Wide hybridization expands the gene pool of cultivated species and can produce genotypes with practical value, often resistant to diseases. In plants, ISSRs are often used for hybrid identification as well as for diversity evaluation. We estimated genetic similarity among advanced genetic stocks of triticale hybrids and identified Aegilops juvenalis introgressions into triticale. Fourteen ISSR primers amplified from 12 to 23 DNA fragments. The number of polymorphic products per primer ranged from three to nine, with a mean of 5.1.

Identification and sequence analysis of grain softness protein in selected wheat, rye and triticale

M. A. S. Kharrazi and Bobojonov, V., Identification and sequence analysis of grain softness protein in selected wheat, rye and triticale, vol. 11, pp. 2578-2584, 2012.

Grain softness protein (GSP) is an important protein for overcoming milling and grain defenses in the innate immunity systems of cereals. The objective of this study was to evaluate and understand GSP sequences in selected wheat, rye and triticale. Using sequences for this gene from a sequence database, we performed clustering analysis to compare the sequences obtained from 3 germplasms with other studied sequences for GSP. The maximum difference between the Hirmand GSP genotype in wheat and the database sequences was 23% in EF109396 and EF109399.

Molecular cytogenetic characterization of a new leaf rolling triticale

E. N. Yang, Yang, Z. J., Zhang, J. F., Zou, Y. C., and Ren, Z. L., Molecular cytogenetic characterization of a new leaf rolling triticale, vol. 10, pp. 2953-2961, 2011.

Leaf rolling occurs in some cereal genotypes in response to drought. We identified and made a phenotypic, cytological and physiological analysis of a leaf-rolling genotype (CMH83) of hexaploid triticale (X Triticosecale Wittmack) that exhibited reduced plant height, rolled and narrow leaves. Gliadin electrophoresis of seed protein showed that CMH83 was genetically stable. Sequential Giemsa-C-banding and genomic in situ hybridization showed that CMH83 contains 12 rye chromosomes; two pairs of these chromosomes have reduced telomeric heterochromatin bands.
