بررسی و انتخاب در توده ها و نسل های در حال تفکیک در گندم نان و آزمایش مقایسه عملکرد مقدماتی

In this study ,94 F2 populations which had been received from karaj and 620 F3,F4,F5,F6,F7 and F8 were evaluated under space planting and Mist irrigation conditions. During growing stages, each plant of population and generations were evaluated and the plants of each generation with best agronomic characters, stress tolerant and diseases resistance were selected. The selected plants based on Modified bulk pedigree method were evaluated and the seed selection for each plant were also used. At finally the 49 F2, 42, F3, 37 single plants from F4, 19 single plants from F5, 39 single plants from F6 and 4 single plant from F7 were selected for evaluating in F3, F4, F5, F6, F7 and F8 of next year respectively. Although, 60 wheat pure line obtained from F6 to F8 with desirable agronomic characters and disease resistance were selected to evaluating in priliminary yield trial of Ardabil Agricultural research station. with seventy six pure lines obtained from segregating generations were evaluated as an observation yield trial with two checks (C-79-16 and Gaspard), so twenty seven of them were selected for more evaluating in advance yield trials of next year.
