A calibration curve for predicting sucrose content of sugarcane using NIR spectroscopy directly in the field
Last Updated: junio 11, 2025The development of new sugarcane cultivars requires a systematic selection process to identify genotypes with desirable traits, such as tillering, disease resistance, sucrose content, and high yield. Near-Infrared (NIR) spectroscopy has been integrated into breeding programs to enhance the accuracy of sugar content measurements.
A pathway to molecular sugarcane breeding: implementing genetic associations and genomic prediction
Last Updated: junio 11, 2025Sugarcane is a major crop used to produce sugar, ethanol, and energy. Given its importance, plant-breeding programs worldwide focus on selecting varieties with higher biomass and sucrose yield, as well as resistance to major diseases. Selection is generally based on phenotypic information.
A selection index based on non-sugar compounds of sugarcane juice
Last Updated: junio 11, 2025Sugarcane juice is composed of sugars, water, and different soluble and insoluble substances known as non-sugar compounds. Both sugar and non-sugar compounds are crucial in the factory because they are responsible for adverse effects on the quality and recovery of sucrose.
Accuracy of genomic selection in populations of the EEAOC sugarcane breeding program
Last Updated: junio 11, 2025Genomic selection (GS) is a promising breeding tool for improving the efficiency of complex trait breeding. The prediction accuracy of genomic breeding values was assessed across populations at different stages of the Sugarcane Breeding Program at the Estación Experimental Agroindustrial Obispo Colombres (SCBP-EEAOC).
Association between vegetative indices evaluated in a sugarcane breeding population
Last Updated: junio 11, 2025Sugarcane breeders are always looking for new variables to improve the efficiency of identifying superior genotypes. Multispectral sensors onboard unmanned aerial vehicles (UAVs) can provide a non-destructive and faster phenotyping strategy where the information can be summarized as vegetative indices.
Automation of artificial photoperiod in the north of Argentina
Last Updated: junio 11, 2025The Sugarcane Breeding Program at Chacra Experimental Agrícola Santa Rosa conducts crosses using artificial flower induction. To enhance this process, we developed a new automated photoperiod control system. This system utilizes microcontrollers that send ON/OFF signals to light fixtures in the photoperiod chambers while receiving real-time sensor data.
Brix and stalk number associated with sugarcane productivity in different edaphoclimatic conditions in Brazil
Last Updated: junio 11, 2025Brix and stalk numbers associated with sugarcane productivity (Brix and number of stalks) were determined under different soil and climate conditions in Brazil using material from the early stages of the selection program of the Agronomic Institute of Campinas - IAC.
Evaluation of brown and orange rust resistance genes in sugarcane through molecular markers
Last Updated: junio 11, 2025Molecular markers associated with resistance genes, such as Bru1 (brown rust) and G1 (orange rust), hold significant potential for predicting resistant genotypes during the selection phases of breeding programs. We aimed to correlate the phenotypic response with the genotypic profiles of Bru1 and G1 markers in a panel of 300 sugarcane accessions, which constitute the Brazilian Panel of Sugarcane Genotypes (BPSG). Among the evaluated accessions, 60.3% (181) exhibited field resistance to brown rust, of which 70.7% (128) carried the Bru1 gene.
Evaluation of freeze-damaged indicators in ‘TUC’ sugarcane varieties in Tucumán, Argentina
Last Updated: junio 11, 2025In Tucumán, Argentina’s primary sugarcane-producing province, frost events frequently affect optimal crop development, and sugar recovery during industrial processing. The entire sugarcane production area is prone to frost. Therefore, characterizing the TUC varieties (developed by the Sugarcane Breeding Program of the Estación Experimental Agroindustrial Obispo Colombres (SCBP-EEAOC)), in relation to frost-induced deterioration is crucial for optimizing cultivar management strategies.
Genetic control of sucrose content among unselected progeny populations
Last Updated: junio 11, 2025Genetic control references additive and non-additive genetic effects in plants and is used to determine breeding strategy. The objectives were to determine additive and non-additive genetic control for sucrose content and evaluate implications on sugarcane breeding.
