“…From an economic point of view, two recently published surveys (Rout and Mohapatra 2006;Byrne 2007) of scientific publications and of the activities of ornamental breeding companies regarding the application of molecular marker techniques revealed that, besides SSRs and AFLPs markers, RAPDs remain one of the most commonly applied marker systems in ornamental crops. The study by Rout and Mohapatra (2006) revealed that only a small minority of breeding companies actually use MAS in their breeding process.…”

The establishment of a marker-assisted selection system for the economically important 'budflowering' phenotype in the ornamental crop Calluna vulgaris is of great interest to practical breeding companies, as it would allow selection at the juvenile stage. Segregation analyzes revealed a monogenic recessive inheritance of the bud flowering trait. Since in C. vulgaris only sparse molecular data are available, the search for molecular markers in a segregating backcross progeny was accomplished using PCR techniques based on random primers. Two candidate RAPD markers in coupling of the trait of interest were identified. Results on their applicability in different populations and independent varieties are presented. Their transformation capability to sequence characterized amplified region and single strand conformation polymorphism markers are described and discussed in the context of marker-assisted selection strategies in breeding of ornamental crops.

“…Even though genomics resources are available for a number of perennial crops already, there is evidence that they are underutilized. For example, in a survey of perennial fruit and ornamental breeders, less than half of the breeders used molecular markers in their programs, and those that did performed mostly simple analyses for the purposes of curation (Byrne, 2007). For the large number of genotype–phenotype associations discovered and published by researchers, there appears to be a paucity of markers used in applied breeding programs.…”

Perennial crops represent important fresh and processed food sources worldwide, but advancements in breeding perennials are often impeded due to their very nature. The perennial crops we rely on most for food take several years to reach production maturity and require large spaces to grow, which make breeding new cultivars costly compared with most annual crops. Because breeding perennials is inefficient and expensive, they are often grown in monocultures consisting of small numbers of elite cultivars that are vegetatively propagated for decades or even centuries. This practice puts many perennial crops at risk for calamity since they remain stationary in the face of evolving pest and disease pressures. Although there is tremendous genetic diversity available to them, perennial crop breeders often struggle to generate commercially successful cultivars in a timely and cost-effective manner because of the high costs of breeding. Moreover, consumers often expect the same cultivars to be available indefinitely, and there is often little or no incentive for growers and retailers to take the risk of adopting new cultivars. While genomics studies linking DNA variants to commercially important traits have been performed in diverse perennial crops, the translation of these studies into accelerated breeding of improved cultivars has been limited. Here we explain the "perennial problem" in detail and demonstrate how modern genomics tools can significantly improve the cost effectiveness of breeding perennial crops and thereby prevent crucial food sources from succumbing to the perils of perpetual propagation.

“…The term marker-assisted breeding (MAB) encompasses various uses of markers related to breeding including clone verification and genetic diversity analyses, as well as marker-assisted parent selection (MAPS) and markerassisted seedling selection (MASS). In an international email survey by Byrne [13] over 100 fruit and ornamental breeders were queried about their use of markers in breeding. While 50% reported using markers of some type, the majority was for cultivar identification, measuring genetic diversity, or taxanomic analyses.…”

Applications of molecular markers in strawberry

This review examines current and potential applications of molecular markers in strawberry (Fragaria spp.). The most prevalent uses of markers in strawberry are for analyses of genetic diversity, genetic mapping, and cultivar identification. Cultivar identification is by far the most important use of markers to date for the protection of intellectual property as well as to confirm the identity of nursery stock through multiple cycles of asexual propagation. These applications have been accelerated by continuous discovery of simple sequence repeat markers and the development of multiplexed sets. Mapping studies have confirmed the allopolyploid genome structure of cultivated strawberry and shed light onto genetic events that punctuate its domestication. Though marker-trait associations have been identified for disease resistance, photoperiodic flowering, and sex expression, markerassisted selection in breeding is currently confined to a few entities in the private sector. Pedigree-based analysis holds promise for identifying additional marker-trait associations and simultaneously mining alleles in multiple genetic backgrounds. Meanwhile, the completion of the diploid strawberry genome sequence promises to accelerate candidate-gene approaches for marker discovery.
