Lr68: a new gene conferring slow rusting resistance to leaf rust in wheat

Theoretical and Applied Genetics, 2012
The 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 ...

Influence of wheat leaf position on leaf rust severity

Euphytica, 1990
The 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.

A single NLR gene confers resistance to leaf and stripe rust in wheat

Nature Communications
Nucleotide-binding leucine-rich repeat (NLR) disease resistance genes typically confer resistance against races of a single pathogen. Here, we report that Yr87/Lr85, an NLR gene from Aegilops sharonensis and Aegilops longissima, confers resistance ...

Wheat leaf epicuticular characteristics as rust inhibitors

Journal of Environmental Science and Health, Part B, 1996
Abstract Wheat (Triticum aestivum L.) trichomes influence wheat leaf rust (Puccinia recondita Rob. ex Desm.) germling elongation as a function of the external element (i.e. ‐ Ca, Si, P, CI) concentration. Basal cells of multicellular trichomes have a high Ca content; and, Ca2+ has been shown to inhibit elongation of primary roots.

Inheritance of Leaf Rust Resistance in Durum Wheat

Crop Science, 1990
The inheritance of resistance to leaf rust (Puccinia recondita L. sp. tritici) in durum wheat (Triticum turgidum L.) is poorly understood. Eight leaf rust‐resistant durum cultivars of diverse origin were crossed and backcrossed to a susceptible line, RL6089, to determine the inheritance of resistance and to provide useful information for durum wheat ...

Partial resistance to wheat leaf rust in 18 spring wheat cultivars

Euphytica, 1989
Eighteen spring wheat cultivars were tested in microfields and race nurseries for their partial resistance PR to wheat leaf rust under low and high disease pressure respectively. Large differences existed between the 18 cultivars, Skalavatis 56 being the most susceptible and Ponta Grossa 1 being the most resistant cultivar.

Slow leaf rust development on durum wheat

Canadian Journal of Botany, 1977
Several durum wheat (Triticitm durum) cultivars exhibiting susceptible or moderately susceptible reactions to the leaf rust fungus (Puccinia recondita tritici) were evaluated for slow rusting. Percentage severity and reactions for P. recondita tritici on each cultivar were evaluated periodically after initial infection.

CONTROL OF STEM AND LEAF RUST OF WHEAT WITH FUNGICIDES

Canadian Journal of Plant Science, 1958
The results of field evaluations of fungicides for the control of stem and leaf rust of wheat at Winnipeg are presented. Economical control was achieved by means of chemicals, especially nabam plus zinc sulphate, provided that the rainfall was not adverse during the period of the spray program.
