A New Mutation in Wheat Producing Three Pistils in a Floret

A floret carries only one pistil that will develop into one grain after fertilization in normal cultivated common wheat (Triticum aestivum L.) plants. A new cultivated common wheat mutation line ‘Three Pistils’ is described. It carries three pistils in a floret, all with the potential to develop into grains. The floret morphology of this line is reported. Genetic analysis of the three pistils trait was carried out by crossing Three Pistils with the normal common wheat variety Chinese Spring. F2 population segregation analysis revealed that the three pistils trait is controlled by a single dominant gene. This conclusion was confirmed by the backcross test.

“…Genetically conditioned abnormal spike morphologies having additional spikelets per spike and having high heritability are known, and among them are ramified spikes (RS) and four-rowed spikes (FRS). The morphology of these types has been described previously (Coffman 1924;Haugerud and Cantrell 1984;Koric 1978;Pennell and Halloran 1984;Sharman 1967). Each type is known by other synonyms, including branched spike (Sharman 1967) for RS and supernumerary spikelets (Coffman 1924) for FRS.…”

Because the RS and FRS morphologies were distinctively different, it was generally accepted that they were controlled by different genes.…”

The supernumerary spikelet (SS) trait of durum wheat (Triticum turgidum L.), including the four-rowed and ramified spike types, is characterized by an increased number of spikelets per spike. To determine the inheritance of this trait, the tetraploid ramified spike cultivar PI349056 was crossed reciprocally to normal-spike 'Langdon' durum, and the F1 was backcrossed to each parent. The F1, F2, F3, BC1F1, and BC1F2 were classified for SS expression. Additionally, PI349056 was crossed to the 'Langdon' 2D(2A) disomic substitution line to study linkage of SS genes. The SS trait was recessive to normal spike, and both four-rowed spike and ramified spike progeny were observed in the segregating generations. Segregation in F3 and BC1F2 families indicated that SS in PI349056 was quantitatively inherited, controlled by a major recessive gene and numerous minor genes. Normal-spiked plants selected in families homozygous for the major gene indicated that the major gene did not produce SS when the minor genes were absent. Selection of normal-spiked plants in the F3 and F4 of 'Langdon' 2D(2A) disomic substitution/PI349056 indicated that the minor SS genes were not linked to the major gene on chromosome 2A.Key words: Triticum, branched spike, ramified spike, four-rowed spike.

“…In the first case, additional spikelets emerge at a rachis node, but in the second case-an extended rachilla. In order to distinguish these two types from each other, the turgidum type branching was called supernumerary spikelet (Percival 1921;Coffman 1924) and the vavilovii type-branched spike (Sharman 1944;Koric 1966). There is a tendency to combine both types of branching under the term ''supernumerary spikelet'' (Kadkol and Halloran 1987;Peng et al 2004).…”

The new branched spike form of wheat was synthesized from a cross between a complex wheat line 171ACS {[(T. durum Desf. 9 Ae. tauschii Coss.) 9 S. cereale L. ssp. segetale Zhuk.] 9 T. aestivum L. 'Chinese Spring'} (2n = 6x = 42, AABBDD) and durum wheat variety T. durum Desf. 'Bereketli-95' (2n = 4x = 28, AABB). This branched spike form is distinguished significantly from the other branched spike forms known so far. Later on basis of these plants have been developed the branched spike lines. This study was aimed to generate the segregating populations from reciprocal (F 1 -F 3 ) and backcross (BC 1 F 1 -BC 1 F 3 ) crosses between one of such lines-166-Schakheli (2n = 4x = 28, AABB) and tetraploid wheat species (T. polonicum L., T. turanicum Jakubz., T. durum Desf.) for revealing the inheritance character of this branching trait and study meiotic behavior in reciprocal (F 1 , F 2 ) and backcross (BC 1 F 1 ) progenies. Results showed that this trait is controlled by a single recessive gene despite certain irregularity against Mendelian law in F2 generations and does not depend on gene dosage, i.e., number of chromosomes.
