First interspecific multi-parent advanced generation inter-cross (MAGIC) population in <i>Capsicum</i> peppers: development, phenotypic evaluation, genomic analysis, and prospects.

ABSTRACT: This work presents the first eight-way multi-parental advanced generation inter-cross (MAGIC) population in pepper. This interspecific MAGIC population was built with six Capsicum annuum accessions and two C. chinense accessions, selected for encompassing a representative and wide genetic diversity, and being complementary for morphological, agronomic, and fruit quality traits. The population in its third selfing generation has been phenotyped with reliable descriptors and genotyped using genotyping-by-sequencing to assess its overall diversity, homozygosity, parental contributions, and genetic structure. A great variability was found in the phenotyping study, showing many forms of recombination of all the founder lines. Moreover, new phenotypic combinations were found
