بررسی در توده های دورگ و نسلهای در حال تفکیک گندم نان تحت شرایط شوری خاک

Genetic variation of wheats segregation population in soil salinity stress provided selection best plant salt tolerance. Lower decreasing of biological yield, increasing number, seed per spike, disease resistance specialy leaf and yellow rust were criterion selection that using in segregation populations. In this study 348 segregation population of bread wheats (F2, F3, F4, F5) was conducted under salinity soil with 12-14 ds/m, at 2005-06 in Ahwaz station. 348 populations (No. 94F2, No. 119F3, No. 42F4, and No. 93F5) was screened according criteria selection (plant height, early maturity, resistance to disease, number of tiller, grain/spik) and seed selection (color, size, disease).
