Germplasm and 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.
Impact of sugarcane smut in the EEAOC sugarcane breeding selection process during the last 10 years
Last Updated: junio 11, 2025The focus of the Sugarcane Breeding Program of the Estación Experimental Agroindustrial Obispo Colombres (SCBP-EEAOC) is to develop new TUC varieties with high cane yield and sucrose content, early maturity and good phytosanitary behavior, among other industrial and agronomic aspects. From 2020/2021 season, sugarcane smut (Sporisorium scitamineum) increased in prevalence in Tucumán, Argentina, becoming one of the main sugarcane diseases in the region.
In vitro mutagenesis for enhancing genetic variability in Argentinian sugarcane cultivarsIn vitro mutagenesis for enhancing genetic variability in Argentinian sugarcane cultivars
Last Updated: junio 11, 2025The complexity of the sugarcane genome, the narrow genetic base of subtropical germplasm, and the extended breeding and selection cycle pose significant challenges to conventional breeding methods. In vitro mutagenesis offers an alternative approach to generating genetic variability by harnessing both somaclonal variation and induced mutations.
Measuring Brix directly in the sugarcane stalk with a regenerative plant sensor
Last Updated: junio 11, 2025Maximizing the yield potential of sugarcane varieties requires accurate assessment of physiological maturity, as under-aged or over-aged cane can lead to reduced sugar yield, poor juice quality, and difficulties in sugar recovery.
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.
Retrospective analysis of progenitors in the sugarcane breeding program of Estación Experimental Agroindustrial Obispo Colombres from 1998 to 2020
Last Updated: junio 11, 2025Each year the Sugarcane Breeding Program of Estación Experimental Agroindustrial Obispo Colombres (SCBP-EEAOC) in Tucumán, Argentina, selects the progenitors to be used in biparental crossings. The present study aimed to analyze the parents chosen between 1998 and 2020 (23 seasons) in the SCBP-EEAOC based on their level of exploration and the number of selected individuals of their progeny in early selection stages.
Scaling of temporary immersion systems to produce clean seed cane for northern Argentina
Last Updated: junio 11, 2025Tissue culture allows for the rapid propagation of sugarcane planting material of high phytosanitary and genetic quality. This paper describes the modernization of the tissue culture facilities at the Santa Rosa Agricultural Experimental Farm.
The crucial role of the EEAOC breeding program: varietal diversification in the sugarcane area of Tucumán, Argentina in the last 10 years
Last Updated: junio 11, 2025The Sugarcane Breeding Program of the Estación Experimental Agroindustrial Obispo Colombres (SCBP-EEAOC) is focused on the development of TUC varieties with high yield of cane and sucrose, early maturation, and resistance to the main diseases prevalent in Tucumán, Argentina.
