A combination of increased harvest index and increased seed number per plant may improve wheat yield. We found an accession Triticum durum Desf. var. ramosoobscurum Jakubz. “Vetvistokoloskaya” R-107, whose plant height was short and spike was branched. To characterize R-107, we mapped the genes for semi-dwarfism and branched spike. Semi-dwarf gene Rht_R107(More)
The loci for expression of prolonged spikelet rachilla named ‘sham ramification’ in three tetraploid wheat accessions, two accessions of Triticum jakubzineri Udacz. et Schachm. (2n = 4× = 28, genome BBAA) ‘PI 585014’ and ‘R-101-03’ and one sample of Triticum turgidum L. (2n = 4× = 28, genome BBAA) ‘PI 67339’, were mapped by genotyping F2 populations using(More)
The locus responsible for branched spike in a branched spike mutant of Triticum monococcum L. (2n = 2x = 14, AmAm genome) and soft glume in Triticum sinskajae Filat. et Kurkiev (2n = 2x = 14, AmAm genome) were mapped by genotyping F2 populations using microsatellite markers. Phenotypic analysis in the cross T. sinskajae PI 418587/a branched spike mutant(More)
In the wheat (Triticum aestivum L.) inflorescence, spikelets are arranged in two opposite rows on the main axis. Spikelet primordia initiate alternately on opposite sides at angles of 180°. Genotypes exhibiting screwed spike rachis (SCR) have been selected as a gene resource having non-standard spike morphology in wheat. Although the SCR phenotype is a(More)
Different blue-aleurone wheats display major differences in chromosome composition, ranging from disomic chromosome additions, substitutions, single chromosome arm introgressions and chromosome translocation of Thinopyrum ponticum. Anthocyanins are of great importance for human health due to their antioxidant, anti-inflammatory, anti-microbial and(More)
An identikit is a model of a head created for a purpose of identification. Nowadays, the police use mostly 2D portrait identification, which is simple but has limited possibilities. Therefore, 3D head models have started to be used as identikits. In this paper, we propose small improvements of Free-Form Shape Deformation (FFSD) for 3D identikits creation,(More)
Plants with elongated spikelet rachilla (sham ramification) have been found in the progenies of a cross between hexaploid wheat (Triticum aestivum L., 2n = 6x = 42, BBAADD genome) line ‘171ACS’ and durum wheat (T. durum Desf., 2n = 4x = 28, BBAA genome) ‘Bereketli-95’. 171ACS was the carrier of the genes for sham ramification and extra glume. Expression of(More)
