ABSTRACT:

BOTANICAL/COMMERCIAL CLASSIFICATION
Prunus salicina
/Japanese Plum.
VARIETAL DENOMINATION
cv. ‘Aphrodite’.
SUMMARY OF THE INVENTION
The present invention is directed to a new and distinct Japanese Plum (i.e.,
Prunus salicina
) cultivar that originated near Sanger, Calif. during the course of a controlled breeding program. More specifically, during February, 1991, the ‘Shayna’ cultivar (non-patented in the United States) was crossed with the ‘Santa Rosa’ cultivar (non-patented in the United States). The parentage of the new cultivar can be summarized as follows:
‘Shayna’בSanta Rosa’.
Eighty seeds were produced from this cross and were planted near Sanger, Calif. during 1992 and germinated and grew to yield seedling plants during 1992 and 1993. During the 1994 growing season the seedlings produced a substantial quantity of fruit and were studied in detail. A single plant of new cultivar was selected and was carefully preserved.
It was found that the new Japanese Plum cultivar of the present invention exhibits the following combination of characteristics:
(a) Forms large well-colored fruit of excellent firmness and flavor that is larger in size than that of the ‘Santa Rosa’ cultivar,
(b) Forms fruit that ripens a few days after that of the ‘Santa Rosa’ cultivar, and
(c) Is a regular bearer with greater fruit productivity than the ‘Santa Rosa’ cultivar.
During the spring of 1995 the new cultivar of the present invention was first asexually propagated by grafting onto one year-old ‘Marianna’ plum rootstock (nonpatented in the United States) near Sanger, Calif. The resulting asexually reproduced trees produced few fruit in 1996, and produced the first significant fruit crop in 1997. Such significant fruiting has continued in each year thereafter. It has been confirmed that the characteristics of the new cultivar are strictly transmitted to the next generation following such asexual propagation.
The new cultivar of the present invention can be readily distinguished from its ‘Santa Rosa’ cultivar parent by the formation of generally larger fruit, the formation of firmer fruit at commercial maturity, overall greater fruit productivity, and a later fruit maturity by a few days. Additionally, the new cultivar can be readily distinguished from its ‘Shayna’ cultivar parent by differences in ripening time, fruit attachment to the stone, fruit size, fruit color, productivity, and pollination requirements. The ‘Shayna’ cultivar commonly ripens much later during the first week of August, is complete freestone, forms larger fruit that is lighter purple with a lesser coloration of the fruit surface, is less productive and an erratic bearer, and bears self-incompatible flowers.
The new cultivar of the present invention has been named ‘Aprodite’.
