Big fruit size and nice red pigmentation combined with good flavor should be the major target for red-fleshed kiwifruit (Actinidia spp.) breeding programs. Genetic diversity and plant characteristics were evaluated on a set of kiwifruit accessions with predominantly red flesh to identify the superior individuals for further breeding or study of commercial application. The leading phenotypic cha...

To determine whether ozone can regulate fruit ripening and delay aging, Kiwifruit (Actinidia deliciosa 'Guichang') was fumigated with different concentrations (100 μL/L, 200 300 μL/L) for 3 h, stored at 1 °C 85 ± 5% RH three months, then matured 20 85% 12 days. Compared controls, the optimal concentration of delayed kiwifruit during cold storage by delaying respiratory burst that precedes decay...

Fruits of kiwifruit cultivars (Actinidia chinensis and A. deliciosa) generally have green or yellow flesh when ripe. A small number of genotypes have red flesh but this coloration is usually restricted to the inner pericarp. Three kiwifruit cultivars having red ('Hongyang'), or yellow ('Jinnong-2'), or green ('Hayward') flesh were investigated for their color characteristics and pigment content...

Kiwifruit Vine Decline Syndrome (KVDS) is currently affecting Italian kiwifruit cultivation, causing dramatic yield and economic losses. The syndrome’s aetiology due to soil-borne pathogens waterlogging, leading the decay of roots then canopy. Current knowledge about disease limited, techniques control syndrome are ineffective. use tolerant rootstocks one most promising tools. Six genotypes Act...

Cysteine proteases (CPs) accumulate to high concentration in many fruit, where they are believed to play a role in fungal and insect defense. The fruit of Actinidia species (kiwifruit) exhibit a range of CP activities (e.g. the Actinidia chinensis variety YellowA shows less than 2% of the activity of Actinidia deliciosa variety Hayward). A major quantitative trait locus for CP activity was mapp...
