Preliminary Evaluation of 21 Certified Virus-free Citrus Clones

Abstract

Twenty-one clonal varieties of citrus were evaluated at the Gurabo Substation fruit yield and characters. Average fruit production during the 3-year study of Pineapple and Temple clones and the majority of the Valencia clones was higher than the ones reported from commercial orchards in Puerto Rico. The clones of Pineapple, Temple and Orlando Tangelo have the most seedy fruits with 18, 13 and 13 seeds per fruit, respectively. For most of the clonal varieties, seed content was lower and acceptable. Lue Gin Gong and most of the Valencia clones produced the highest percentages of juice per fruit.
