Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The accompanying color photographic illustration taken from a 4-year-old plant shows typical specimens of the foliage and fruit of the present new nectarine variety ‘Sunect30’. The illustration shows the upper and lower surfaces of the leaves and exterior and sectional views of the fruit. The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
