|
A high proportion of good plus trees. Trees tend to be located in stands of superior overall form. Includes 3 trees from slower growing populations at Rannoch. Poor flowering in year 2. Better flowering in year 3 with significant seed collected

Plants exist as archived material at FR NRS.

A pilot collection made by FR in order mainly to test methodology. Some good plus trees, others poorer. Considerable numbers of plus trees from single stands. Some seed entered trade and was tested in Scottish seed source trials (E10) and shown to be quite slow growing
