“…The development of this field is due to biotechnology (manipulation of single-cell cultures or organized tissues), which provides the basic substrate for the practical use of genetic engineering for potato breeding [ 112 ]. Genetic transformation is a process where numerous identical clones of the R gene are transferred to another bacterium called Agrobacterium tumefaciens .…”

Cultivated potato (Solanum tuberosum) is a major crop worldwide. It occupies the second place after cereals (corn, rice, and wheat). This important crop is threatened by the Oomycete Phytophthora infestans, the agent of late blight disease. This pathogen was first encountered during the Irish famine during the 1840s and is a reemerging threat to potatoes. It is mainly controlled chemically by using fungicides, but due to health and environmental concerns, the best alternative is resistance. When there is no disease, no treatment is required. In this study, we present a summary of the ongoing efforts concerning resistance breeding of potato against this devastating pathogen, P. infestans. This work begins with the search for and selection of resistance genes, whether they are from within or from outside the species. The genetic methods developed to date for gene mining, such as effectoromics and GWAS, provide researchers with the ability to identify genes of interest more efficiently. Once identified, these genes are cloned using molecular markers (MAS or QRL) and can then be introduced into different cultivars using somatic hybridization or recombinant DNA technology. More innovative technologies have been developed lately, such as gene editing using the CRISPR system or gene silencing, by exploiting iRNA strategies that have emerged as promising tools for managing Phytophthora infestans, which can be employed. Also, gene pyramiding or gene stacking, which involves the accumulation of two or more R genes on the same individual plant, is an innovative method that has yielded many promising results. All these advances related to the development of molecular techniques for obtaining new potato cultivars resistant to P. infestans can contribute not only to reducing losses in agriculture but especially to ensuring food security and safety.

Chemical control in agriculture includes the use of chemical agents whose concentrations in the harvest products decrease over time. We analyze mathematically the decrease of pesticide residues in potato tubers, and estimate the involved parameters to predict the evolution of pesticide residual after the last spraying. First, we propose and solve a fuzzy initial value problem (FIVP) associated with a fuzzy differential equations system modeling the pesticide concentration in potato tubers. Second, we apply our model in a real situation, where the evolution of the concentration of chemicals is required, by considering two approaches. In the first one, based on a small set of field data, we use a polynomial regression (LOESS) to input new data and estimate the parameters involved in the FIVP and thus, we determinate the evolution of the concentration of the thiamethoxam, a pesticide used on potato crops. In the second approach, we design a Takagi-Sugeno-Kang model to approximate the degradation of thiamethoxam concentration, by defining a set of fuzzy inference rules based on the data provided by LOESS regression. These two approaches show a similar and good behavior, even having few fuzzy data. Our analysis can be applied in a large class of dynamical systems.
