Theoretical and Applied Genetics, 1983
Studies were conducted to determine the influence of the male sterility-inducing cytoplasm of Triticum timopheevii (Zhuk.) Zhuk. on response of several common winter wheat (T. aestivum L.) nuclear genotypes to photoperiod and vernalization. Comparative studies of cytoplasmic substitution lines provide information on the role of the cytoplasmic genetic ...

Identification of the G-genome donor to Triticum timopheevii by DNA:DNA hybridizations
Biochemical Genetics, 1985In vitro DNA:DNA hybridizations and hydroxyapatite thermal-elution chromatography were employed to identify the diploid Triticum species ancestral to the G genome of Triticum timopheevii. Total genomic, unique-sequence, and repeated-sequence fractions of 3H-T.

Tetraploid wheat species Triticum timopheevii and Triticum militinae in common wheat improvement
Acta Agronomica Hungarica, 2002Timopheevii wheats are discussed as donors for improving the disease resistance of common wheat. Attention is paid to the comparison of the morphological and chromosomal characteristics ofTriticum timopheeviiandT. militinae, their crossability withT. aestivumand their response to fungal diseases. The possible origin ofT.

Russian Journal of Genetics, 2018
The database of the world gene pool of wheat was scanned by pedigree and the participation of genetic material from T. timopheevii in the creation of 3088 varieties of common wheat was established. The spatial and temporal dynamics of the propagation of these varieties was studied. Using the analysis of pedigrees, a diversity of T.

Whether the two tetraploid wheat species, the well known Triticum turgidum L. (macaroni wheat, AABB genomes) and the obscure T. timopheevii Zhuk. (A(t)A(t)GG), have monophyletic or diphyletic origin from the same or different diploid species presents an interesting evolutionary problem. Moreover, T. timopheevii and its wild form T.

Heterosis is an important way to improve yield and quality for many crops. Hybrid rice and hybrid maize contributed to enhanced productivity which is essential to supply enough food for the increasing world population. The success of hybrid rice in China has led to a continuous interest in hybrid wheat, even when most research on hybrid wheat has been ...

Starch swelling power and amylose content of triticale and Triticum timopheevii germplasm
Journal of Cereal Science, 2009Abstract Triticale (× Triticosecale Whittmack) and Triticum timopheevii have undergone little selection relative to other grains for quality characters, including starch amylose content. Using starch swelling power (SSP) in water and spectrophotometric analysis of the iodine binding ratio, 247 lines of triticale and 20 lines of T.

Pm37, a new broadly effective powdery mildew resistance gene from Triticum timopheevii
Theoretical and Applied Genetics, 2007Powdery mildew is an important foliar disease in wheat, especially in areas with a cool or maritime climate. A dominant powdery mildew resistance gene transferred to the hexaploid germplasm line NC99BGTAG11 from T. timopheevii subsp. armeniacum was mapped distally on the long arm of chromosome 7A.
