“…However, usually the first fruit quality selection step is carried out at the fifth to the seventh year after crossing. Currently, cultivated apples have often no resistance to fungi causing fruit decay as breeders seldom evaluate for resistance to postharvest diseases (Ahmadi-Afzadi et al 2013;Janisiewicz et al 2008;Volk et al 2015).…”

Postharvest diseases of pome fruit are typically caused by a wide diversity of fungal pathogens, and the list of confirmed causal agents is still growing. There is considerable knowledge on the epidemiology of wound pathogens, such as Botrytis cinerea and Penicillium expansum. In contrast, knowledge on the occurrence of the different postharvest diseases caused after latent (quiescent) infections during long-term storage and their epidemiology is limited. Well-known pathogens causing postharvest losses after latent infections are Neofabraea spp. and Colletotrichum spp., but in many cases the causal agents that occur in a specific region remain unknown and their control relies on the routine use of fungicide applications. However, due to the growing concern over the use of synthetic fungicides, alternative control measures are highly desired. Over the past years the use of physical treatments, natural compounds, and biocontrol agents have been investigated as alternatives. However, no single method has emerged that can robustly and reliably control postharvest diseases of pome fruit in practice. In this review it is argued to approach latent postharvest diseases as complex problems that require multiple interventions at different stages of the disease process in a systems intervention approach for their control. Such approach requires a deep understanding of the epidemiology of the causal agents in the orchard, fruit defence mechanisms against pathogens, and the molecular biology of host-pathogen interactions in order to develop novel disease control methods in which the deployment of resistant cultivars can be a cornerstone.

“…Biggs and Miller (2001) observed that disease caused by C. acutatum in different apple cultivars was not influenced by the quality parameters evaluated. In contrast, Ahmadi-Afzadi et al (2013) found that as apple fruit firmness decreases, the penetration and infection is facilitated, which increases the severity of pathogens. In the present study, the lack of correlation between most of fruit quality parameters evaluated and the development of fungus may means that it be caused by other factors, such as constitutive or induced responses, which could determine the fruit's susceptibility beyond the effects of the intrinsic proprieties of the apple (Vilanova et al, 2013;Burón et al, 2014).…”

“…Apple production is based on many commercial cultivars with limited resistance to various diseases and pests, and adaptation to environmental stresses. Resistance against Penicillium expansum, the most destructive postharvest pathogen causing blue mold decay, declines quickly as the fruit matures and there is practically no resistance at harvest (Ahmadi-Afzadi et al, 2013;Vilanova et al, 2014). This pathogen infects apples through wounds, which must be protected against this fungus in order to prevent decay development (Janisiewicz 1999).…”

Several wild apple accessions (Malus sieversii) from Kazakhstan and two (Malus × soulardii, Malus sylvestris) from other parts of the world are highly resistant to blue mold decay caused by Penicillium expansum. Previous studies on the wound responses of these apples to infection by this fungus suggest multiple mechanisms of resistance including innate immunity. In this study, the phenolic composition of extracts from mature wild apples resistant (GMAL 4317.f, PI 589391, and PI 369855) and susceptible (GMAL 3623.i) to blue mold, as well as the susceptible cultivar "Golden Delicious" (Malus × domestica) were investigated using ultra-high-performance liquid chromatography coupled to diode array detection and high resolution multiple stage mass spectrometry (UHPLC/DAD/HRMS). The metabolomic and quantitative results of this study support the hypothesis of the possible relationship between the phenolic content of wild apples and their resistance to P. expansum. Apple accessions resistant to P. expansum had higher concentrations of procyanidins, dihydrochalocone, flavonols, and hydroxycinnamic acids. Findings from this study may lead to development of the physiological markers of resistance that could be used by breeders in evaluating crosses for resistance to blue mold and may be helpful to further define apple defense mechanism(s) against P. expansum.
