Inheritance of Slow‐Rusting Resistance to Leaf Rust in Wheat
Crop Science, 1992Race‐specific resistance of wheat (Triticum aestivum L. emend. Thell.) to leaf rust (Puccinia recondita f. sp. tritici) is often short‐lived. Slow‐rusting resistance has been reported to be a more durable type of resistance. To exploit the advantages of this durability, genetic analysis of slow rusting is essential.

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

Molecular genetics of leaf rust resistance in wheat and barley
Theoretical and Applied Genetics, 2020The demand for cereal grains as a main source of energy continues to increase due to the rapid increase in world population. The leaf rust diseases of cereals cause significant yield losses, posing challenges for global food security. The deployment of resistance genes has long been considered as the most effective and sustainable way to control cereal

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.

Inheritance of leaf rust and stem rust resistance in 'Roblin' wheat
Genome, 1993The Canadian common wheat (Triticum aestivum L.) cultivar 'Roblin' is resistant to both leaf rust (Puccinia recondita Rob. ex. Desm.) and stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. and E. Henn.). To study the genetics of this resistance, 'Roblin' was crossed with 'Thatcher', a leaf rust susceptible cultivar, and RL6071, a stem rust ...

Molecular mapping of stem and leaf rust resistance in wheat
Theoretical and Applied Genetics, 2005Stem rust caused by Puccinia graminis f. sp. tritici Eriks and Henn and leaf rust caused by Puccinia triticina Rob. ex Desm. are major constraints to wheat production worldwide. In the present study, F(4)-derived SSD population, developed from a cross between Australian cultivars 'Schomburgk' and 'Yarralinka', was used to identify molecular markers ...

Environmental stability of partial resistance in spring wheat to wheat leaf rust
Euphytica, 1989Five spring wheat cultivars differing in partial resistance (PR) to wheat leaf rust were tested at Wageningen (the Netherlands) on a sandy and a clay site, El Batan (CIMMYT, Mexico) and Ponta Grossa (Brazil) over two years. The cultivars were Skalavatis 56, Little Club (both very susceptible), Westphal 12A, Akabozu and BH 1146 (all three with high ...

Field Phenotyping of Wheat Leaf Rust and Stem Rust
The three rust diseases, yellow (stripe) rust, black (stem) rust, and brown (leaf) rust are major challenges to wheat production, causing annual global yield losses of approximately 15 million tons valued at US$ 2.9 billion. Genetic resistance, including race-specific genes (R genes) and adult plant resistance (APR), is the primary control strategy ...Naeela, Qureshi +3 more

Uredospores of wheat leaf rust did not take up or metabolize exogenous supplies of quinate-U-14C, shikimate-U-14C, p-coumarate-α-14C, or ferulate-α-14C. Caffeate-α-14C was converted to an unidentified ether-insoluble component which was recovered from the germination medium.Phenylalanine-U-14C and tyrosine-U-14C were readily taken up by uredospores of

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.
