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).
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.
Genetic diversity in EEAOC’s germplasm bank and assessment of a core collection
Last Updated: junio 11, 2025Understanding the genetic diversity and population structure of sugarcane germplasm banks provides valuable information to produce progenies with maximum variability. To this end, 350 accessions of the EEAOC´s germplasm bank were genotyped at 74,969 biallelic SNP loci using DArT-seq technology.
Genome size variation in complex sugarcane parental genotypes in United States sugarcane breeding
Last Updated: junio 11, 2025Modern sugarcane (Saccharum spp.) (`~12x) has a very complex genetic blueprint. The genome size (2C DNA) of 61 Saccharum parental genotypes was estimated using flow cytometry, and whether the 2C value is associated with the clone’s fertility traits was tested.
Genotypic values and genetic gains in sugarcane varieties for sandy soils in Florida, USA
Last Updated: junio 11, 2025A sugarcane breeding program for sandy soils was started in Florida in 2011. After 10 years, genotypic values and the trend of genetic gains for cane yield (CY) and commercial recoverable sucrose (CRS) were evaluated. Fifty-six test varieties and three check cultivars planted in three or four sand locations were evaluated based on Best Linear Unbiased Prediction (BLUP) during plant cane and two ratoon crops.
Partitioning sugarcane variance components for sucrose yield in Stage I populations
Last Updated: junio 11, 2025In Colombia, sugarcane for sugar production is located in the Cauca River Valley and Meta regions and is planted on about 240.000 ha with more than 3.800 farms and 15 mills and has the highest yield of cane per hectare (TCH) per year in the world. Although TCH production seems to be high, Cenicaña’s breeders have only been able to achieve low pol % due to the genetic makeup of the trait, the effects of the environment (Niño-Niña), and the agro-industrial practices involved in farming in the area.
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 11, 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.
