ABSTRACT: The evolution in virulence of Puccinia coronata f. sp. avenae has challenged the genetic resistance to crown rust oat genotypes. New sources are constantly required for yield stabilization and costs reduction. This study aimed characterize genotypes disease´s productive economic impact. Experiments were conducted two environments, with without chemical control. Resistance was measured...

buffering capacity, that is, its ability to adapt to variable weather, insect, disease, weed, and soil conditions. Ways Genetic diversity in cropping systems can provide buffering against to improve a crop’s buffering capacity include intravarying environmental conditions. Therefore, cultivar blends may have greater and more stable yields than their pure-line components. population interplant b...

Selection for oat cultivars with lower lipase activity may be important for other purposes. Lipase may have Oat (Avena sativa L.) is a potentially economically viable source a role in the initiation of oxidative rancidity by some of lipase, an enzyme used in foods, chemicals, and pharmaceuticals, which occurs on the surface of oat caryopses (groats). The objectives lipoxygenases that cause off-...

<p>The resistance in seedling and adult plant of 13 varieties 37 lines oats against stem rust caused by <em>Puccinia graminis</em> f. sp. <em>avenae</em> was evaluated. TNQ TFQ races isolates AMEX18.21.1.1 AMEX18.18.1.1 for evaluation; isolate plants were used. The Diamante, Menonita, Karma Turquesa resistant to the race, but susceptible AMEX18.18.1.1, other two is...

In order to assessment the effect of micro and macro nutrients on agro physiological traits of oat crop a research was conducted via split plot experiment based on randomized complete block design with three replications at Agricultural Research Station, Faculty of Agriculture, Shahid Chamran University of Ahvaz, along 2013-2014. The main factor included different complex of macro and micro nut...

In order to decrease errors and increase the precision efficacy of crop improvement programmes, quality experimental design is required in addition breeding methods. Present study was carried out ninety-six oat genotypes examine relative efficiency randomized complete block (RCB) alpha lattice (ALD). The effectiveness ALD over RCB determined by complex economic traits such as green forage yield...
