Location: Sugarcane Field Station2013 Annual Report
1a. Objectives (from AD-416):
The development of new disease-resistant high-yielding sugarcane cultivars specifically adapted for Florida.
1b. Approach (from AD-416):
Cross superior sugarcane to produce "true-seed", germinate in greenhouse and transplant individual seedlings (clones) to field. Evaluate and select superior high-yielding disease-resistant sugarcane clones in multi-year trials in a tri-party cooperative program on ARS and on grower farm locations and to vegetatively increase seedcane of the seeded clones.
3. Progress Report:
This research relates to inhouse objective 2: Develop better agronomic practices for the Florida sugarcane industry. The Florida sugarcane development program at Canal Point requires at least 9 years to develop a commercial cultivar from the time a cross is made. The most recent challenge facing Florida sugarcane growers is the introduction of orange rust. True seeds, developed from crosses at Canal Point, Florida, were sent to the ARS cultivar development program in Louisiana. In the 2012/2013 crossing season, it is estimated that 206,703 seeds from 315 crosses were sent to Louisiana; and 492,164 seeds from 1,188 crosses remained in Florida. Cultivars developed by ARS occupied more than 86% of the sugarcane acreage in Florida in 2012. This breeding and selection program at Canal Point develops sugarcane cultivars for sand and organic (muck) soils in Florida. Improvements are needed in cultivar selection for sand soils. In 2013, for the third consecutive year, all stages of the selection program were planted on sand soils, beginning with the seedling stage. In addition, all stages of the selection program were conducted on muck soils. Two recently released varieties, CP 00-1101 and CP 01-1372 are being expanded rapidly and now are grown on more than 16% of the sugarcane acreage in Florida. In addition, in 2013, there was one new variety released, CP 06-2400. It is expected to yield well on muck soils. CP 06-2400 was resistant to brown rust and orange rust.
