New red- and yellow-fleshed kiwifruit cultivars

After 15 years of breeding, Sichuan Province Academy of Natural Resource Science and Sichuan Hua Sheng Agriculture Co. Ltd. have bred an excellent new red-fleshed kiwifruit cultivar, ‘HFR18’, and a new yellow-fleshed kiwifruit cultivar, ‘HFY01’. The new red kiwifruit cultivar ‘HFR18’ is a diploid and was bred from a cross using ‘Hongyang’ as female parent and ‘SF0612M’ as male parent. The general fruit shape is ovate, with a slightly depressed stylar end. The average fruit weight is 77 g and maximum fruit weight is 110 g (without use of plant hormone CPPU). The flesh is yellow-green when ripe, and the colour of the locules in the inner pericarp is a deep red. The fruit has a sweet taste with a ripe soluble solids content of 17.1%, total sugar content of 7.26% and total acid (citric acid) content of 1.43%. Fruit is nutritious, with a vitamin C content of 184 mg 100 g^‑1. Flowering time in Sichuan is mid-April, and the blooming period is about 5-8 days. The harvesting time is early to mid-September in Sichuan. Plant vigour is strong. The new yellow-fleshed cultivar ‘HFY01’ kiwifruit is a tetraploid, originating from open pollination of female parent JXFX-CK04136. The general fruit shape is ovate, with a weakly depressed stylar end. The average fruit weight is 85 g and maximum fruit weight is 120 g. The flesh is deep yellow. The fruit taste is most appealing, with a fruity aroma. The ripe soluble solids content is 17.5% and total sugar content is about 10.82%, total acid (citric acid) content is 1.44% and vitamin C content is high, at 205 mg 100 g^‑1. Storage life is very good, 6-7 months at low temperature (0°C). When removed from store, fruit has a shelf life of 20-30 days at room temperature. Flowering time is about the end of April and the flowering period is about 5-8 days. The harvest time is early December in Sichuan. The cultivar shows strong resistance to the bacterial disease Pseudomonas syringae pv. actinidiae (Psa). Plant growth is strong.
