aftab cultivar originated from national cereal breeding programs .the new cultivar  was evaluated in international high rainfall wheat yield trial nursery at gachsaran and gonbad agricultural research stations (2008-2009). due to optimum grain yield and other agronomic traits, the new cultivar was tested in advanced yield trials in gachsaran, ilam, khoram abad and gonbad research stations (2009...

In the Republic of Tatarstan, due to favorable soil-climatic and market conditions, spring wheat production is developed, but grain yields are limited by a number unfavorable factors, one which spread fungal diseases. At same time, pressure pathogenic fungi makes it possible carry out fruitful breeding work in Tatarstan on resistance diseases, main activity Kazan Research Center RAS. The purpos...

More than 50 leaf rust resistance (Lr) genes against the fungal pathogen Puccinia triticina have been identified in the wheat gene pool, and a large number of them have been extensively used in breeding. Of the 50 Lr genes, all are known only from their phenotype and/or map position except for Lr21, which was cloned recently. For many years, the problems of molecular work in the large (1.6 x 10...

Leaf or brown rust is one of the most devastating diseases in wheat. Development and deployment resistance wheat cultivars considered as effective, economic sustainable method protecting against yield losses due to leaf rust. Though several alien genes have been reported utilized, Thinopyron ponticum derived gene Lr24/Sr24 has proved be effective for nearly three decades India. The effectivenes...
