The RosBREED Project

PI: Amy Iezzoni, Michigan State University 4 years, Sep 2009 – Aug 2013 Funded by SCRI (USDA-NIFA’s Specialty Crop Research Initiative) $14.4 M ($7.2 M SCRI, $7.2 M in-kind Partners) Collaboration U.S.-wide and international The RosBREED Project

Centered on breeders & breeding programs The RosBREED Project Project Director, Amy Iezzoni -breeder (tart cherry) -geneticist -genomicist -leader
6
The RosBREED Project Mission
7
1)Enhance new cultivar adoption, enlarge market potential, increase consumption = socio-economics knowledge of trait values 2) Establish sustainable infrastructure for MAB in Rosaceae = genome scanning capability, new QTLs (“jewels”) 3) Integrate socio-econ and genomics resources into breeding = pedigree-based breeding information management system 4) Conduct MAB in demo breeding programs, fruit quality focus = MAB implementation 5) Enhance sustainability of cultivar development = tech transfer to more breeders & engage other stakeholders RosBREED’s Objectives
8
QTL discovery (looks promising...) MAB Pipelining (polishing...) Breeding (assembling into masterpieces) “Jewels in the Genome” - discovering, polishing, applying

Trait Values Breeder survey 2010 Producer survey Fall 2011- Winter 2012 Market Intermediary survey Fall 2010- Winter 2011 Household data analysis 2010; consumer survey 2012 What trait is my next breeding target? We like disease resistant apple trees! I like tasty strawberries! We like firm tart cherries that pit well! Processors
14
Socio-Economics Surveys (example for apple) Breeders Market Intermediaries Michigan Producers Washington Producers % of respondents MOST important traits LEAST important traits
15
SNP Genome Scans Illumina Infinium® II SNP arrays: developed 2010, used 2011 9K8K +1K 6K Verde et al. 2012 PLoS One, accepted Chagne et al. 2012 PLoS One 7(2):e31745 Peace et al. manuscript in prep.
16
SNP Genome Scans 9K8K6K 40-60 kb intervals sweet cherry P. avium genome sour cherry SNP 100-200 kb intervals SNP Avg 446 kb/cluster Avg 72% SNPs polymorphic Avg 94% clusters polymorphic RESULTS STRATEGY P. fruticosa genome Avg 27 kb/SNP Avg 84% SNPs polymorphic every 4 th -5 th detected SNP chosen, so spacing varies over genome Avg 38 kb/SNP Avg SNPs polymorphic = 32% (sweet), 36% (sour)

Reference Germplasm CROP REFERENCE SET n=480 BREEDING PEDIGREE SETS
18
Any breeder’s additional germplasm with data Reference Germplasm Minnesota BP Set (n=160) Washington BP Set (n=160) New York BP Set (n=160) CROP REFERENCE SET n=480
19
Standardized Phenotyping Reference Germplasm Sets Public: 480 individuals Additional: +480 individuals Standardized phenotyping at multiple locations, esp. for fruit quality (www.rosbreed.org) Evaluations 2010 & 2011 (2012 next) Available at Genome Database for Rosaceae (www.rosaceae.org/breeders_toolbox)
20
FlexQTL TM for QTLdiscovery, validation, characterization Fruit firmness in apple (HiDRAS data) Pedigree-Based Analysis Flow of a specific linkage block Pedimap for visualizing pedigrees (with alleles, traits, Identity-By-Descent)
21
Jewel Discovery SNP genome scans Standardized phenotypic data Pedigree- Based Analysis QTL discovery

MAB Enablement
23
PBA: crop - wide PBA: breeding program Breeding markers Screening services Marker priorities Crossing scheme Trial MASS Efficient, precise, creative breeding Systematic QTL Validation – The MAB Pipeline Seedling selection scheme supported by RosBREED’s in-development Breeding Information Management System
24
New generations enriched for favorable alleles MAB Successes So Far marker-assisted parent selection marker-assisted seedling selection
25
Two jewels polished in RosBREED, put to routine use in demo breeding programs MAB Successes So Far
26
Routine Use of QTLs in Breeding allele 1 carriers allele 2 carriers Use of QTLs: does not predict definitive differences, but enriches for favorable alleles. Brave breeders! frequency trait level
27
Predicted to be large-fruited (& self-fertile) Thousands of inferior seedlings culled - est. $180K saved! Improved efficiency in seedling evaluation since fall 2010 in RosBREED breeding programs Routine MAB with QTLs (WSU’s apple and sweet cherry breeding programs)
