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 ...

Partial resistance to wheat leaf rust in 18 spring wheat cultivars
Euphytica, 1989Eighteen 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.

Inheritance of Leaf Rust Resistance in Durum Wheat
Crop Science, 1990The 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 ...

Insights of Lr28 mediated wheat leaf rust resistance: Transcriptomic approach
Gene, 2017Leaf rust is a fungal disease that causes severe yield losses in wheat. Resistant varieties with major and quantitative resistance genes are the most effective method to control the disease. However, the main problem is inadequate information for understanding resistance mechanism and its usefulness.

[Early diagnosis of wheat stripe rust and wheat leaf rust using near infrared spectroscopy].
Guang pu xue yu guang pu fen xi = Guang pu, 2015In the present study, near-infrared reflectance spectroscopy (NIRS) technology was applied to implement early diagnosis of two kinds of wheat rusts, i. e. wheat stripe rust and wheat leaf rust, by detecting wheat leaves as disease symptom has not appeared.

Screening diverse wheat genotypes for leaf rust resistance
Genetic Resources and Crop EvolutionWheat leaf rust (caused by Puccinia triticina Eriks.) stands as a significant biotic constraint in commercial wheat production, posing a threat to the sustainable cultivation of both bread and durum wheat. Managing this pathogen through resistance mechanisms is crucial for ensuring robust wheat production.

Pyramiding Strategy for Durable Resistance to Wheat Leaf Rust Pathogen
2001Leaf rust caused by Puccinia recondita Rob. ex Desm. F. sp. tritici Eriks. & Henn is one of the most important diseases in wheat worldwide. The cultivation of resistant wheat is the most economical and environmental by sound method to reduce the yield losses. More than 40 genes for resistance against wheat leaf rust (Lr genes) have been described.

Generally, two strategies are used to control leaf rust disease: i) incorporating genetic resistance into new cultivars ii) the use of fungicides. The first approach is the most environmentally and economically friendly. In this sense deployment through marker assisted selection is preferred, with seedling resistance and adult plant resistance testing.

Characterization of Wheat Leaf Rust Epidemics in Louisiana
Phytopathology, 1990(...) The average apparent infection rates of the epidemics were significantly different for different dates of inoculation. (...) Leaf rust severity was highly correlated with cumulative degree days following inoculation. (...) The logistic model adequately explained the development of leaf rust in time and space.
