Claims
What is claimed is:
1. A new and distinct cultivar of Mangifera plant named
`302216THOM` as herein illustrated and described.
Description
Latin name of the genus and species: Mangifera indica.
Variety denomination: `302216THOM`.
BACKGROUND OF THE INVENTION
The new Mangifera cultivar is a product of a planned breeding
program conducted by the inventor, Tim Thompson, in Camarillo,
Calif. The objective of the breeding program was to produce new
Mangifera indica varieties with greater resistance to diseases and
cold temperatures. The open pollination resulting in this new
variety occurred during 1996.
The seed parent is unknown, as the inventor bulk collected seed as
part of an open pollination breeding program consisting of several
potential seed and pollen parents, all of which are Mangifera
indica varieties. The new variety resulted from seed planted in
1994. The inventor observed the seedlings during several seasons,
and made a final selection of `302216THOM` during 2008 at a
non-commercial nursery in Camarillo, Calif.
Asexual reproduction of the new cultivar was performed by grafting
vegetative cuttings onto Mangifera indica `Turpentine`
(unpatented). This was first performed at a commercial nursery in
Ventura County, Calif. in May of 2013 and has shown that the unique
features of this cultivar are stable and reproduced true to type in
successive generations.
SUMMARY OF THE INVENTION
The cultivar `302216THOM` has not been observed under all possible
environmental conditions. The phenotype may vary somewhat with
variations in environment such as temperature, day length, and
light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are
determined to be the unique characteristics of `302216THOM`. These
characteristics in combination distinguish `302216THOM` as a new
and distinct Mangifera cultivar: 1. Good adaptation to Southern
California growing conditions. 2. Tolerance for cold to
approximately 28.degree. F. 3. Resistance to powdery mildew. 4.
Rich gold colored skin of the fruit. 5. Heart-shaped fruit.
PARENTAL COMPARISON
As the actual parents are unidentifiable, the inventor is unable to
make any comparison.
COMMERCIAL COMPARISON
Plants of the new cultivar `302216THOM` are comparable to the
variety Mangifera `Kent`, unpatented. The two Mangifera indica
varieties are similar in most horticultural characteristics;
however, plants of the new variety `302216THOM` differ in the
following characteristics: 1. Plants of the new variety can survive
cold temperatures that would damage or kill similar aged plants of
`Kent`. 2. Blossoms of the new variety are much less susceptible to
powdery mildew than those of `Kent`. 3. The new variety reliably
produces a fruiting crop in Southern California, whereas plants of
`Kent` are not known to reliably produce fruit under the same
environmental conditions. 4. Skin color of fruit of the new variety
is typically rich gold color, whereas skin color of fruit of the
variety `Kent` is normally green on most fruit. 5. When grown in
shaded conditions, the fruit skin color of `Kent` is green, whereas
`302216THOM` produces a fruit with a rich gold skin color even when
grown under the shaded canopy of the tree.
Plants of the new cultivar `302216THOM` are comparable to the
variety Mangifera `Haden`, unpatented. The two Mangifera indica
varieties are similar in most horticultural characteristics;
however, plants of the new variety `302216THOM` differ in the
following characteristics: 1. Plants of the new variety can survive
much colder temperatures that would damage or kill similar aged
plants of `Haden`. 2. Blossoms of this variety are relatively
unaffected by powdery mildew while blossoms of `Haden` suffer
fungal damage especially during our cool, damp Spring weather. 3.
The new variety reliably produces a fruiting crop in Southern
California, whereas plants, of `Haden` do not reliably produce
fruit under the same environmental conditions. `Haden` is typically
does well in South Florida and Mexico conditions. 4. Skin color of
fruit of the new variety is typically rich gold. Skin color of
fruit of `Haden` is typically golden with a strong red blush. 5.
The variety `Haden` is known to have significant susceptibility to
fungal diseases. The new variety is significantly more tolerant of
fungal diseases than `Haden`.
Plants of the new cultivar `302216THOM` are comparable to the
variety Mangifera `301215THOM`, co-pending application Ser. No.
14/757,210. The two Mangifera indica varieties are similar in most
horticultural characteristics; however, plants of the new variety
`302216THOM` produce more inflorescence per tree, on average 100 to
150 compared to 60. Additionally, `302216THOM` produces fruit with
different characteristics, as follows: 1. Fruit of `302216THOM` are
heart-shaped and have an average length of 15 cm and average
diameter of 5 cm; fruit of this comparator are elongated oval
shaped and have an average length of 16 cm and diameter of 8 cm. 2.
The stalk cavity of `302216THOM` is nearly flat, stalk cavity of
this comparator is slightly recessed. 3. Fruit color of
`302216THOM` is Yellow 13B and 13C with mottling Orange 26B and
blush colored Orange-Red N34C. This comparator has a base color of
the fruit skin of Yellow-Orange 23A and 23B, blush color is near
Red 42A.
Plants of the new cultivar `302216THOM` are comparable to the
variety Mangifera `201230THOM`, U.S. Plant Pat. No. 27,080. The two
Mangifera indica varieties are similar in most horticultural
characteristics; however, plants of the new variety `302216THOM`
produce fruit with different characteristics, as follows: 1. Fruit
of `302216THOM` is heart-shaped, shape of this comparator is
elongated. 2. `302216THOM` produces more fruit per plant, typically
than this comparator 3. Fruit color of `302216THOM` is Yellow 13B
and 13C with mottling Orange 26B and blush colored Orange-Red N34C.
Fruit of this comparator are 80 to 90% red, RHS 53C and 53D, with a
minor secondary color near Orange-Red 33B.
