“…Only one variable, ethylene, emerged to explain a significant portion of the model, revealing that disorder incidence declined as IEC at harvest increased. This was reminiscent of the findings of Ehsani-Moghaddam and DeEll (2013) in which a strong negative correlation was found between soft scald and IEC at harvest. DeEll and Ehsani-Moghaddam (2012b) found ethylene to be implicated in the sensitivity of 'Empire' apple fruit to CO 2 -related storage injury.…”

‘Honeycrisp’ apples were found to be sensitive to injury from O2 and CO2 partial pressures typical of those in controlled-atmosphere (CA) storage. A preliminary study was conducted in 2008 to investigate the effect of the following O2/CO2 partial pressure (kPa) combinations: 1/0, 3/0, 1/3, 3/3, 21/3, 21/0 (air), and 21/0 with 1-methylcyclopropene (1-MCP; 1 μL·L−1) on CA-related injuries of 'Honeycrisp' during storage for 6 months at 3 °C. ‘Honeycrisp’ apples were found to be sensitive to an injury comprised of irregular-edged brown lesions in the cortex occasionally accompanied by the formation of lens-shaped voids. The symptoms are similar to CA-related injuries described for other apple cultivars and often characterized as a “CO2 injury.” Injury severity increased as O2 declined and as CO2 increased and was evident within the first month of storage. During 2009, 2010, and 2011, a study was conducted to evaluate options for avoiding injury during CA storage for this cultivar. Fruit were conditioned at 3, 10, and 20 °C for 5 days and then exposed to the following O2/CO2 partial pressure combinations: 3/0, 3/3, 21/0 (regular air); 3/3 with diphenylamine (DPA) drench (1 g·L−1); and 21/0 with 1-MCP (1 μL·L−1). Injury severity declined as the temperature of the prestorage conditioning period increased; holding fruit for 5 days at 20 °C almost completely eliminated the disorder. The antioxidant DPA also provided nearly complete control of CA injury. 1-MCP, although not studied in conjunction with a modified atmosphere, was found to cause no injury in air storage and may provide an alternative to CA storage and avoid the risk of CA injury for ’Honeycrisp’. The relationship between disorder development and growing degree-days, rainfall, and maturity indexes was studied. Ethylene was the only factor with a significant linkage to the development of CA injury (R2 = 0.35; P = 0.0043). Suggestions for handling of ‘Honeycrisp’ for extended storage are presented.

“…The estimation of SBI values with the regression equation, including both fruit quality attributes at harvest and weather conditions during the growing season, is considered adequate with 75% of the predictions that are located in the threshold of ±5% of the observed SBI (RMSE = 4.33, EF = 0.67, and E = -0.48). The main differences from the regression analyses considering only weather conditions on soggy breakdown susceptibility are the implication of fruit firmness at harvest, low temperatures from 31 to 60 DFB, and precipitation from 0 to 30 DFB, with a positive relationship between fruit firmness at harvest and soggy breakdown susceptibility (Ehsani and DeEll, 2013). Firmness varied between 56.9 and 80.2 N over all sites and years of harvest and accounted for only 7% of the variability in SBI.…”

‘Honeycrisp’ is a relatively new apple cultivar highly susceptible to physiological disorders, such as soggy breakdown. The overall objective of this study was to identify preharvest weather parameters that influence the incidence of soggy breakdown over the different phases of fruit development. Using weather data and evaluation of fruit quality from three sites in Ontario, two sites in Quebec, and one site in Nova Scotia from 2009 to 2011, and data from four sites in Ontario from 2002 to 2006, a model for soggy breakdown incidence (SBI) was developed to predict the level of susceptibility in ‘Honeycrisp’ apples. This model uses primarily two weather variables during the last phase of fruit development [91 days from full bloom (DFB) to harvest] to accumulate an SBI index during the growing season, from full bloom to harvest. Cool (temperature <5 °C) and wet conditions (precipitation >0.5 mm) during this last phase resulted in increased soggy breakdown susceptibility levels. The predictions of the SBI model resulted in 68% of well-estimated cases (threshold of ±5%) (RMSE = 6.45, EF = 0.28, E = −0.04). Furthermore, firmness was linked to soggy breakdown, in addition to weather conditions, revealing a positive effect of high firmness at harvest on the development of the disorder. However, the effect of fruit quality attributes (e.g., internal ethylene concentration, starch index, firmness, and soluble solid content) by themselves, without considering weather conditions, revealed no relationship with the incidence of soggy breakdown.

“…This observation was not unexpected, considering how many previous studies evaluating SS and SBD in 'Honeycrisp,' which is considered highly susceptible to both disorders, often observed only small percentage of fruit develop either disorder (Tong et al 2003, DeLong et al 2004, 2006Moran et al 2009Moran et al , 2010DeEll and EhsaniMoghaddam 2010;Ehsani-Moghaddam and DeEll 2013). Some of the discrepancy between observed and expected disorder incidences when considering individual haplotype composition at the identified QTL can be attributed to experimental variation as reflected by non-systematic differences in disorder incidences between 2014 and 2015.…”

Soft scald and soggy breakdown are important postharvest physiological disorders of apple (Malus × domestica). 'Honeycrisp' and some of its offspring are particularly susceptible to developing these disorders. The purpose of this study was to identify molecular markers associated with high incidences of soft scald and soggy breakdown for use in marker-assisted breeding. Towards this aim, we employed a pedigree-based approach using mostly germplasm related to 'Honeycrisp.' Two quantitative trait loci (QTL) were consistently identified on linkage groups (LGs) 2 and 16 across the 2014 and 2015 harvest years. The same QTL were identified for both storage disorders, indicating that they may be physiologically related. 'Honeycrisp' is homozygous for an identical by state haplotype at the LG2 QTL that was consistently associated with a deleterious effect on soft scald and soggy breakdown incidence. This haplotype was traced through SNP-confirmed pedigrees to the following cultivars: 'Grimes Golden,' 'Northern Spy,' 'Rome Beauty,' and 'Fireside' and is common in derived apple germplasm. Haplotypes at the LG16 QTL could not be adequately characterized due to variation between years combined with effects of this QTL being of relatively smaller size and being most evident in individuals that carry two copies of the deleterious haplotype at the LG2 QTL. These results suggest that limiting homozygosity of the deleterious haplotype at the LG2 QTL through marker-assisted breeding would be a valid strategy to limit soft scald and soggy breakdown incidences in apple seedling populations.
