Description

The kernel-percentage cultivar. Slightly over half the weight of a nut in the shell comes out as kernel, against roughly 43 percent for ‘Jefferson’, and for anyone selling shelled that ratio is the whole economics of the crop — every point of shell is freight, storage and cracking paid for on material that gets thrown away.

It carries a recorded S-allele pair, S2 and S15, which is the sort of detail worth keeping. Hazelnut pollination is settled by allele identity, not by bloom charts alone, and a block laid out without checking the alleles can be busy and barren at once.
