Research Project: Breeding Improved High-yielding Disease Resistant Sugarcane Cultivars

Location: Sugarcane Field Station

Project Number: 6030-21000-006-33-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Feb 1, 2018
End Date: Jan 31, 2023

Objective:
1. Produce sufficient and high quality true seed of recommended crosses at Canal Point to supply the Florida cooperative sugarcane breeding programs. 2. Select, develop and release high-yielding sugarcane cultivars with disease resistance. 3. Evaluate varieties under different sugarcane production systems in use in Florida. 4. Develop marker assisted selection for hard to select traits. 5. Develop and institute new disease screening methods for important sugarcane pathogens.

Approach:
Make crosses with basic species of Saccharum and related genera. All known techniques will be used to synchronize flowering to increase the probability of making desirable crosses, hybrids will be crossed and backcrossed under unconventional systems of breeding in an effort to increase the genetic contribution of the exotic parents in commercial cultivars. The influence of environmental conditions, stalk preservation techniques of both male and female and pollen loading (ratio of male: female tassels) will be evaluated. Screening methods for important diseases will be refined and incorporated in the Canal Point (CP) sugarcane cultivar development programs for organic and mineral soils. Variety yield trials will be assessed under various production methods, including tolerance to shallow muck soils and high water tables.
