Summary

Since humans started the processes of plants selection and improvement until the present day, the selection of superior individuals based on their morphological and phenotypic characters has allowed the development of a large number of hybrids and varieties with agronomic characteristics of great interest, including resistance to biotic and abiotic factors that limit crop production. Currently, conventional plant breeding programs have tools that, in combination with molecular methods, have reduced time, saved resources and achieved pyrimidization of characteristics in new crops. This seminar will address how in Cenicafé the combination of conventional breeding techniques and marker-assisted selection (MAS) has allowed Colombian coffee growers to have varieties resistant to potential and limiting diseases, which were developed in the absence of pathogens. Additionally, research on how marker-assisted selection has allowed to advance populations with new rust resistance genes, which have not yet been used in commercial varieties in the country are presented.
