Two types of biplots to integrate multi‐trial and multi‐trait information for genotype selection

Crop Science, Volume 64, Issue 3, Page 1608-1618, May/June 2024.
Abstract Genotype × environment interaction (GE) and unfavorable associations among breeding objectives are the two key challenges in genotype evaluation and selection. Dealing with GE includes utilizing repeatable GE and accommodating nonrepeatable GE, and analytical tools for both steps have been developed in recent years.

Expressão da resistência parcial à ferrugem da folha da aveia presente na linhagem MN841801, no ambiente do Sul do Brasil Expression of partial resistance to oat crown rust present in the lineage MN841801 submitted to the South Brazilian environment

Ciência Rural, 2009
A ferrugem da folha é a doença mais importante da aveia, podendo comprometer a qualidade e o rendimento de grãos em até 50%. No ambiente do Sul do Brasil, a maioria dos genes de resistência ao patógeno causador da doença tem baixa efetividade, e a ...

Registration of CDL‐111 and CDL‐167 oat germplasm lines with pyramided adult plant crown rust resistance

Journal of Plant Registrations, Volume 18, Issue 2, Page 410-414, May 2024.
Abstract Oat (Avena sativa L.) production worldwide is constrained by crown rust (caused by Puccinia coronata f. sp. avenae), which can cause significant yield losses. The disease is often controlled by spraying fungicides or planting resistant cultivars.

Diversity of oat crown rust (Puccinia coronata f.sp. avenae) isolates detected by virulence and AFLP analyses

Plant Protection Science, 2010
Forty Puccinia coronata f.sp. avenae isolates from several European countries and Israel were tested for virulence to 18 differential oat lines. Amplified Fragment Length Polymorphism (AFLP) analysis was used to evaluate diversity among the studied ...

Genome-Enabled Analysis of Population Dynamics and Virulence-Associated Loci in the Oat Crown Rust Fungus Puccinia coronata f. sp. avenae

Molecular Plant-Microbe Interactions
Puccinia coronata f. sp. avenae (Pca) is an important fungal pathogen causing crown rust that impacts oat production worldwide. Genetic resistance for crop protection against Pca is often overcome by the rapid virulence evolution of the pathogen.

Genetic analysis and dissection of crown rust resistance in diploid Avena [PDF]

, 1999
Disease resistance genes provide an effective way to prevent disease. They confer resistance specificity to a variety of plant pathogens, however, they share conserved mechanisms of pathogen recognition and resistance induction.

Virulence Structure and Diversity of Puccinia coronata f. sp. avenae P. Syd. & Syd. in Poland During 2013 to 2015 [PDF]

Plant Disease, 2019
The crown rust fungus Puccinia coronata f. sp. avenae P. Syd. & Syd. (Pca) attacks cultivated oat and its wild relatives, causing significant losses to the crop worldwide. Although understanding the origin and dynamics of the pathogen’s diversity is critical to developing methods for its control, there are little relevant data on Pca virulence ...

Broad-Spectrum Resistance to Crown Rust, Puccinia coronata f. sp. avenae, in Accessions of the Tetraploid Slender Oat, Avena barbata [PDF]

Plant Disease, 2009
The use of race-specific seedling genes for resistance has been the primary means of controlling crown rust of oat (Puccinia coronata). As resistance genes from hexaploid cultivated oat, Avena sativa and, later, the wild hexaploid animated oat, A. sterilis, were deployed in oat cultivars, corresponding virulence in the crown rust population increased ...

Inheritance of resistance to specific races of crown and stem rust, to Helminthosporium blight, and of certain agronomic characters of oats [PDF]

, 2017
Observed segregation for reaction to stem rust in several oat crosses was on a monohybrid basis except in the cross Sac x Hajira-Joanette where segregation was observed to be on a three-factor basis.
