Abstract

‘BB14-321NA-1’ is the first known genotype selected in a low-chill temperate environment of Central Chile and tested also in the tropical environment of Peru. ‘BB14-321NA-1’ is a high-yielding early season variety that can break buds and produce fruit with very low chill or no-chill since it does not develop endo-dormancy. The fruit of ‘BB14-321NA-1’ is very large with medium blue color, high bloom and excellent fruit appearance. Fruit is firm and has juicy texture. The eating quality of ‘BB14-321NA-1’ is very good, and ‘BB14-321NA-1’ appears to have the option of jumbo early fruit for early spring production in many places of the world. It can be cultivated in soil and soilless production systems.

Description

Latin name: Vaccinium corymbosum.
Common name: Blueberry.
Cultivar name: ‘BB14-321NA-1’.
BACKGROUND AND SUMMARY
Blueberries are a well-known fruit enjoyed by many throughout the world. The novel blueberry variety in this application, ‘BB14-321NA-1’, is the first genotype from Berry Blue BBIP Genetics selected at the low-chill temperate environment of Nancagua Region of the O'Higgins (34° 43′58,89″ S; 71° 10′ 24,75″O) in Chile.
One example of an existing known blueberry variety is ‘Kestrel’ FL02-40 (U.S. Plant Pat. No. 21,719). Compared to ‘Kestrel’, ‘BB14-321NA-1’ has more vigor, it has earlier fruit in the season and has much larger fruit. The fruit of ‘BB14-321NA-1’ is large and well presented on the plant and is produced in one-year old shoots (in Chile) and in current season shoots (in Peru under tropical environment).
Comparing ‘BB14-321NA-1’ to ‘Stellar’ (brand name for ‘BB06-50FL-1’, U.S. Plant Pat. No. 30,445), the immature summer cane color ‘BB14-321NA-1’ is yellow green, compared to olive green in Stellar; the fruit of ‘BB14-321NA-1’ is earlier and more acidic, and flatter compared to ‘Stellar’. The mature leaves of ‘BB14-321NA-1’ are larger and more elongated than in Stellar and also it has a shorter leaf petiole.
Additional examples of an existing, patented blueberry variety are ‘Rocio’, U.S. Plant Pat. No. 20,374, ‘Kestrel’ (brand name for FL02-40, U.S. Plant Pat. No. 21,719) and ‘Stellar’. Compared with these varieties in Chile, ‘BB14-321NA-1’ has the largest fruit and the least levels of sugars (o Brix) as shown in Table 1, which provides fruit characteristics of ‘BB14-321NA-1’ compared to other commercial varieties grown in Chile.
