Genetic 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 کاملResponses 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 کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Virulence 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...
