Objective: To describe the advances in the sugarcane variety selection program that is carried out by the Campus Córdoba of the College of Postgraduates in Agricultural Sciences located in Amatlán de los Reyes, Veracruz, Mexico.

Design/methodology/approach: For the selection of sugarcane varieties, the methodology developed by the Institute for the Improvement of Sugar Production (IMPA) was used, and for the varietal description, the protocol of the International Union for the Protection of New Varieties of Plants (UPOV) was implemented.

Results: In 2009, the Campus Córdoba started the varietal selection program with more than 6 thousand hybrids from 40 crosses, of which 4422 materials were selected after showing resistance to the sugarcane mosaic virus. From the 4422 materials of the seedling phase, 352 clones were selected and evaluated in the Furrow Phase, selecting 57 varieties for the Plot Phase. Of these 57 varieties, 36 were selected in the Adaptability Test Phase, and 27 in the following Agroindustrial Evaluation Phase. Of these last 27 varieties, estimated yields are greater than 100 t ha-1, with good quality of juices and agronomic characteristics.

Study limitations/implications: The program has faced climate and budget challenges, delaying progress. Currently, the Covid-19 pandemic has drastically affected our research.

Findings/conclusions: This breeding and variety selection program started with 6,000 crosses, of which to date there are 27 in advanced stages of selection, with the possibility of adaptation and good yields for the area of influence of the Campus Córdoba.
