Abstract

Since a vast section of Iran is located in arid and semiarid region, identification of resistant genotypes to drought, is of paramount importance in reducing the damages that this restriction factor can bring about. So in order to find out the resistance of different genotypes, we need tools, such as RESISTANCE INDEXes, Biplot and THREE-DIMENSIONAL CHARTs that can help us in this regard. In this research program which was carried out in Miandoab Agricultural Research Station, the effects of DROUGHT STRESS on 8 SUNFLOWER genotypes were investigated. The stress was exerted on the plants in two different: stages of flowering and seed formation. A Split Plot experiment was conducted in a randomized complete block design. Main plots included 3 levels of irrigation: 1-normal irrigation. 2-stoping irrigation cut at flowering, and 3-stopping irrigation cut at seed formation slage. Eight different genotypes were allocated to sub-plots. In order to evaluate either resistance or tolerance to drought, six indexes were assessed, that consisted of: Stress-Susceptibility Index (SSI), Mean- Productivity(MP), Geometric-Mean Productivity (GMP), Tolerance(TOL), Stress-Tolerance Index(STI), and Drought-Response Index (DRI).In order to identify better indexes they were concluded on the basis of Biplot and THREE-DIMENSIONAL CHARTs, and also their correlation with seed yield. The better index (es) for stress at flowering stage was MP and for stress on seed formation were GMP, STI and MP. Finally using the obtained information of THREE-DIMENSIONAL CHARTs, the better indexes lead to the selection of Golshid and TPK25630 cultivars for stress resistance at both flowering and seed formatting stages.
