STUDY OF AGRONOMIC AND IMMUNOLOGICAL TRAITS OF NEW FACULTATIVE AND WINTER WHEAT CULTIVAR SAMPLES

This study presents the research on economically valuable traits of 70 varieties of Facultative and Winter Wheat Observation Nursery for Semiarid Environments (FAWWON-SA) received from the International Wheat and Maize Improvement Center (CIMMYT). The study of agronomic and immunological characteristics of plants under field conditions is of great importance in breeding since it allows a selection of the best genotypes more effectively, identifies and uses the sources of valuable traits and increases the accuracy of breeding. The results showed that 57 cultivar samples were winter-hardy, and the days to maturation ranged from 242 to 247. The mass of 1000 kernel ranged from 45.00 to 97.33 grams being coarse and fulfilled. Under artificial infection background of rusts, 15 cultivar samples were resistant to stem, leaf and yellow rusts. Based on the results, wheat cultivar samples were grouped by agronomic and immunological traits, resulting in the identification of 41 cultivar samples with valuable characteristics which recommended as donors in breeding.
