Citrus hybrida/Mandarin Orange Tree
cv. Garbi
Citrus crops including Mandarin Oranges are recognized to be important to the agricultural economy in many parts of the world.
The new hybrid Citrus cultivar of the present invention was created during the spring of 1996 at Moncada, Valencia, Spain, when two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics required to produce quality late-ripening seedless fruit. The female parent (i.e., the seed parent) was the ‘Fortune’ Mandarin cultivar (non-patented in the United States). ‘Fortune’ is recognized to be a diploid formed by the hybridization of C. clementina×C. tangerina. The male parent (i.e., the pollen parent) was the ‘Murcott’ tangor cultivar (non-patented in the United States). ‘Murcott’ is a diploid of C. reticulata×C. sinensis. In order to achieve the cross, the anthers of the ‘Murcott’ tangor cultivar were removed from flowers collected during pre-anthesis and were dried in Petri dishes over silica gel in a desiccator at −20° C. The controlled cross-pollination was carried out by applying one anther from the male parental plant to a receptive stigma of flowers of approximately 100 female parental plants. From these female parental plants, 45 fruits were collected that contained 129 small seeds. Embryos numbering 122 were isolated from these seeds and were cultured in vitro. Small plants numbering 116 were recovered and were maintained. When analyzed by the use of flow cytometry, each of the small plants was confirmed to be a triploid. The resulting plants were transferred to standard potting mix and were grown under greenhouse conditions until September, 1998. Each plant next was grafted on ‘Carrizo’ Citrange rootstock (non-patented in the United States), which is recognized to be a cross of C. sinensis×Poncinus trifoliate, and was planted in the field for detailed evaluation. These plants first flowered during the spring of 2002, and a single plant of the present invention was selected during 2004, and was further grafted (as described) for further evaluation. The new plant initially was designated IVIA TRI 1.
It was found that the new triploid Mandarin Orange hybrid plant of the present invention displays the following combination of characteristics:
(a) displays a vigorous and drooping growth habit,
(b) forms dark green leaves, and
(c) forms attractive substantially homogeneous easy-to-peel obloid-shaped late-maturing fruit having a large diameter which is substantially seedless with an excellent mildly acidic flavor and a pleasant aroma.
The new cultivar readily can be distinguished from its parental cultivars. More specifically, each parent plant is a diploid, unlike the triploid character of the new cultivar of the present invention.
The new cultivar also can be readily distinguished from the ‘Safor’ cultivar (U.S. Plant patent application Ser. No. ______, filed concurrently herewith). The ‘Safor’ cultivar displays a more erect drooping growth habit and forms fruit of medium-late maturity whereas the present cultivar forms fruit of late maturity.
The asexual reproduction of the new cultivar of the present invention by grafting on ‘Carrizo’ rootstock at Moncada, Valencia, Spain, has confirmed that the combination of characteristics is stable and is strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new cultivar of the present invention undergoes asexual propagation in a true-to-type manner.
The new plant of the present invention has been named ‘Garbi’.
The accompanying photographs show as nearly true as it is reasonably possible to make in color illustrations of this character, typical specimens of the new cultivar. The plant was grown at Moncada, Valencia, Spain, and was grafted on ‘Carrizo’ rootstock.
The description is based on the observation of plant of the new cultivar while grafted on ‘Carrizo’ rootstock and growing outdoors at Moncada, Valencia, Spain. The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), London, England. Common color terms are to be accorded their customary dictionary significance.
The new ‘Garbi’ cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
