□ Purpose&Contents
1. Validation of previous GWAS results and their application for MAS
2. Establishment of genomic selection basis for horticultural traits
3. Identification of disease resistant loci using a MAGIC population
4. Gene discovery and molecular marker development for abiotic stress tolerance using comparative genomics

□ Results
1. Marker development for MAS using the previous GWAS results
(1) Molecular markers were developed based on QTL associated with horticultural traits and bacterial wilt resistance identified in the previous study.
(2) Several QTL were identified from an additional GWAS for horticultural traits and heat tolerance in the 2^nd core collection of 162 breeding lines (breeding population).

2. Genomic selection
(1) The breeding population as a training population was used to evaluate the GEBV accuracy of BayesA, Bayesian LASSO and Ridge Regression models, and the best GS model was determined.
(2) GS for horticultural traits was optimized using the most efficient marker set including QTL-based markers from GWAS.
3. Gene discovery and marker development using MAGIC population and comparative genomics methods
(1) The MAGIC population derived from six founders was used to identify novel QTL associated with bacterial wilt resistance.
(2) A gene-based marker associated with salt tolerance was developed based on our previous study and salt/drought tolerance genes were explored.
4. Trait evaluation and cultivar development
(1) Phenotypic variations of target traits were evaluated in field and greenhouse trials.
(2) Combining ability of advanced breeding lines were evaluated and the resulting F1s were tested to develop new cultivars in domestic and international trails.

□ Expected Contribution
1. Core collection and MAGIC population will be a usefual resource for accelerating advanced breeding tool development
2. Novel QTL from GWAS will be utilized for MAS
3. The resulting molecular markers for bacterial wilt resistance can facilitate new cultivar development
4. Accomplishments of this study can lead to advance domestic genomics-based breeding and activate tomato research
5. Breeding lines with abiotic stress tolerance will be useful to develop global leading cultivars
