The major contribution of resistance to orange rust and yellow leaf in modern sugarcane hybrids comes from Saccharum spontaneum as evidenced by genome-wide association studies
Last Updated: junio 19, 2025Resistance 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.
Transgenic sugarcane expressing insecticidal proteins increases resistance to Diatraea saccharalis
Last Updated: junio 19, 2025The sugarcane borer Diatraea saccharalis is a major pest of sugarcane (Saccharum hybrids) in the Americas. The insect is partially controlled by cultural, biological, and chemical methods, but still causes significant economic losses.
Unveiling sugarcane resistance to Aeneolamia varia: implications for pest management
Last Updated: julio 6, 2025Since its detection in 2007, the spittlebug Aeneolamia varia has increasingly threatened sugarcane production in the Cauca River Valley in Colombia. By 2021, 84% of the sugarcane area (241,169 ha) grew varieties susceptible to this pest, highlighting the need for genetic resistance studies. This study aimed to identify sugarcane genotypes with contrasting levels of damage (higher and lower than a control) to investigate potential resistance mechanisms.
Updating SASEL software: intelligent data management to support the Cuban sugarcane breeding program
Last Updated: junio 19, 2025The 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.
Using the Axiom SNP array for comparative mapping across four Australian sugarcane varieties
Last Updated: junio 19, 2025Comparative mapping in sugarcane has had limited application due to initially markers such as AFLPs being used to generate maps for the large genome with no sequence information attached.
Varietal diversity in sugarcane cultivation: a key factor in productivity sustainability
Last Updated: junio 19, 2025The 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.
Vegetative indices in early and late flowering sugarcane genotypes assessed by high-throughput phenotyping
Last Updated: julio 6, 2025High-throughput phenotyping (HTP) using unmanned aerial vehicles is a valuable approach to accelerate the collection of phenotypic data in large field trials. Our primary objective was to investigate the differences between early (EF) and late (LF) sugarcane flowering time groups in an association mapping panel based on vegetation indices (VI), such as canopy cover (CC), excess greenness (EXG), plant volume and plant height obtained from RGB images, and stalk number by manual counting.
Vitropathogen control in EEAOC’s sugarcane micropropagation scheme
Last Updated: junio 19, 2025A significant problem in in vitro culture is endogenous contamination (viruses, viroids, bacteria, fungi or yeasts inside cells, in intercellular spaces or vascular bundles) since they cannot be eliminated by chemical disinfection before micropropagation.
Yield indicators affected by ratoon stunting disease in sugarcane varieties planted in northern Argentina
Last Updated: junio 19, 2025This field study assessed the impact of sugarcane ratoon stunting disease (RSD) infection on yield indicators of commercial varieties in Jujuy and Salta. Yield indicators were measured in randomly selected stems sampled from paired plots from a field trial previously planted with clean and RSD-infected seed cane of different disease intensities
Yield performance and environmental adaptability of cultivar TUC 03-12 analyzed by two statistical approaches
Last Updated: junio 17, 2025The 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.
