Nectarine tree named ‘Prima Diamond 19’

Abstract

‘Prima Diamond 19’ produces large fruits that mature approximately mid-July in the San Joaquin Valley of Central California. The fruit being approximately similar to ‘Summer Fire’ (U.S. Plant Pat. No. 7,506) and ‘July Red’ (U.S. Plant Pat. No. 5,663) in date of maturation. However, the new variety distinguishes from ‘Summer Fire’ and ‘July Red’ in numerous respects including the fruit having more exterior red blush color, smoother blemish-free skin surface, lower susceptibility to brown rot, sweeter, fuller flavor and longer post-harvest life. In addition, the tree produces consistently higher levels of production than ‘Summer Fire’ and ‘July Red’.
