Abstract
A new and distinct variety of apricot tree is provided which originated as a single bud sport or limb mutation of the `Castlebrite` cultivar (non-patented in the United States). The new cultivar has been named `Earli Sun`, and can be distinguished by its freestone fruits which are substantially similar in color and appearance to those of `Castlebrite` cultivar, yet are significantly larger in size, being ripening approximately two days later than those of the `Castlebrite` cultivar, and are markedly lower in the acidity of the flesh at harvest.
Description
The `Castlebrite` apricot (non-patented in the United States) was introduced in 1978 and has been met with much interest by commercial fruit growers in the San Joaquin Valley of California since its harvest date commonly precedes that of other apricot varieties grown in that area. See in this regard the article by D. W. Ramming and O. Tanner entitled `Castlebrite` Apricot appearing in HortScience 13(4):485 (1978). Accordingly, the `Castlebrite` apricot because of its early fruit maturity date has aided commercial growers, and currently represents one of major cultivars that is being grown to yield an early season apricot crop in California in spite of its recognized small fruit size and the marked tartness of the resulting fruit crop. Historically higher prices are reaized by growers who are able to supply the early season fresh fruit market, and there has been an ongoing quest to find new cultivars that exhibit commercially significant improved traits as well as an early harvest date.
The new apricot cultivar of the present invention was discovered during May of 1986 as a single bud sport or limb mutation of unknown causation that appeared on one of three main scaffolds of a four year-old tree of the `Castlebrite` cultivar located in an orchard of such variety situated on the northwest corner of Clarkson and Temperance Avenues near the City of Selma, County of Fresno, State of Calif. Had I not discovered and preserved the new cultivar of the present invention it would have been lost to mankind. Initially I was primarily attracted to the new variety because the distinctly larger fruit that it consistently exhibited.
It has been found and confirmed upon further testing that the new apricot cultivar of the present invention:
(a) forms early-maturing fruit on a consistent basis that is larger in size than that of the `Castlebrite` cultivar,
(b) forms fruit of low to mild acidity that is of a significantly lesser acidity than that of the `Castlebrite` cultivar, and
(c) exhibits a growth habit that is more vigorous than that of the `Castlebrite` cultivar.
Many other characteristics of the new variety are substantially identical to those of the parent `Castlebrite` cultivar.
The fruit of the new variety has been found to average approximately 70 to 100 percent larger in the axial and transverse diameters than the fruit of the `Castlebrite` variety. The fruit of the new variety has been observed to mature approximately two days later than that of the `Castlebrite` variety. The fruit flesh of the new vareity is noticeably lesser in acidity and thereby lacks the tartness of the `Castlebrite` variety as is readily apparent by subjective organoleptic evaluation. It has been found that the stone of the new variety is free of the flesh when eating ripe, but is considered to be only semi-free near the basal one-half of the pit when ready for commercial fresh fruit harvest, whereas the stone of the `Castlebrite` variety tends to be free at both stages of ripeness.
The pattern of fruit reipening between the new variety and the `Castlebrite` variety tends to be different. More specifically, the fruit of the new variety begins to ripen near the pit and commonly requires a greater length of time for the entire flesh to ripen. This commonly is demonstrated by the longer time required for the development of the flesh color from pale greenish-yellow to orange throughout the entire flesh. Accordingly, the new variety can be harvested with more green skin coloration being present than the `Castlebrite` variety.
In a side-by-side comparison planting, the new variety has been observed to yield heavy crops over a six year period, whereas the parent `Castlebrite` variety has produced light crops in two of those years thereby suggesting that the new variety may crop more consistently than the `Castlebrite` variety.
The growth habit of the new variety tends to be more vigorous than that of `Castlebrite` variety. Also, the new variety tends to form larger leaves than the parent `Castlebrite` variety. Additionally, in early Spring, the current season's vegetative growth of the new variety tends to be more orange-yellow in coloration than that of the `Castlebrite` variety. This difference in the coloration of the vegetative growth becomes indistinguishable as the season progresses.
Although the causation of the mutation that produced the new variety is unknown, such mutation may have been the result of an increase in ploidy that has resulted in the creation of the more vigorous tree and fruit character. However, reductions in fertility that often are exhibited by polyploids have not been manifested in the fruit set of the new variety and the cropping ability to date has been more than adequate. Seed viability and the chromosomal compliment have not been investigated.
The new variety of the present invention has been asexually reproduced by budding onto Nemaguard peach rootstock beginning in lae May of 1986. During the following winter, the resulting trees were dug and were transplanted to a different orchard site near the intersection of Conejo and Fowler Avenues, south of the City of Selma, County of Fresno, State of California. The asexually reproduced trees were planted adjacent to comparable trees of the `Castlebrite` variety that were also propagated onto the same Nemaguard peach rootstock. Fruiting observations beginning in 1989 and thereafter, have shown that the characteristics of the asexually reproduced trees are stable and are identical to those of the original mutated limb and in the indicated respects are substantially different than those of the parent `Castlebrite` variety.
The new cultivar has been named the `Earli Sun` cultivar.
The accompanying photographs show typical specimens of the new cultivar as depicted in color as nearly true as it is reasonably possible to make the same in color illustrations of this type. All specimens were obtained from trees of the `Earli Sun` cultivar growing in an orchard located near the intersection of Conejo and flower Avenues, south of the City of Selma, County of Fresno, State of Calif.
FIG. 1 illustrates typical foliage and mature fruit of `Earli Sun` apricot of the present invention that was harvested on May 14, 1992 with some of the fruit being divided along the suture plane so as to reveal the flesh color and the freeness of the pit. The photograph was taken on May 22, 1992 following the cold storage of the fruit.
FIG. 2 illustrates at the left five mature fruits of the parent `Castlebrite` apricot that were harvested on May 14, 1992, and at the right five mature fruits of the new `Earli Sun` apricot that were harvested on May 17, 1992. The photograph was taken on May 22, 1992 following the cold storage of the fruits. Significant differences in fruit size, and the similarity in fruit coloration are apparent. The fruit coloration is velieved to be more accurately depicted in FIG. 1 than in FIG. 2.
FIG. 3 illustrates at the left the more vigorous growth habit of a typical `Earli Sun` tree, when compared at the right to that of a typical `Castlebrite` tree. The photograph was taken on Jun. 4, 1994.
