GENETICS OF RESISTANCE TO WHEAT LEAF RUST
Annual Review of Phytopathology, 1996▪ Abstract Leaf rust (caused by Puccinia recondita f. sp. tritici) is the most widespread and regularly occurring rust on wheat. Genetic resistance is the most economical method of reducing yield losses due to leaf rust. To date, 46 leaf rust resistance genes have been designated and mapped in wheat.

Wheat cultivars which have maintained resistance to leaf rust in India for the last 15-20 years carry unknown genes which are expressed at different post-seedling stages or in adult plants. At least 20 such genes have been detected through multi-race tests and tests with defined rust races at high/low temperatures and plants of varying age. These genes

Disease resistance in the genusAegilops L. — stem rust, leaf rust, stripe rust, and powdery mildew
Die Kulturpflanze, 1985Resistance of the GaterslebenAegilops collection was studied in relation to the following wheat diseases: stem rust(Puccinia graminis), leaf rust(Puccinia recondita), stripe rust(Puccinia striiformis) and powdery mildew(Erysiphe graminis). Numerous sources of complete, combined or single resistance have been detected in 487 accessions of 21Aegilops ...

Lr68: a new gene conferring slow rusting resistance to leaf rust in wheat
Theoretical and Applied Genetics, 2012The common wheat cultivar Parula possesses a high level of slow rusting, adult plant resistance (APR) to all three rust diseases of wheat. Previous mapping studies using an Avocet-YrA/Parula recombinant inbred line (RIL) population showed that APR to leaf rust (Puccinia triticina) in Parula is governed by at least three independent slow rusting ...

Stripe rust, leaf rust, and the leaf spot complex are economically important diseases of wheat (Triticum aestivum L.) in western Canada, and genetic host resistance is the most successful management strategy. This study was conducted to identify quantitative trait loci (QTL) associated with these diseases and to provide wheat breeders with sources of ...

Canadian Journal of Research, 1940
A study of the rust reactions of wheat varieties to 20 physiologic races of stem rust has shown that several varieties of the vulgare type, namely, McMurachy, Eureka, and several strains from Kenya, East Africa, are immune in the seedling stage at ordinary greenhouse temperatures (55° F. to 80° F. daily).

Influence of wheat leaf position on leaf rust severity
Euphytica, 1990The relation between flag leaf position and leaf rust severity was investigated in field experiments. Different leaf angles were obtained by attaching ends of flag leaves to strings stretched at different heights along wheat rows. Leaves with angles between lamina and stem of 0° and 45° were significantly less diseased than leaves with horizontal and ...

The Nature and Prevention of Cereal Rusts as Exemplified in the Leaf Rust of Wheat
Nature, 1948"THE most destructive disease of the world‘s greatest food crop", is Dr. K. Starr Chester‘s valuation of Puccinia triticina, the orange leaf rust or brown rust of wheat. The reader who, misled by the short title "The Cereal Rusts", turns to this book for a comparative or systematic account of the cereal rusts will be disappointed.

Triticale diversity in leaf rust resistance
Russian Agricultural Sciences, 2009An evaluation of 416 triticale accessions from the Vavilov All-Russian Research Institute of Plant Industry (VIR) collection reveals a great diversity of forms in the character of leaf rust resistance. A nonuniform distribution of resistant phenotypes is noted in groups differing in ploidy level and geographic origin.

LEAF RUST RESISTANCE OF TRANSEC WHEAT
Canadian Journal of Genetics and Cytology, 1969The same single dominant factor in the wheat-rye translocation line Transec controls resistance to Australian leaf rust strains in the seedling and adult plant stages. Transec did not derive the major factor for adult plant resistance from its Chinese Spring parent. The two factors which are both on chromosome 4A appear to be loosely linked.
