Abstract:
At present two separate nomenclature systems exist for wheat and rye. This paper provides a proposed common catalogue of wheat, rye and triticale resistance gene symbols. More than 130 postulated wheat resistance genes are listed. Over 39 rye and 6 triticale resistance (R) genes have been identified and named. Genes responsible for reaction to powdery mildew and to leaf, stem and yellow rusts are the best-represented group of resistance genes. From the common catalogue it can be concluded that there exists a potential for further transfer of rye resistance genes to wheat and triticale. Many molecular markers can be applied for marker-assisted gene transfer, but the expression of the R genes in the new genetic background of triticale remains to be investigated.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
