“…The MRS trait has been shown to be determined by a single recessive mrs1 gene on chromosome 2DS (Dobrovolskaya et al, 2009). Here, we genetically characterized four bread wheat SS lines, in addition to the mrs1 mutant, that included both induced and spontaneous mutants.…”

“…Accurate genetic maps that included the mrs1 gene (Dobrovolskaya et al, 2009) were used for further synteny-based identification of SS candidate markers using the COS genes available in bread wheat (Quraishi et al, 2009;Pont et al, 2013). The mrs1 locus is flanked by the COS1 (LOCOs07g38530-Bradi1g23970-Sb02g037070), COS2 (LOCOs07g45064), and COS3 (LOCOs07g48200-Bradi1g17680-Sb02g043000) markers ( Fig.…”

“…S1). In tetraploid and hexaploid wheat species, the development of SS is a recessive trait (Pennell and Halloran, 1983;Klindworth et al, 1990b;Dobrovolskaya et al, 2009) and Figure 1. SS phenotypes in bread wheat.…”

“…The involvement of the homoeologous chromosome group 2 in the control of SS has been suggested in both tetraploid and hexaploid wheats (Sears, 1954;Klindworth et al, 1990a;Peng et al, 1998;Laikova et al, 2005;Yang et al, 2005). Genetic loci linked to the SS trait have been located on the chromosome 2AS in hexaploid (qTS2A-1 locus), tetraploid (branched head [bh] gene), and diploid wheats (bh m gene) and on the chromosome 2D in hexaploid bread wheat (Dobrovolskaya et al, 2009;Li et al, 2011;Haque et al, 2012;Amagai et al, 2014).…”

“…The central and upper thirds of the spike generally have only three spikelets per node, similar to the spike architecture of six-rowed barley (Hordeum vulgare) lines (Tanno and Takeda, 2004). The mrs1 gene, on chromosome 2DS, may be the major determinant of the MRS trait in two genetically related bread wheat lines derived from genotypes obtained by chemical mutation (Dobrovolskaya et al, 2008(Dobrovolskaya et al, , 2009). This gene is also known as bh-D1 (Jia et al, 2013), as it is considered to be a mutant allele of the Bh-D1 locus (http://ccg.murdoch.edu.au/cmap/ccg-live).…”

and Central Siberian Botanical Garden, Siberian Branch of the Russian Academy of Sciences, 630090 Novosibirsk, Russia (A.A.K.) Bread wheat (Triticum aestivum) inflorescences, or spikes, are characteristically unbranched and normally bear one spikelet per rachis node. Wheat mutants on which supernumerary spikelets (SSs) develop are particularly useful resources for work towards understanding the genetic mechanisms underlying wheat inflorescence architecture and, ultimately, yield components. Here, we report the characterization of genetically unrelated mutants leading to the identification of the wheat FRIZZY PANICLE (FZP) gene, encoding a member of the APETALA2/Ethylene Response Factor transcription factor family, which drives the SS trait in bread wheat. Structural and functional characterization of the three wheat FZP homoeologous genes (WFZP) revealed that coding mutations of WFZP-D cause the SS phenotype, with the most severe effect when WFZP-D lesions are combined with a frameshift mutation in WFZP-A. We provide WFZPbased resources that may be useful for genetic manipulations with the aim of improving bread wheat yield by increasing grain number.

New QTL alleles for quality-related traits in spring wheat revealed by RIL population derived from supernumerary × non-supernumerary spikelet genotypes

et al. 2015

A population developed from an exotic line with supernumerary spikelets was genetically dissected for eight quality traits, discovering new genes/alleles with potential use in wheat breeding programs. Identifying new QTLs and alleles in exotic germplasm is paramount for further improvement of quality traits in wheat. In the present study, an RIL population developed from a cross of an elite wheat line (WCB414) and an exotic genotype with supernumerary spikelets (SS) was used to identify QTLs and new alleles for eight quality traits. Composite interval mapping for 1,000 kernels weight (TKW), kernel volume weight (KVW), grain protein content (GPC), percent of flour extraction (FE) and four mixograph-related traits identified a total of 69 QTLs including 19 stable QTLs. These QTLs were located on 18 different chromosomes (except 4D, 5D, and 6D). Thirteen of these QTLs explained more than 15% of phenotypic variation (PV) and were considered as major QTLs. In this study, we identified 11 QTLs for TKW (R (2) = 7.2-17.1 %), 10 for KVW (R (2) = 6.7-22.5%), 11 for GPC (R (2) = 4.7-16.9%), 6 for FE (R (2) = 4.8-19%) and 31 for mixograph-related traits (R (2) = 3.2-41.2%). In this population, several previously identified QTLs for SS, nine spike-related and ten agronomic traits were co-located with the quality QTLs, suggesting pleiotropic effects or close linkage among loci. The traits GPC and mixogram-related traits were positively correlated with SS. Indeed, several loci for quality traits were co-located with QTL for SS. The exotic parent contributed positive alleles that increased PV of the traits at 56% of loci demonstrating the suitability of germplasm with SS to improve quality traits in wheat.
