Goals / Objectives
- Create hybrid rootstocks which combine germplasm from parental material with good rootstock traits and huanglongbing (HLB) tolerance, propagate the most promising of these hybrids, and establish replicated field trials with commercial scions.
- Collect field performance data from early-stage replicated rootstock field trials and release new rootstock cultivars as justified by superior performance in multiyear field trials.
Methods (unparsed)
Make crosses with new parental combinations. Complete propagation of trees for new trials. Plant new replicated field trials with new rootstocks. Tree size and health measurements. Fruit yield and fruit quality measurements. Polymerase chain reaction (PCR) evaluations of Candidatus Liberibacter asiaticus (CLas) infection.
