High Transferability of Homoeolog-Specific Markers between Bread Wheat and Newly Synthesized Hexaploid Wheat Lines
Bread wheat (Triticum aestivum, 2n = 6x = 42, AABBDD) has a complex allohexaploid genome, which makes it difficult to differentiate between the homoeologous sequences and assign them to the chromosome A, B, or D subgenomes. The chromosome-based draft genome sequence of the 'Chinese Spring' common wheat cultivar enables the large-scale development of polymerase chain reaction (PCR)-based markers...
متن کاملProduction and First Assessment of Iranian Secondary Tritipyrum Genotypes (ISTG) by GISH and AFLP Markers in Iran and Germany
Background: Non-Iranian Primary Tritipyrum (2n=6x=42, AABBEbEb) set seed after Triticale (2n=6x=42, AABBRR) and Tritordeum (2n=6x=42, AABBHcHc) but, due to a few undesirable agronomic traits, it cannot fulfil the commercial expectations of farming. Objectives: To remove these deficiencies, six hexaploid Tritipyrum lines were crossed with four Iranian bread wheat cultivars which led to the...
متن کاملEfficiency of anchored and non-anchored ISSR markers to estimate genetic diversity among bread wheat cultivars
DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...
متن کاملThe resistance to leaf rust and powdery mildew of recombinant lines of barley (Hordeum vulgare L.) derived from H. vulgare · H. bulbosum crosses
A set of 23 recombinant lines (RLs) of barley (Hordeum vulgare L.) derived from H. vulgare · H. bulbosum L. crosses was inoculated with barley leaf rust (Puccinia hordei) and powdery mildew (Blumeria graminis f.sp. hordei) at the seedling stage to identify their levels and mechanisms of resistance. Eight RLs were studied further in glasshouse and field tests. All three barley parents ( Emir , G...
متن کاملDevelopment and Molecular Cytogenetic Identification of a Novel Wheat–Leymus mollis Lm#7Ns (7D) Disomic Substitution Line with Stripe Rust Resistance
Leymus mollis (2n = 4x = 28, NsNsXmXm) possesses novel and important genes for resistance against multi-fungal diseases. The development of new wheat-L. mollis introgression lines is of great significance for wheat disease resistance breeding. M11003-3-1-15-8, a novel disomic substitution line of common wheat cv. 7182 -L. mollis, developed and selected from the BC1F5 progeny between wheat cv. 7...
