Abstract
A new and distinct sweet orange clone ‘OLL-20’ has been developed from an unstable sweet orange selection designated as ‘OLL’, using tissue culture techniques. Undeveloped ovules from fruit of selection ‘OLL’ were cultured in vitro to generate an embryogenic callus, from which multiple independent clones were regenerated via somatic embryogenesis. Regenerated plantlets (somaclones) were grafted to UFR rootstocks and grown in the field for evaluation.
