Responses to Selection for Partial Resistance to Crown Rust in Oat
Crown rust, caused by the fungal pathogen, Puccinia coronata Corda var. avenae W.P. Fraser Ledingham, reduces kernel quality and grain yield in oat (Avena sativa L.). Partial resistance is considered to be a durable form of rust resistance. This study sought to evaluate the feasibility of simultaneously improving partial resistance to crown rust, grain yield, and seed weight in an oat populatio...
متن کاملVirulence of Oat Crown Rust in Brazil and Uruguay
Oat (Avena sativa) is an important forage and grain crop in countries of the southern cone region of South America. Approximately 600,000 ha of oats are grown for grain in Argentina, Uruguay, and southern Brazil. Also, more than 4,000,000 ha are grown for forage (17,19,22), although in Brazil much of the forage oat is A. strigosa rather than A. sativa. In the subtropical to temperate climate of...
متن کاملGenome-Wide Association Mapping of Crown Rust Resistance in Oat Elite Germplasm.
Oat crown rust, caused by f. sp. , is a major constraint to oat ( L.) production in many parts of the world. In this first comprehensive multienvironment genome-wide association map of oat crown rust, we used 2972 single-nucleotide polymorphisms (SNPs) genotyped on 631 oat lines for association mapping of quantitative trait loci (QTL). Seedling reaction to crown rust in these lines was assessed...
متن کاملGenetic Relationships of Crown Rust Resistance, Grain Yield, Test Weight, and Seed Weight in Oat
mained effective in North America longer than 5 yr after the resistance genes were released in pure-line Integrating selection for agronomic performance and quantitative cultivars (Holland, 1997). Monogenic resistances can be resistance to crown rust, caused by Puccinia coronata Corda var. avenae W.P. Fraser & Ledingham, in oat (Avena sativa L.) requires overcome rapidly by new races of the pat...
متن کاملResponse of Iranian Rice Recombinant Inbred Lines (Oryza sativa L.) to Salt Stress in Seedling Stage
Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...
