In tetraploid wheat (genome nomenclature, BBAA), the SS trait is quantitatively inherited, controlled by a single major gene acting in concert with an unknown number of minor genes (Klindworth et al, 1990b;Haque et al, 2012).…”

“…In tetraploid wheat (genome nomenclature, BBAA), the SS trait is quantitatively inherited, controlled by a single major gene acting in concert with an unknown number of minor genes (Klindworth et al, 1990b;Haque et al, 2012). It has been suggested that the SS trait in hexaploid wheat (BBAADD) is determined by either two (Pennell and Halloran, 1983) or three (Koric, 1980) loci. The SS trait in hexaploid wheat has been reported to be a consequence of the absence of a complete chromosome (Swaminathan et al, 1966).…”

FRIZZY PANICLE Drives Supernumerary Spikelets in Bread Wheat

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.

“…Patil (1958) considered that the branching traits of durum wheat might be controlled by single recessive gene. Pennell and Halloran (1983) studied that unstable branching trait of durum wheat lines AU S4531 controlled by two recessive genes. Aybeniz et al (2011) found that the novel branching panicle traits derived from the hybrid of synthesized wheat line 171ACS and hardy wheat were also controlled by the single recessive gene.…”

“…So far Tibetan triple spikelet wheat is the only one of triple spikelet wheat found in the world, which will provide a new valuable gene resource to mine new favorable genes as well as to develop high yield variety of wheat. Currently, most of studies showed that the trait if multiple spikelet (supernumerary spikelet) would be a recessive trait, governed by one or two genes (Yang et al, 2005;Martinek and Bednar, 2001;Peng et al, 1998a;Millet, 1986;Pennell and Halloran 1983;Sharman, 1967). Some of studies found that the multiple spikelet might be dominant or partially dominant trait inheritance controlled by one or two genes (Sun et al, 2009;Sun et al, 2000;Chapman and McNeal, 1971;Dencic, 1988).…”

Tibetan triple-spikelet wheat is a unique common wheat landrace in Tibet region of China, which has special triple spikelet trait with supernumerary spikelets and florets. Molecular mapping the control gene locus conferring on triple spikelet trait and mining the closely linked markers would be facilitate high-yield wheat breeding by marker-assisted selection approach. In this study, TTSW-5 derived lines from Tibetan triple spikelet wheat and two common-spikelet wheat, Jian 3 and Chuanmai 55, were used to construct the F 2 populations for phenotypic analysis and SSR genotyping. Genetic analysis of phenotypic traits showed that triple spikelet trait of Tibetan triple spikelet wheat is controlled by two independent recessive gene loci. One QTL linked to the triple spikelet trait was detected on the chromosome 2A by using F 2 population from TTSW-5/Jian 3 combination and SSR markers, the targeted locus was located within two SSR markers, Xgwm275 and Xgwm122, the genetic distance between two markers is 6.6 cM with LOD value 6.19, which can be explained 33.1% phenotypic variation, The detected locus tentatively named as qTS2A-1. We speculated that qTS2A-1 locus might be one of dominant loci for controlling the triple spikelet trait, Therefore, SSR markers, Xgwm275 and Xgwm122, might be used as assisted selection markers for triple spikelet trait in high-yield breeding program.

The objectives of this study were to induce callus from single immature wheat embryos, produce multiple seedlings from the induced callus, and analyse the somaclonal regenerants for potential grain production in a space garden. Immature wheat, Triticum aestivum L. (cv. PCYT-10), embryos were excised 10 to 12 days post-anthesis and cultured on modified Murashige & Skoog's inorganic salts. Embryos cultured on medium containing kinetin (6-furfurylaminopurine) at 0.5mgl -~ plus 2 or 3mgl -~ dicamba (1-methoxy-3,6-dichlorobenzoic acid) or 0.2mg 1 -~ 2,4-dichlorophenoxyacetic acid produced calli from which 24, 35 and 39% of the explant tissue exhibited regenerants, respectively. The size of flag leaves, plant heights, tillers per plant, spike lengths, awn lengths, and seeds per spike were significantly different in regenerants of two-selfed recurrent generations (SC~, SC2) than in parental controls. However, there were no significant differences in spikelets per spike between the SC: and parental controls. Desirable characteristics that were obtained included longer spikes, more seeds per spike, supernumerary spikelets, and larger flag leaves, variants that should be useful in wheat improvement programs.
