Identification of carriers of Puccinia striiformis resistance genes in the population of recombinant inbred wheat lines
نویسندگان
چکیده
Stripe rust (yellow rust) caused by Puccinia striiformis f. sp. tritici, one of the most dangerous diseases wheat. Marker assisted selection methods make it possible to accelerate resistance gene donors improve breeding material through their introduction into hybridization programs. The goal this study was determine presence/absence yellow genes in wheat recombinant inbred lines Almaly/Avocet (S) and evaluate response Pst. Evaluation seedling Pst allowed us select 2 simultaneously resistant races 111Е231 7E63. Race 7E63 avirulent samples, highly virulent. All studied demonstrated a moderately reaction causative agent at adult plant stage (R-MR). Molecular screening revealed presence marker allele associated with Yr18/Lr34 complex 5 RIL. frequency genotypes inheriting Yr18 22.7%. results can be used MAS programs increase

identification of resistance to puccinia striiformis f. sp. tritici in some elite wheat lines
race-specific resistance of wheat to yellow rust caused by puccinia striiformis f. sp. tritici has been reported as short-lived. partial resistance, a kind of quantitative resistance, has been reported to be more stable. partial resistance in terms of slow rusting parameters including final rust severity (frs), apparent infection rate (r), relative area under disease progress curve (raudpc), an...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Study of Genetic Diversity in Wheat Recombinant Inbred Lines by Factor Analysis
To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...
متن کاملGenetic Diversity and Relationships of Agronomic Characters in Wheat Recombinant Inbred Lines
Objective: Wheat is the most important crop in Iran. Self sufficiency in wheat production is one of the economic and food safety policies in the country. In spite of the efforts which have been made in this area, the mean of wheat yield in Iran is less than its world average. Methods: In order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
