The Gisborne variety was selected as a potential late polliniser from a tree at the DSIR research station at Gisborne, New Zealand.
It is vigorous with few suckers forming a large spreading tree.
The husk is about 50% longer than the nut but is strongly split and most nuts fall free of the husk.
It is moderately susceptible to bacterial blight but seems to be resistant to big bud mites.
Pollen shedding and flowering are midseason.
Performance data for Gisborne is limited but it has yielded well in the Bay of Plenty and Wairarapa.
The nuts are ribbed and dull light brown, with a heavy fibre cover on the kernel.
The kernels blanch well.
Percent kernel 38-40%.
Gisborne is very similar to Alexandra and reports of early flowering “Alexandra” trees in the 1980′s usually turned out to be Gisborne.
The most distinct differences are the earlier dates for pollen shedding and bud burst for Gisborne.
