Title: Kiwi plant named ‘HFY01’

Description:
Latin name of the genus and species of the plant claimed:  Actinidia chinensis  pl. 
     Variety denomination: ‘HFY01’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Actinidia  plant, botanically known as  Actinidia chinensis  pl of the Actinidiacea family, and hereinafter referred to by the variety denomination ‘HFY01’. 
     The new  Actinidia  cultivar is a product of a controlled breeding and pollination program conducted by the inventor, in Xia Yuan Village, Shifang county, Sichuan Province, China. The objective of the breeding and pollination program was to develop a new  Actinidia  cultivar with a dark yellow fruit flesh color. 
     The new  Actinidia  cultivar originated from a open pollination made by the inventor(s) in Xia Yuan Village, Shifang County, Sichuan province, China. The female or seed parent is the  Actinidia chinensis  pl. cultivar designated JXFX-CK-04136, which was discovered as a seed collected from trees growing in the wild in Fengxin county, Jiangxi province, China, in 2004 and subsequently grown in a cultivated area. The variety was developed through open pollination and the male or pollen parent is not known. 
     Seeds that produced the female parent JXFX-CK-04136 were sown in February 2005 and 300 seedlings were then planted out in a field in Shifang County, Sichuan Province, China in February 2005. The plants were pollinated through open pollination of a mix of  Actinida chinensis  pl. and the male or pollen parent is not known. The seedlings first fruited in in April 2008. A total of 1 female seedlings were propagated by graft in October 2009. The new  Actinidia  cultivar was selected by the inventor(s) in a controlled environment in 2010 in Shifang County, Sichuan Province, China. 
     Asexual reproduction of the new  Actinidia  cultivar by grafting on to rootstocks of  Actinidia deliciosa  pl. was first performed in April 2012 in a kiwifruit research station in Shifang county Sichuan province, China, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type. 
     BRIEF DESCRIPTION OF THE INVENTION 
     The following traits have been repeatedly observed and are determined to be unique characteristics of ‘HFY01’ which in combination distinguish this  Actinidia  as a new and distinct cultivar:
         1. Very strong growth habit. In soil of PH 5-6.5 and annual average temperature of 16-18° C., the claimed variety will fruit in the second year after grafting and can produce up to 20-30 t/ha of fruit by the fourth year of fruiting.   2. Flowering time and blooming period. Flowering time is in about end-April in Sichuan Province, China and the blooming period is about 5 to 8 days.   3. Harvesting time. The harvesting time is in early-December in Sichuan Province, China.   4. Fruit Shape and Size. The general fruit shape is long-trapezium with a weakly depressed stylar end. The average fruit weight is 85 g and maximum fruit weight is 120 g;   5. Pest resistance. The claimed variety shows strong resistance to  Pseudomonas syringae  pv.  actinidiae  (PSA).       

     In comparison to the parental variety, ‘JXFX-CK-04136’ (unpatented), ‘HFY01’ differs primarily in the traits listed in Table 1.

     DETAILED BOTANICAL DESCRIPTION 
     The new  Actinidia  cultivar ‘HFY01’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the  Actinidia.    
     The aforementioned photographs, together with the following observations, measurements and values describe plants of ‘HFY01’ as grown outside in a field in Shifang county, Sichuan Province, China, under conditions which closely approximate those generally used in commercial practice. 
     Unless otherwise stated, the detailed botanical description includes observations, measurements and values based on 4 year old ‘HFY01’ plants grown in the field in Shifang county, Sichuan Province, China from 2009 to 2013. Quantified measurements are expressed as an average of measurements taken from a number of plants of ‘HFY01’. The measurements of any individual plant, or any group of plants, of the new cultivar may vary from the stated average. 
     Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 4 th  Edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 10:00AM in Shifang county, Sichuan Province, China. 
     All of the plants of ‘HFY01’, insofar as they have been observed, have been identical in all the characteristics described below.

It has a shelf life up to 2 weeks without losing firmness and juiciness.     Maturity when described .—Harvest time is about the end of October in Sichuan Province, China. Fruit is ripe for eating at harvest.     Firmness .—About 5-7 kg/cm 2 .     Maturity period after full bloom .—About 170-180 days after full bloom around April 25 th .     Type .—Berry.     Average fruit weight and size .—Weight: About 85 g. Height: About 55 mm. Diameter (at widest point): About 49 mm. Diameter (at narrowest point): About 47 mm.     Fruit shape .—General shape: long-trapezium. Styler end description: weakly depressed. Shoulder shape of stalk end: rounded. Cross-section shape at median: transverse elliptic.     Skin .—Firmness (at picking time): 4 to 5 kg/cm 2 . Texture: smooth; lenticels are inconspicuous. Pubescence: none. Color: At harvest: RHS 164B. During ripening: RHS 164B. At maturity for consumption: RHS 164B.     Flesh  ( at maturity for consumption ).—Texture: tender and juicy. Aroma: good. Sugar content (at picking time): 17 to 18 Brix. Acidity/Starch (at picking time) 1 to 1.4 g/lt. Outer pericarp: Color: RHS 17A. Inner pericarp (locules): Number (per fruit): About 45. Shape: oblong. Length: About 55 mm. Width: About 40 mm. Color: RHS 17B. Core: Shape and symmetry: triangle. Diameter (maximum): About 8 mm. Diameter (minimum): About 5 mm. Woody spike: absent. Color: RHS 155A.       
       Seeds:
             Number per fruit .—About 1500-2000.     Shape .—Cylindrical.     Length .—About 1 mm.     Width .—About 0.5 mm.     Texture .—Striped, smooth.     Color at maturity  ( in flesh ).—RHS 183A.     Color at maturity  ( when dried ).—RHS 164A.       
       Cultivar use: Fresh market.   Disease/pest resistance: Resistance to  Pseudomonas syringae  pv.  actinidiae  (PSA) is stronger than the known kiwi varieties ‘JINGFEN’, ‘HOR16A’, and ‘HONGYANG’.   Disease/pest susceptibility: Some susceptibility to  Pseudaulacaspis pentagona  (White Peach Scale);  Adoxophyes orana  Fisher (Summer fruit tortrix);  Acleris fimbriana  Thunberg (Yellow Tortrix Moth); and  Anomala corpulenta  Motsch. (Scarabaeidae).   Winter hardiness: Tolerant to temperatures down to −5° C. without observed damage to wood and buds of dormant  Actinidia  plants; but open flowers and young fruitlets are killed by exposure to 5° C., depending on the length of exposure.   Drought/heat tolerance: Tolerant to temperatures up to 35° C., growth is limited by drought periods without irrigation.   Events:
             Time of vegetative budbreak .—Mid-February in Sichuan Province, China.     Time of beginning of flowering .—End-April in Sichuan Province, China.     Time of maturity for harvest .—End of October in Sichuan Province, China.
