The present invention relates to a new, novel and distinct variety of peach tree, which has the denominated varietally as `Burpeachtwo`. The `Burpeachtwo` Peach Tree produces an exceptionally high quality, clingstone peach which is mature for harvesting and shipment in late season. Another unique aspect of the `Burpeachtwo` Peach Tree is that it yields a firm peach which exhibits very high eating quality as compared with the other peach varieties which mature at approximately the same time. In this regard, the `Burpeachtwo` ripens approximately August 1st which is approximately 5-6 weeks before the ripening date of the `Autumn Lady`, the pollen parent; and approximately 7-9 days after the `Summer Lady` peach tree, the seed parent.
The present variety of peach tree resulted from an ongoing 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 selections of prunus, malus and regia species. To this end, we make both controlled and hybrid crosses each year in order to produce seedling populations from which improved progenies are evaluated and selected. The seedling `Burpeachtwo` was originated by us in 1993, and chosen from among a population of seedlings which were derived from a controlled cross of the Peach Tree `Autumn Lady`, (U.S. Plant Pat. No. 4,398) which was used as the pollen parent; and the `Summer Lady` Peach Tree, (U.S. Plant Pat. No. 5,865), which was used as the seed parent. The resulting seeds from this controlled cross were planted in the spring of 1994. The new variety of peach tree was selected from among the seedlings then growing in the experimental orchards of the Assignee of the present application near the city of Fowler, Calif., County of Fresno in the San Joaquin Valley. The Peach Tree `Burpeachtwo` was subsequently marked for observation and noted at that time as having exceptional characteristics. It has been subsequently and repeatedly evaluated during the 1995-1999 fruiting seasons. After the 1995 season, the Peach Tree `Burpeachtwo` was selected for advanced evaluation and repropagation.
The new variety Peach Tree `Burpeachtwo` was grafted into two different and existing `Nemared` (non patented) peach rootstocks in February of 1996. The `Nemared` rootstocks were planted in 1995. These rootstocks provide the means by which more information regarding the new variety could be derived. Scionwood from the original seedling of the Peach Tree, `Burpeachtwo` was subsequently collected and grafted in the evaluation plot on the assignees experimental farm previously described. Fruit from the resulting propagation has been evaluated for each of the 1997, 1998 and 1999 fruiting seasons. These subsequent evaluations have clearly demonstrated that the repropagated trees are true to the characteristics of the original seedling in all observable aspects.
The `Burpeachtwo` Peach Tree is characterized as to novelty by producing late season fruit having a very high quality; which are very firm; and which also have an attractive exterior coloration. In this regard, the present variety of peach tree bears clingstone fruit which are ripe for commercial harvesting and shipment on approximately August 1 to August 10. These harvesting dates are approximately the same harvesting period as the common commercial freestone peach tree `O'Henry` (U.S. Plant Pat. No. 2,964). The present variety of peach tree distinguishes itself from the `O'Henry` Peach Tree however, by providing fruit having a bright exterior coloration, exceptional firmness, a clingstone trait and an extremely flavorful and juicy flesh quality. Further, the `Burpeachtwo` Peach Tree distinguishes itself from the `O'Henry` Peach Tree in that the `O'Henry` peach has a background color that can vary from a greenish to yellow-green hue, while in contrast, the fruit produced by the `Burpeachtwo` Peach Tree has a background color that is yellow-orange to orange in color.
The accompanying drawing is a color photograph of a characteristic twig bearing typical leaves; several leaves showing both the dorsal and ventral coloration thereof; and several mature fruit showing their external coloration sufficiently matured for harvesting and shipment. Additionally one fruit of the subject variety is dissected in the equatorial or cheek plane to illustrate the flesh and stone characteristics.
Referring more specifically to the pomological details of the new and distinct variety of peach tree, the following has been observed under the ecological conditions prevailing at the assignee's orchards which are located at 6705 South Clovis Avenue near the town of Fowler, county of Fresno, state of California.
