Postulation of resistance genes to barley diseases in heterogeneous varieties
Biologia, 2011Resistance to causal agents of diseases is an important varietal characteristic that influences the management practice of crop plants and thus production costs of commodities. At present, almost all European barley varieties possess at least one major gene for resistance to powdery mildew.

AbstractYellow rust caused by Puccinia striiformis is a wheat disease of worldwide importance. The Yr17 resistance gene introgressed from Aegilops ventricosa was effective, in France, against all yellow rust isolates until 1998. The SC‐Y15 marker is one of three molecular markers closely linked to Yr17. In this paper, results obtained are compared with

Postulated Genes for Resistance to Stripe Rust in Selected CIMMYT and Related Wheats
Plant Disease, 1989Infection type data were used to postulate the presence of stripe rust seedling resistance genes in 20 CIMMYT and related bread wheats. Yr3, Yr6, Yr7 and Yr9 were hypothesized to be present in 12 lines, either alone or in combination. The isolates used also indicated the presence of additional unknown seedling resistance genes. Four lines produced only

Postulation of leaf‐rust resistance genes in Czech and Slovak barley cultivars and breeding lines
Plant Breeding, 2000AbstractLeaf‐rust resistance (Rph) genes in 61 Czech and Slovak barley cultivars and 32 breeding lines from registration trials of the Czech Republic were postulated based on their reaction to 12 isolates of Puccinia hordei with different combinations of virulence genes.

Postulation of Leaf Rust Resistance Genes in Selected Soft Red Winter Wheats
Crop Science, 2003Leaf rust, caused by the fungus Puccinia triticina Eriks., is a major disease nearly wherever wheat (Triticum spp.) is grown in the USA. Soft red winter wheat (T. aestivum L.) cultivars with varying degrees of leaf rust resistance are grown in the southern USA. The objective of this study was to characterize the seedling leaf rust resistance present in

POSTULATION AND MAPPING OF SEEDLING STRIPE RUST RESISTANCE GENES IN ETHIOPIAN BREAD WHEAT CULTIVARS
Journal of Plant Pathology, 2012Stripe rust caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most important diseases of wheat worldwide. In Ethiopia, grain yield loss in wheat cultivars ranges from 30 to 69%. The use of resistant cultivars is the most economical and environmentally friendly method of controlling the disease.

Postulation of leaf (brown) rust resistance genes in 70 wheat cultivars grown in the United Kingdom
Euphytica, 2001Multi-pathotype tests on 70 U.K. wheat cultivars permitted postulation of eight known seedling genes for resistance to Puccinia recondita f. sp.tritici either singly or in combinations. The most commonly detected gene was Lr13 (present in approximately 57% of cultivars), followed by Lr26 (22%), Lr37 (20%), Lr10 (17%), Lr17b (LrH) (10%), Lr1 (7%), Lr3a (

Seedlings of 38 wild emmer derivatives, and a total of 53 advanced wheat varieties/lines introduced from the International Maize and Wheat Improvement Centre (CIMMYT) or other sources, Nepalese breeding lines and local cultivars were inoculated with 18 different yellow rust isolates to postulate yellow rust resistance genes (Yr).

Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is an important disease of wheat in cooler and humid geographic regions. It can cause significant yield losses. Three international nurseries, namely, 1st Australian Special Nursery (ASN), 22nd Semi-Arid Wheat Screening Nursery (SAWSN) and 12th High Temperature Wheat Yield Trial (HTWYT),
