Title: Assessing Budsports of ´Valencia` Sweet Orange [Citrus senensis (L.) Osbeck] for Desirable Characteristics
Author: D. Kotsias
Abstract:
Three mutant clones of 'Valencia' orange were compared to the standard cultivar.
All selections and
the source cultivar were grafted onto Citrus aurantium L. rootstock and assessed for yield, vigor, fruit
quality and other morphological characteristics for a period of four years.
Two clones (A and B) displayed significant improvements over the standard Valencia cultivar.
Over
4 consecutive years, major characteristics such as yield, fruit morphology and juice quality were found
to be better in clones A and B. Clones A and B gave a greater yield per tree and greater mean fruit weight,
while clone A gave a higher endocarp/pericarp ratio and increased endocarp weight.
Clones A and B
contained more juice per fruit, and higher total soluble solids and vitamin C compared to the standard
'Valencia' clone.
Clone B ripened at the same period as main cultivar, while clone A ripened 30-35 days
later and clone C 30 days earlier
The improved characteristics and altered ripening time of clones A and B warrant propagation of this
plant material and broader testing on a commercial scale.
