بررسی و انتخاب در نسلهای در حال تفرق گندم نان

Tolerance to disease,resistance to lodging and sprouting and selection for suitable morphological traits have important role in yield increasing. The characteristics of plant that cause yield increase in specific environments area are not canstant and they vary based on environmental conditions. Ma7..andaran province is prone to biotic stresses condition. Genetic materials of this study including 88 F3 generations, 1 18 F4 populations and also 36 lines of preliminary wheat screen nursery were evaluated and selected for suitable traits. Each genotype of the specific number (mass) was harvested individualy and evaluated based on of seed form (based on pedigree method) and then the seeds of suitable plants were mixed (based on combined Pedigree method). After drawing the histogram relate-d the lines ofpeliminary wheat screening nursery, Some wheat lines were tolerant to disease which selected for peliminary regional wheat yield trial (PR WYT). Among these varried collection, 80, 108 and 28 lines of F3,F4 generations and PWSN respectivly were selected to be analyscd in next generations. Keywords: Segregation, Bread Wheat, pedigree, Bulk
