Partial resistance of soybean lines to asian rust and white mold

Bioscience Journal, 2018
Soybean Asian rust and white mold stand out to cause great problems to soybean producing regions in Brazil. The aim of this study was to evaluate the partial resistance of soybean lines to Asian rust and white mold.

Nickel-enriched soybean seeds generate plants more resistant to Asian soybean rust [PDF]

Bragantia, 2021
ABSTRACT Asian soybean rust (ASR), triggered by Phakopsora pachyrhizi, can cause great yield losses on soybean and nickel (Ni) has potential to control this disease. This study evaluated the effect of using soybean seeds with different Ni contents on ASR control by performing two experiments.

POTENTIAL DISTRIBUTION ZONES FOR SOYBEAN RUST (Phakopsora pachyrhizi) IN MEXICO

Ecosistemas y Recursos Agropecuarios, 2015
Asian Soybean Rust is one of the most important soybean diseases. Since the past decade, some im- portant soybean production areas in America, like Brazil and the United States of America, have been affected by this disease.

The Arabidopsis non-host defence-associated coumarin scopoletin protects soybean from Asian soybean rust. [PDF]

Plant J, 2019
SummaryThe fungus Phakopsora pachyrhizi (Pp) causes Asian soybean rust (SBR) disease which provokes tremendous losses in global soybean production. Pp is mainly controlled with synthetic fungicides to which the fungus swiftly develops fungicide resistance.

Characterization of three soybean landraces resistant to Asian soybean rust disease [PDF]

Molecular Breeding, 2020
AbstractPhakopsora pachyrhizi is an obligatory biotrophic fungus that causes Asian soybean rust (ASR) disease. ASR control primarily involves chemical control and the use of resistant soybean cultivars carrying an Rpp (resistance to P. pachyrhizi) gene. This study aimed to characterize the ASR resistance of three soybean Asian landraces.

Virulence Diversity of Phakopsora pachyrhizi in Mexico

PhytoFrontiers, 2022
Asian soybean rust, caused by the pathogen Phakopsora pachyrhizi, is the main soybean disease in Mexico and worldwide, threatening its production. Knowledge about the virulence of Mexican rust populations (MRPs) is crucial to develop or introduce soybean

Estimate of soybean defoliation via digital image processing in software [PDF]

Revista Ciência Agronômica, 2022
This study aimed to develop and validate the digital image processing software to quantify leaf coverage, employing the correlation of defoliation values and NDVI with various gradients of defoliation severity of the Asian soybean rust pathosystem.

Relationship between soybean plant defoliation and Asian soybean rust severity [PDF]

Summa Phytopathologica, 2019
ABSTRACT Data from experiments conducted in the field with eight fungicide mixtures added of five mancozeb levels were used to generate gradients of soybean rust severity, plant defoliation, and soybean grain yield. The data were subjected to correlation analysis between defoliation and severity, defoliation and grain yield, and grain yield and rust ...

Partial resistance of different soybean cultivars to asian rust [PDF]

Scientific Electronic Archives, 2020
Soybean crop in Brazil is growing rapidly. In recent harvests, grain production has been record, placing the country in the ranking of the second largest producer of soybeans in the world. Despite increase in production, producers face a major challenge against soybean diseases.

Dissecting Vegetative Period Into Its Phenotypic and Genotypic Components Allows Environment-Specific Breeding in Lentil (Lens culinaris Medik). [PDF]

Physiol Plant
ABSTRACT In legumes, flowering time is regulated by genes responsive to temperature and photoperiod, presenting challenges for high‐latitude lentil producers who must adapt cultivars to short growing seasons and extended daylight hours. Therefore, prolonged vegetative periods are favored in those areas.
