Research Project: Evaluation of Cp Cultivars for Yield Parameters and Disease Susceptibility in Nicaragua

Location: Sugarcane Production Research

2012 Annual Report


1a.Objectives (from AD-416):
Develop sugarcane clones with high-yielding disease-resistance potential for evaluation of sugar production.


1b.Approach (from AD-416):
Sugarcane seedlings will be produced from high-yielding disease-resistant parental clones with wide adaptation. Superior clones with high vigor, growth and freedom from diseases will be selected and established in yield trials to identify superior clones.


3.Progress Report:

Fifty eight CP-clones were shipped to Nicaragua Sugar Estates Limited for yield and disease evaluation. In plant crop trials, two CP-Sugarcane clones, CPCL 02-7478 and CPCL 00-1095 yielded 20.2 and 24.4 metric tons of sugar per ha, respectively, compared to their commercial checks of CP 73-1547 and CP 72-2086 at 20.8 and 19.9, respectively in Nicaragua. In second ratoon trials, two clones CP 02-2180 and CP 99-1944 that yielded 24.1 and 17.3 metric tons of sugar per hectare, compared to checks, CP 72-2086 and CP 73-1547 that yielded 20.3 and 19.4. These clones may offer commercial alternatives in Nicaragua.
