“…We observed discrepancies between reference annotation genome version 1 and improved version 2, resulting from differences between genome assemblies. Unfortunately, genes have been given different names by Jarvis et al (2017) and Štorchová (2020). Therefore, we provide a side‐by‐side comparison of all genes from both publications in Table S2.…”

“…This study proposed a unified gene nomenclature of FT genes in the Amaranthaceae family species to avoid confusion when comparisons are made between species. Interestingly members of the FTL3 gene family specific for Amaranthaceae species were also identified in quinoa, and their potential role in the adaptation to different environments was hypothesized (Štorchová, 2020). Another genome‐wide survey uncovered 611 sequences with some homology to Arabidopsis flowering time genes and 459 quinoa‐specific flowering genes.…”

Response to photoperiod is of major importance in crop production. It defines the adaptation of plants to local environments. Quinoa is a short-day plant which had been domesticated in the Andeans regions. We wanted to understand the adaptation to long-day conditions by studying orthologues of two major flowering time regulators of Arabidopsis, FLOWERING LOCUS T (FT) and CONSTANS (CO) in quinoa accessions with contrasting photoperiod response. By searching the quinoa reference genome sequence, we identified 24 FT and six CO homologs. CqFT genes displayed remarkably different expression patterns between long-and short-day conditions, whereas the influence of the photoperiod on CqCOL expressions was moderate. Cultivation of 276 quinoa accessions under short-and long-day conditions revealed great differences in photoperiod sensitivity. After sequencing their genomes, we identified large sequence variations in 12 flowering time genes. We found nonrandom distribution of haplotypes across accessions from different geographical origins, highlighting the role of CqFT and CqCOL genes in the adaptation to different day-length conditions. We identified five haplotypes causing early flowering under long days. This study provides assets for quinoa breeding because superior haplotypes can be assembled in a predictive breeding approach to produce well-adapted early flowering lines under long-day photoperiods.

“…Besides, we identified FLOWERING LOCUS T (CqFT2A) within pleio7.1, a QTL found in the F 2 population, exclusively. Although FT genes are described in studies related to flowering time regulation in quinoa and in C. rubrum, no flowering-time function has been specified particularly for the CqFT2A paralog (Patiranage et al 2021;Štorchová 2020). To continue towards identification of candidate genes, we mainly focused on the two pleiotropic QTL detected in F 2 and F 3 populations and identified putative candidate genes based on their known functions in flowering time and yield regulation in other species.…”

Quinoa is a pseudocereal originating from the Andean regions. In spite of quinoa's long cultivation history, genetic analysis of this crop is still in its infancy. We aimed to localize QTL contributing to the phenotypic variation of agronomically important traits. We crossed the Chilean accession PI-614889 and the Peruvian accession CHEN-109, which depicted significant differences in days to flowering, days to maturity, plant height, panicle length, thousand kernel weight (TKW), saponin content, and mildew susceptibility. We observed sizeable phenotypic variation across F2 plants and F3 families grown in the greenhouse and in the field, respectively. We used Skim-seq to genotype the F2 population and constructed a high-density genetic map with 133,923 SNPs. Fifteen QTL were found for ten traits. Two significant QTL, common in F2 and F3 generations, depicted pleiotropy for days to flowering, plant height, and TKW. The pleiotropic QTL harbored several putative candidate genes involved in photoperiod response and flowering time regulation. This study presents the first high-density genetic map of quinoa that incorporates QTL for several important agronomical traits. The pleiotropic loci can facilitate marker assisted selection in quinoa breeding programs.

Quinoa is a pseudocereal originating from the Andean regions. Despite quinoa’s long cultivation history, genetic analysis of this crop is still in its infancy. We aimed to localize quantitative trait loci (QTL) contributing to the phenotypic variation of agronomically important traits. We crossed the Chilean accession PI-614889 and the Peruvian accession CHEN-109, which depicted significant differences in days to flowering, days to maturity, plant height, panicle length, and thousand kernel weight (TKW), saponin content, and mildew susceptibility. We observed sizeable phenotypic variation across F2 plants and F3 families grown in the greenhouse and the field, respectively. We used Skim-seq to genotype the F2 population and constructed a high-density genetic map with 133,923 single nucleotide polymorphism (SNPs). Fifteen QTL were found for ten traits. Two significant QTL, common in F2 and F3 generations, depicted pleiotropy for days to flowering, plant height, and TKW. The pleiotropic QTL harbored several putative candidate genes involved in photoperiod response and flowering time regulation. This study presents the first high-density genetic map of quinoa that incorporates QTL for several important agronomical traits. The pleiotropic loci can facilitate marker-assisted selection in quinoa breeding programs.
