DETAILED DESCRIPTION

(9) The following is a detailed description of the new variety with colour terminology in accordance with The Royal Horticultural Society Colour Charts (R.H.S.C.C.). The new Malus variety Seaton99 has not been observed under all possible environmental conditions.

(11) The planting site and climatic conditions closely approximate those generally used in commercial production of pipfruit, and the land areas in the vicinity have successfully been deployed in the production of pipfruit since the settlement of the Region, so that the location is generally viewed as a suitable site for commercial production.

(12) The climate is in the temperate zone with summer temperatures generally below 30 deg C. and maximum 35 deg C. Winter temperatures range 7-16 deg C. with minimums minus 5-7 deg C.

(13) The soil is variable and of modest fertility, being a mix of recent alluvial soils with clay type sub-soil, with fertility maintained by applications of fertiliser applied annually.

(14) Trees are irrigated by drip irrigation when necessary. Annual rainfall is 900-1200 mm per year.

(15) The trial blocks are substantially planted on CG 202 rootstock with the first commercial planting trial block now in 6.sup.th year. Plantings are spaced 1.5 M between tree and 3.5 m row width giving a tree density of 2000 trees per hectare. All trees have performed identically in respect of fruit characteristics.

(16) The type of bearing is early, being the first harvestable variety. Productivity is good with regular and heavy flowering and no bi-annual flowering evident.

(22) Branches number about 15 per tree and are angled generally 45-75 deg F. Natural growth tendencies have been suppressed by tying pendant as part of tree training management. Typical branch length is approximately 780 cm, with a diameter of approximately 19.5 cm. Texture is smooth. Interlode length=320 cm. Colour=grey, RHS 198A.

(23) Leaves are evenly spaced along plant growth shoots. Leaf shape is conically elongated from a broader base to a sharp apex. The margin is tightly serrated. The front texture is waxy and the rear displays a matte finish. Leaves have an even venation pattern with staggered joints on each side from the main rib. Front surface colour is medium green RHS 146A. Reverse surface colour is a pale green RHS 148A.

(24) Petiole length=41 cm, with a diameter of 2 cm. Petiole colour is light brown RHS 152B.

(25) Blooming time in Redwood Valley is from early October until the 3rd week of October with staggered later heavy flowering on one year old wood. The flowers are borne in clusters with approximately 6 flowers per cluster. Flowers can also be borne singly. The average flower depth is 15 mm and flower diameter is 35 mm.

(26) The flower bud shape is bulbous, round with an average bud length of 13 mm and bud diameter of 9 mm. The flower bud colour is 134B. The average number of petals is 5, with an average petal length of 20 mm and petal width of 12 mm. The petals have an oval shape. The petal apex is rounded with no distinct point (rotundifolus). The petal margin is entire (forma integra). The abaxial petal texture is soft, smooth and lightly veined, while the adaxial petal texture is soft and veined. The abaxial and adaxial surfaces of the petal both have a colour of 62D.

(27) The average number of sepals is 5, with an average sepal length of 9 mm and sepal width of 4 mm. The sepals have a triangular shape to a pointed tip. The sepal apex is sharp and pointed. The sepal margin is fringed by hairs (ciliatus). The abaxial sepal texture and the adaxial sepal texture are both heavily covered by hairs. The abaxial and adaxial surfaces of the sepal both have a colour of 134B.

(28) Fruit maturity commences second week of February which is about 125 days after flowering.

(29) The harvest window is from early- mid February until early March.

(31) Fruits are conical-truncated with an average fruit height of 70 mm, fruit diameter of 77 mm, and weight around 240 gm.

(32) Stem length is around 27 mm with a diameter of 2.7 mm. Colour of the stem is 21C.

(39) The fruit core is oblongated. Approximately 5 fruit locule per fruit, where the fruit locule form contains segregated interconnecting chambers. The average fruit locule length is 18 mm and average fruit locule width is 5 mm. Seeds per fruit is about 6 and per locule 1-2. The seeds are oblong and pear shaped with a smooth texture and a colour of 177A. Seed length is 7.7 mm-width 4.7 mm.

(40) The typical number of pistils is 5 and the average pistil length is 13 mm. The average anther length is 2.5 mm with a colour of 1C. The average stigma length is 0.5 mm with a colour of 142B. The average style length is 8 mm with a colour of 142C. The average ovary length is 3 mm with a colour of 130A. The pollen amount is abundant and the pollen has a colour of 14A.

(41) Propagation is from budding and grafting on GC202 (patented) rootstock.

(42) Light intensitiesfull sunlight or slight shade. A small trial area using light-reflective cloth has been conducted with anticipated outcome of increased percentage of foreground colour. The trial area will be increased.

(43) Pruning requirements are similar to heritage GALA, requiring removal of strong upright growth, and systematic renewal of fruiting wood. The trees perform well with branches trained into a pendant position of approximately 45% below horizontal. Flower numbers are very high and require heavy blossom thinning over the bloom period.

(44) Tree vigour is moderate with upright form and good ramification.

(45) Main branches develop with flat angles around 45%-50% if not trained down.

(46) Climatic hardiness appears normal tolerance for planted site which experiences summer temperatures in the mid to high 30's (Celsius) and winter temperatures down to 10 deg C.

(47) Disease/pest susceptibility is evident to black spot (scab), and powdery mildew at increased incidence requiring dedicated control.

(48) Climatic hardiness appears normal tolerance for planted site which experiences summer temperatures in the mid to high 30's and winter temperatures down to 10 deg C.
