Comparison of Rohde Red and common valencia juice color and maturity

Robert E. Rouse, Renee M. Goodrich


The 'Rohde Red Valencia' orange cultivar (Citrus sinensis L. Osbeck) appeared as a limb sport in a Highlands county grove in 1955. Fruit is typical to many old-line 'Valencia' oranges in size and production, but develops a deeper juice color. Color scores have ranged from 39 to above 40. 'Rohde Valencia' selections have shown some tendency to be unstable exhibiting non-uniform color among fruit, low fruit yield, irregular bearing, and non-true-to-type leaf characteristics. Previous reports have shown clone RRV-472-11-43 (STG-19- 2)-X-E to be superior to other 'Rohde Red Valencia' clones, and is the only selection available from the Florida citrus budwood program. Fruit quality measurements from fruit in the Budwood Foundation Block in Immokalee show color development in 'Rohde Red Valencia' begins to exceed common 'Valencia' about December and continues to enhance through maturity. 'Rohde Red Valencia' has lower acid, lower Brix, higher ratio, and higher color than common 'Valencia'. The purpose of this report is to show when color development occurs in 'Rohde Red Valencia' during the development period in relation to other fruit maturity characteristics.
