2009 Annual Report
1a.Objectives (from AD-416)
To select and cross superior sugarcane parents, produce true-seed and test new sugarcane clones to identify and release higher-yielding disease-resistant sugarcane cultivars.
1b.Approach (from AD-416)
ARS and the Cooperator will produce and exchange true-seed (commonly called Fuzz), superior experimental lines, and/or new varieties (Material) for use in their respective breeding programs and/or for testing and evaluation as parental clones and/or as commercial cultivars.
This project relates to inhouse objective 3: Identify alleles or genes that can be used in molecular marker-assisted selection to complement the conventional approach of sugarcane cultivar development.
In the 2008/2009 crossing season we sent 16,158 seeds from 243 crosses using 569 female tassels to the breeding program at Texas A&M University. Of these 243 crosses, seeds from 192 crosses using 460 female tassels were made and shared between the ARS Florida program and the Texas A&M breeding program.
Progress was monitored during one week that support personnel from Texas A&M spent at USDA-ARS, Canal Point, Florida, making crosses for Texas. In addition, there were several emails and phone calls between scientists at College Station and Canal Point to decide on parent genotypes to be used for Texas and to identify genotypes not currently at Canal Point that needed to be imported.
