Analysis of wheat and rye semidwarfing gene distribution in spring hexaploid triticale (Triticosecale Wittm.) cultivars and breeding lines

Analysis of wheat and rye semidwarfing gene distribution in spring hexaploid triticale... A collection of spring hexaploid triticale cultivars and promising breeding lines has been examined for the presence of wheat Rht-B1b, Rht-B1e, and Rht8c semidwarfing genes and the rye Hl semidwarfing gene. It was discovered in spring triticale that these semidwarfing genes are represented by only one, the Rht-B1b wheat gene. The presence of this gene is associated with shortening of spring triticale plants by 28 cm on average, which constituted 26% of their initial height. Rht-B1b was found in all of the studied commercial cultivars of spring triticale, which rendered it possible to conclude that plant height reduction is a necessary condition for increasing the competitiveness of this crop culture. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

A collection of spring hexaploid triticale cultivars and promising breeding lines has been examined for the presence of wheat Rht-B1b, Rht-B1e, and Rht8c semidwarfing genes and the rye Hl semidwarfing gene. It was discovered in spring triticale that these semidwarfing genes are represented by only one, the Rht-B1b wheat gene. The presence of this gene is associated with shortening of spring triticale plants by 28 cm on average, which constituted 26% of their initial height. Rht-B1b was found in all of the studied commercial cultivars of spring triticale, which rendered it possible to conclude that plant height reduction is a necessary condition for increasing the competitiveness of this crop culture.
