Abstract / Description of output
The ASBP selects and releases varieties for three diverse climatic regions: the subtropical, temperate and Mediterranean environments. A
deliberate consideration in all breeding programs is to maintain genetic diversity within and across sub-programs. Prior to the development of genomic information and access to inexpensive molecular marker technology, genetic diversity in breeding programs was managed through a thorough understanding of the ancestral relationships between breeding lines, known as pedigree information.
In the last decade, two single nucleotide polymorphism (SNP) arrays for strawberries (a 90K (Bassil et al., 2015) and then a 35K (Verma et al., 2017)) have been developed that provide cost effective high-throughput genotyping. The ASBP commenced routine genotyping in 2018 with SNP data now available for ~1000 samples including lines from all three target environments, early and advanced material, released varieties, a few external lines, and seedling material from the powdery mildew screening nursery.
The results from this analysis will help the breeders guard against unnecessary narrowing of the genetic diversity in the breeding pipeline and further leverage the diversity within and across the sub-programs and target environments.
