Description

Botanical classification: Vaccinium corymbosum L.
Variety denomination: The new plant has the varietal denomination ‘Plablue 15122’.
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of European Community Plant Variety Office Application No. 2018/2076, for a blueberry variety named ‘Plablue 15122’, filed on Aug. 9, 2018, the entirety of which is incorporated by reference herein.
BACKGROUND
Disclosed herein is a new and distinct southern highbush blueberry variety (Vaccinium corymbosum L.). The varietal denomination of the new variety is ‘Plablue 15122’. The new variety of blueberry was created in a breeding program by crossing two parents; in particular, by crossing as seed parent an undistributed blueberry parent designated 14.09.001 (unpatented) and as pollen parent an undistributed blueberry parent designated 11.024.001 (unpatented). Female and male are selections from breeder's program. Both parental varieties are property and have not been commercialized.
The new variety was grown and asexually propagated by softwood cuttings in Segovia, Spain, 3° 59′W., 41° 22′N., 2742 feet elevation. Clones of the new variety were further asexually propagated and extensively tested. This propagation and testing has demonstrated that the combination of traits disclosed herein which characterize the new variety are fixed and retained true to type through successive generations of asexual reproduction.
The growing period in Huelva, Spain, where the observations on primocane production were made, is between about November 20 and June 22 of the following year.
SUMMARY
The present invention relates to a new and distinct southern highbush blueberry variety. The varietal denomination of the new variety is ‘Plablue 15122’, that produces and maintains a medium vigorous plant with consistent fruit production from the end of January through the end of May. Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include a semi upright plant growth habit, and very abundant production of medium fruit-size, round shaped and very firm fruit.
The new blueberry plant variety ‘Plablue 15122’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environmental and cultural practices such as temperature and light intensity without, however, any variance in genotype.
