Reduced Height (Rht) Alleles Affect Wheat Grain Quality
The effects of dwarfing alleles (reduced height, Rht) in near isogenic lines on wheat grain quality are characterised in field experiments and related to effects on crop height, grain yield and GA-sensitivity. Alleles included those that conferred GA-insensitivity (Rht-B1b, Rht-B1c, Rht-D1b, Rht-D1c) as well as those that retained GA-sensitivity (rht(tall), Rht8, Rht8 + Ppd-D1a, Rht12). Full ch...
متن کاملEffect of Reduced Height Genes (Rht) on Components of the Root System in Bread Wheat
It is accepted that there is an interaction between dwarfing genes and the overall size of a plant because of the gene’s interaction with gibberellic acid pathways. The main objective of this project was to determine the effect of four stem dwarfing genes (Rht1, Rht2, Rht3 and rht) on components of the root system in near-isogenic lines of Maringa and Nainari 60. The working hypothesis was that...
متن کاملThe transfer and history of "reduced height genes" (Rht) in wheat from Japan to Europe.
Wheat is the main crop and often a strategic crop in many European countries. From a historical perspective, we describe the transfer of "reduced height genes" (Rht genes) from Japanese wheat varieties to wheat varieties in Europe and their influence on the increase of the total wheat production in the last century. Historic pathways of Rht genes were influenced directly or indirectly by wheat ...
متن کاملInduced Mutations in Bread Wheat (Triticum aestivum L.) CV. ‘Kharchia 65’ for Reduced Plant Height and Improve Grain Quality Traits
Through mutagenesis with gamma rays, mutants characterized by reduced plant height, square head, awnless ear, amber seed colour, bold seeds and storage capacities were induced in bread wheat (Triticum aestivum L) cv. Kharchia 65. The were isolated in M generation; derived from 10, 20, 30 and 40 kR of gamma 2 rays treated M population. In the M generation, some, progenies with morphological muta...
متن کاملتوزیع آللی برخی از ژن های مؤثر در پاکوتاهی ارقام و لاین های گندم (Triticum aestivum L.) ایران
Decrease the plant height using the Rht genes is one of the main strategies to improve the resistance to lodging and fertilization and to increase the productivity in wheat. In Iran, like to other parts of world, these genes are entered to new introduced and released varieties. To study allelic diversity of two main dwarf genes (Rht-D1b and Rht-B1b) and their effects on morphological traits of ...
