“…Interestingly, apples and peaches do not respond the same when 1-MCP, an ethylene blocker, is applied (Cin et al 2006 ) indicating that these systems differ signifi cantly as does their postharvest competence. With apples, various allelic forms of ACO and ACS have been characterized across cultivars, and the allelic states that condition the best fi rmness have been identifi ed with molecular markers opening up the possibility of using these in the selection for better postharvest quality in apple Oraguzie 2010 ;Zhu and Barritt 2008 ) .…”

Fruit breeding is a long-term process which takes a minimum of about a decade from the original cross to a fi nished cultivar. Thus, much thought needs to go into which objectives to be emphasized in the breeding. Although certain objectives, such as yield and basic quality, are always important, the overall lifestyle, environmental, marketing, and production trends affect the objectives that breeders emphasize in their programs as they strive to anticipate the future needs of the fruit industry. The importance of each trend varies with the crop and environment. The major trends are to develop cultivars which simplify orchard practices, have increased resistance to biotic and abiotic stress, extend the adaptation zones of the crop, create new fruit types, create fruit cultivars with enhanced health benefi ts, and provide consistently high quality. Keywords IntroductionFruit breeders need to anticipate cultivar needs at least 10 years into the future, as this is the minimum time that most fruit cultivars take to develop from pollination to release. This chapter explores the larger trends in our lives, such as environmental issues, health consciousness, consumer trends in lifestyle, and the expectations and needs of producers to examine how these affect the objectives of our fruit breeding programs. Trends in the Business of Plant BreedingImproved plant protection legislation in the USA, Europe, and throughout the world has stimulated substantial research and the development of new plants for commercial exploitation. This has also tended to shift the breeding into the private sector (Heisey et al. 2001 ;Frey 1996Frey , 1998Traxler 1999 ) . This shift was quicker for the annual large acreage crops, such as corn, where public-generated commercial cultivars in the USA disappeared in the 1940s and the use of publically generated inbred lines ceased in the 1970s. Currently, public corn breeders concentrate more on basic research into corn breeding and genetics (Traxler 1999 ) .In fruit crops, this shift has been slower and dependent on the crop, with those crops with shorter life cycles and larger markets shifting to the private sector more rapidly. Throughout the world, the proportion of peach releases from public programs has decreased from 45% in the 1980s to 34% in the early 1990s (Della Strada et al. 1996 ;Della Strada and Fideghelli 2003 ;Fideghelli et al. 1998 ) . During the last decade in the USA, only ~15% of the peach and nectarine cultivars were released by public institutions. Support for the development of apricots, cherries, and apples is still with public institutions, but this is eroding and the private sector is becoming more involved in the release and Another factor is decreased funding for public breeding programs. In the USA, the public funding dedicated to breeding activities has decreased dramatically since the 1970s as the government shifted from a philosophy of completely funding programs to assisting programs with partial funding (Moore 1993 ;Frey 1996 ;Heisey et al. 2001 ) . Thus, t...

“…While 1-MCP treatment inhibited the deterioration of fruit quality, its effect on the inhibition of internal ethylene contents was mild. 'Kurenainoyume' possesses a homozygous Md-ACS1-2 allele (Igarashi et al, 2011), which produces less ethylene and a firmer fruit than MdACS1-1/2 and MdACS1-1/1 genotypes (Oraguzie et al, 2007;Zhu and Barritt, 2008). This trait may have affected the results of the present study; 1-MCP treatment failed to show dramatic suppression of the internal ethylene production due to the genetic features.…”

Effects of 1-MCP and Pre-harvest Fruit Bagging Treatments on Cold Storability of the Red-fleshed Apple ‘Kurenainoyume’

The evaluation of storability for the type 2 red-fleshed apple 'Kurenainoyume' is essential to expand its consumption for table and processing use, as the cultivation area of this cultivar has extended year by year. There is also little available information whether cold storage affects the skin and flesh coloration of 'Kurenainoyume' (type 2 apples). In the present study, we evaluated the effect of 1-methylcyclopropene (1-MCP) treatment on the storability of bagged and non-bagged fruit for respective table and processing use over 3 years. Furthermore, we determined the maximum storage duration of both bagged and non-bagged fruit with 1-MCP. No change was observed in the soluble solid content during cold storage regardless of 1-MCP and bagging treatments. The malic acid content, flesh firmness, and skin and flesh coloration decreased with longer storage duration, but the decrease in these parameters was alleviated by 1-MCP treatment. Without 1-MCP, the storage duration of both bagged and non-bagged fruit to maintain flesh firmness and coloration at acceptable levels was about 90 days after harvest (DAH). With 1-MCP, bagged fruit for table use could be stored for about 180-210 DAH with no severe decrease in flesh firmness. Non-bagged fruit for processing use could also be stored for the same duration as bagged fruit, but the flesh firmness severely deteriorated. Although cooling treatment during the fruit growing stage improved flesh coloration, we found that cold storage did not promote this factor.

“…The application of MAS to apple-breeding programs has mainly focused on certain well-known traits of interest, including resistance to scab, flavor, firmness, columnar growth habit, and skin color (Takos et al, 2006;Bus et al, 2007;Zhu and Barritt, 2008;Moriya et al, 2012). For the skin color trait, it has been shown that a RAPD DNA marker derived from the red skin gene, Rf, is able to discriminate between most red and non-red apple cultivars, and has been used in advanced breeding selections (Cheng et al, 1996).…”

ABSTRACT. Pre-selection for fruit skin color at the seedling stage would be highly advantageous, with marker-assisted selection offering a potential method for apple pre-selection. A and MdMYB1 alleles are allele-specific DNA markers that are potentially associated with apple skin color, and co-segregate with the Rf and Rni loci, respectively. Here, we assessed the potential application of these 2 alleles for markerassisted breeding across 30 diverse cultivars and 2 apple seedling progenies. The red skin color phenotype was usually associated with the MdMYB1-1 allele and A 1 allele, respectively, while the 2 molecular markers provided approximately 91% predictability in the 'Fuji' x 'Cripps Pink' and 'Fuji' x 'Gala' progenies. The results obtained from the 30 cultivars and 2 progenies were consistent for the 2 molecular markers. Hence, the results supported that Rf and Rni could be located in a gene cluster, or even correspond to alleles of the same gene. Our results are consistent with the hypothesis that red/yellow dimorphism is controlled by a monogenic system, with the presence of the red anthocyanin pigmentation being dominant. In addition, our results supported that the practical utilization of the 2 function markers to efficiently and accurately select red-skinned apple cultivars in apple scion breeding programs.
