Pedigree-Based Analysis in a Multiparental Population of Octoploid Strawberry Reveals QTL Alleles Conferring Resistance to Phytophthora cactorum
Understanding the genetic architecture of traits in breeding programs can be critical for making genetic progress. Important factors include the number of loci controlling a trait, allele frequencies at those loci, and allele effects in breeding germplasm. To this end, multiparental populations offer many advantages for quantitative trait locus (QTL) analyses compared to biparental populations....
متن کاملTransgene transmission frequencies between cultivated strawberry (Fragaria x ananassa Dutch) and other Fragaria species
The transmission of transgenes (uid-A and nptII) was studied in crosses between transgenic plants, with Fragaria x ananassa cultivar Teodora as the donor plant and various Fragaria species as recipient plants. GUS expression and kanamycin resistance were evaluated in embryos and in seedlings after aseptical germination, both in intraand inter-specific crosses as demonstrated by different ploidy...
متن کاملPFRU, a single dominant locus regulates the balance between sexual and asexual plant reproduction in cultivated strawberry.
Strawberry (Fragaria sp.) stands as an interesting model for studying flowering behaviour and its relationship with asexual plant reproduction in polycarpic perennial plants. Strawberry produces both inflorescences and stolons (also called runners), which are lateral stems growing at the soil surface and producing new clone plants. In this study, the flowering and runnering behaviour of two cul...
متن کاملReprogramming of Strawberry (Fragaria vesca) Root Transcriptome in Response to Phytophthora cactorum
Crown rot (Phytophthora cactorum) causes significant economic losses in strawberry production. The best control strategy would be to use resistant cultivars, but polygenically inherited resistance makes the breeding of the garden strawberry (Fragaria × ananassa) challenging. The diploid wild strawberry Fragaria vesca Hawaii 4 genotype was shown previously to have resistance against crown rot. T...
متن کاملDiversity Arrays Technology (DArT) Marker Platforms for Diversity Analysis and Linkage Mapping in a Complex Crop, the Octoploid Cultivated Strawberry (Fragaria × ananassa)
Cultivated strawberry (Fragaria × ananassa) is a genetically complex allo-octoploid crop with 28 pairs of chromosomes (2n = 8x = 56) for which a genome sequence is not yet available. The diploid Fragaria vesca is considered the donor species of one of the octoploid sub-genomes and its available genome sequence can be used as a reference for genomic studies. A wide number of strawberry cultivars...
