What is the parentage of 'Northland', a half high blueberry?
Northland is a cross of Berkley and 19-H (a lowbush X Pioneer seedling cross)
There is no indication if the lowbush was a named variety.
Apparently Ashworth is in the pedigree of Chippewa.
Northland was developed in Michigan and Chippewa in Minnesota so I would not assume that Ashworth was used in Michigan.
