with the number of clusters determined by the Elbow method, and the relationship among traits was quantified by path analysis.

- - The study examined how potassium bicarbonate (PB), sodium silicate (SSi), and calcium chelate (CCh) solutions boost resistance against gray mold disease in table grapes by measuring changes in certain enzymes and phenolic compounds.
- - Results showed that these treatments reduced gray mold incidence by 43% (PB), 50% (SSi), and 41% (CCh), with SSi showing the greatest increase in superoxide dismutase (SOD) activity and ascorbate peroxidase (APX) significantly higher in SSi-treated grapes.
- - Calcium chelate (CCh) was the most effective in enhancing total phenolic and flavonoid contents, suggesting that these salt solutions may serve
