ABSTRACT:
BACKGROUND OF THE NEW VARIETY
Botanical classification:
Prunus persica.
Variety denomination ‘Burnectseven’.
The present invention relates to a new, novel and distinct variety of nectarine tree,
Prunus persica
var. (
nucipersica
), which has been denominated varietally as ‘Burnectseven’. The present variety of nectarine tree resulted from an on-going program of fruit and nut tree breeding. The purpose of this program is to improve the commercial quality of deciduous fruit and nut varieties and rootstocks by creating and releasing promising selections of prunus, malus and regia species. To this end we make both controlled and hybrid cross pollinations each year in order to produce seedling populations from which improved progenies are evaluated and selected.
The seedling ‘Burnectseven’ was originated by us from a population of seedlings grown in our experimental orchards located near Fowler, Calif. The seedlings, grown on their own roots, were the result of a controlled cross of the nectarine tree ‘Summer Red’ (U.S. Plant Pat. No. 5,211) which was used as the seed parent and the nectarine tree ‘Diamond Ray’ (U.S. Plant Pat. No. 8,948) which was used as the pollen parent. One seedling, which is the present variety, exhibited especially desirable characteristics and was marked for subsequent observation. After the 1997 season, the new present variety was selected for advanced evaluation and repropagation.
ASEXUAL REPRODUCTION
Asexual reproduction of the new and distinct variety of nectarine tree was accomplished by budding to ‘Nemaguard’ Rootstock (non-patented). This was performed by us in our experimental orchard located near Fowler, Calif. Subsequent evaluations have shown those asexual reproductions run true to the original tree. All characteristics of the original tree and its fruit were established and appear to be transmitted through succeeding asexual propagations.
SUMMARY OF THE VARIETY
‘Burnectseven’ is a new and distinct variety of nectarine tree, which is of large size, and which has vigorous growth, and is a regular and productive bearer of large, firm yellow flesh, clingstone fruit with good flavor and eating quality. The tree has a medium-high chilling requirement of approximately 700 hours. The tree also produces relatively uniformly sized fruit throughout the tree with a high degree of red skin coloration, and firm flesh. The fruit appears to have good handling and shipping quality. Still further, the ‘Burnectseven’ nectarine tree bears fruit that is ripe for commercial harvesting and shipment on approximately July 15 to July 22. In comparison to the seed parent ‘Summered’ Nectarine, (U.S. Plant Pat. No. 5,211) the new variety ripens 15 or more days earlier.
