When breeding the primary spring octoploid triticale derived from crosses of various inbred rye lines to wheat Chinese Spring, the effects of the rye genotype and growth conditions on the plant height and proportion of the first, second, and final (pedicle) internodes to the entire stem length were studied. Two triticale groups were examined: homozygotes for the dominant (Ddw1) and recessive (ddw1) alleles of the gene responsible for short stem in rye. In the short stem triticale lines carrying…

Effects of Rht-B1b and Ddw1 Dwarfing Genes in Two Connecting Populations of Spring Triticale under Greenhouse Experiment Conditions
The studies have demonstrated the negative effect of Ddw1 on spring triticale productivity of the main spike in the greenhouse experiment, which can be partially compensated by Rht-B1b.
TaGRF3-2A Improves Some Agronomically Valuable Traits in Semi-Dwarf Spring Triticale
The results show that, depending on the allelic state, the TaGRF3-2A gene in semi-dwarf spring triticale plants influences the thousand grain weight and the grain weight of the main spike in spring trITicale, which makes it possible to use it to compensate for the negative effects of the dwarfing allele Ddw1.
Genetic Control of Embryo Lethality in Crosses between Common Wheat and Rye
It was found that crosses between common wheat and inbred self-fertile rye lines L2 and 535 gave rise to ungerminating grains, in which the development and differentiation of the hybrid embryo are arrested.
Peterhof collection of rye and its use in genetic studies
The article provides information about the history and methods of development of “Peterhof” rye genetic collection, founded by V.S. Fedorov, and the possibility of using the genetic collection of rye to solve the fundamental problems of plant genetics is discussed.
Characterization of a new T2DS.2DL-?R translocation triticale ZH-1 with multiple resistances to diseases
The new triticale ZH-1, derived from the progeny of common wheat, is immune to both powdery mildew and stripe rust and has stable fertility.
Morphological, Cytogenetic and Molecular Identification of a New Triticale
Fenzhi-1 is a new triticale derived from the wide cross MY11 (Triticum aestivum) × Jingzhou (Secale cereale) after the in vitro rye pollen has been irradiated by He-Ne laser and displays stable fertility and immunity to wheat powdery mildew and stripe rust.
Triticale is modern cereal grain, hybrid of wheat andrye, which inherited the ability of the rye to survive the high frosts, but has a higherprotein value than rye, while higher grain yields and increased tolerance to diseases were inherited from wheat.


Genetic interactions between wheat and rye genomes in triticale
The results suggest that, in general, in triticale allelic interactions within the wheat and the rye components are suppressed in favour of intergenomic interactions.
Influence of wheat and rye parents on agronomic characters in primary hexaploid and octoploid triticale
Estimates of wheat, rye, and wheat×rye interaction variance components disclosed parental main effects to be the most important source of genetic variation in primary triticales.
Genetic interactions between wheat and rye genomes in triticale
A high correlation was found between the frequency of undisturbed pollen mother cells and the frequencyof aneuploids in the subsequent generation and a higher number of aneuPLoids occurred in those populations which were heterozygous for the rye genome.
Primary octoploid triticale have been produced by crossing GA3 sensitive tall wheats with aGA3 insensitive dwarf (ct2)rye as well as a GA3 insensitive dwar (Rht3) wheat with a GA2 sensitive tall rye, and it was suggested that the expression of ct2 is affected by genomic interactions between wheat and rye.

Three varieties, characterised by the possession of varying degrees of resistance to lodging, were grown in a Latin square with a view to determining if any character could be found which would serve
Breeding Strategies for Triticale
The study of agronomic practices for each environment will be important to fully explore triticale's potential, and the type of rye which will give the best genome balance when placed in a wheat background has yet to be established.
