Leaf of GRAD Series 2 Pinot noir clone nursery code labelled ‘CSTWS’. This shows the typical UCD4 Pinot noir line leaf: dusky mid-green, only moderately 5-lpbed, and slightly wider than it is deep. This selected genetic line traces back to material given to Corbans in the mid- to late-1960s by Frank Berrysmith. This lime may therefore be the closest of all the GRAD Series 2 clones to the original 1963 import, although I still believe it is more likely than not that it was heat-treated in quarantine. This means that what was released in April 1965 was not the original U.C.D. material but the N.Z. heat-treated version — and thus it was always a distinct, N.Z.-created, clone right from release. The GRAD clonal line from this source is continuing to be held in my nursery for further development.
