Resistance to most sugarcane diseases in modern interspecific hybrids (Saccharum spp.) is often intuitively attributed to resistance alleles that may have been derived from the wild species S. spontaneum. This intuitive breeders' opinion stems from the fact that, for many diseases, the noble species S. officinarum is often relatively susceptible, while the wild species shows good levels of resistance, and is therefore thought to be the main species that have provided improved resistance.
The Sugarcane Research Institute of Cuba (INICA) provides a breeding program to develop new cultivars for the industry. This implies that an extensive volume of data is handled annually from a population of clones and cultivars in different stages of selection.
The sugarcane sector in the Cauca River Valley, Colombia, is strongly influenced by high soil variability and the presence of El Niño-La Niña climatic phenomena. Due to this, it is necessary to establish crop management strategies that ensure stable production.
The Sugarcane Breeding Program (SCBP) of Estación Experimental Agroindustrial Obispo Colombres (EEAOC) focuses on the development of cultivars with broad adaptation to different environments in the sugarcane-growing area of Tucumán, Argentina. Different biometric approaches, both parametric and non-parametric, allow for a combined analysis of the performance and stability of a cultivar.
