VARIATION OF DROUGHT STRESS INDEX AT WINTER WHEAT CULTIVARS IN CENTRAL PART OF OLTENIA PUBLISHED

Ofelia Nicoleta Boghici, Gabriela Păunescu
Seventy-six wheat cultivars were compared in the field of ADRS Simnic during three years 2005-2007, where 2005 was a year with rainfall conditions and 2007 year with drought conditions. We identified cultivars of various origins with good results concerning the yield in the drought conditions on the base of drought stress index: TOL = stress tolerance; MP = mean productivity; GMP = geometric mean; SSI = stress susceptibity index; STI = stress tolerance index. The wheat cultivars with good results in stress and non-stress conditions were: Romanian cultivars: Alex, Glosa, Romulus, Boema, Delabrad, Crina, Şimnic 30, Rapid and Dor; Hungarian cultivar Martina; German cultivars Exotic and Cubus; French cultivar Aztec; cultivars Orion and Frini. These genotypes may serve as sources of germoplasm for breeding for drought tolerance.
