Abstract

Soil moisture is one of the most important determinants of plant’s seed GERMINATION, emergence and finally YIELD formation in arid and semi-arid zone (e.g. IRAN). In such a situation, the selection of a cultivar resistant to drought is the most important task. In this regard, a research at three levels (Farm, Greenhouse, Laboratorial) was conducted to study 10 genotypes with three improved background including: Improved Indigenous(II) genotypes (Sardary, Roushan, Omid), Improved Indigenous Foreign Crossed (IIFC)(Azadi, Falat, Qods) and four Indigenous lines (IL)(5593/2-3, 6452-6, 5806-3, 7007/2-6). On the basis of our data with decrease of osmotic potential, seed VIGOR with high speed and slope in different genotypes decreased. In -0.8 MPa level of osmotic potential, Omid, Azadi and 5593.2-3 genotypes had the highest and Sardary, 5806-3 and Falat genotypes had lowest seed VIGOR. In -1.6 MPa levels of osmotic potential seed VIGOR of all genotypes severely decreased and in this level of osmotic potential, no significant difference was observed among genotypes. The greater correlation between seed GERMINATION, VIGOR and emergence percentage in farm situation was obtained but the correlation between all GERMINATION characteristics in laboratory and farm situations with YIELD was not significant. Orthogonal analysis shows that II genotypes have greater seed VIGOR in comparison with other groups of genotypes, but did not show any significat difference among the three groups. The percentage and rate of GERMINATION.
