ABSTRACT:
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new, novel and distinct variety of peach tree,
Prunus persica
which has been denominated varietally as ‘Burpeachnineteen’.
The present variety of peach 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 ‘Burpeachnineteen’ 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 from a controlled cross of the yellow-fleshed freestone peach tree ‘P113-98’ (nonpatented), which was used as the pollen parent, and an early ripening, white-fleshed, clingstone nectarine tree, of known parentage (unpatented), which was used as the seed parent. One seedling, which is the present variety, exhibited especially desirable characteristics, and was marked for subsequent observation. After the 1999 fruiting season, the new present variety was selected for advanced evaluation and repropagation.
ASEXUAL REPRODUCTION
Asexual reproduction of the new and distinct variety of peach tree was accomplished by budding the new peach tree to ‘Nemaguard’ Rootstock (not-patented). This was performed by us in our experimental orchard which is 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
‘Burpeachnineteen’ is a new and distinct variety of peach tree, which is considered of large size, and which has vigorous growth. This new peach tree is also a regular and productive bearer of relatively large, firm, yellow fleshed, clingstone fruit, which have good flavor and eating qualities. This new tree has a medium chilling requirement of approximately 600 hours, and further produces relatively uniformly sized fruit throughout the tree. The fruit produced by this new variety has a non-melting flesh which makes it ideal for storage. In addition to the foregoing, the fruit of this new tree also appears to have good handling and shipping qualities. The ‘Burpeachnineteen’ peach tree bears fruit which are ripe for commercial harvesting and shipment on approximately May 8th to May 16
th
. In relative comparison to the seed parent, the present new variety of peach tree bears fruit which ripen about 10 days earlier at the same geographical location.
