Abstract

AEGILOPS TAUSCHII Coss.is a diploid (2n=2x=14, DD) goatgrass species which has contributed the D genome in common wheat. Considerable morphological variation exists in native populations of A. tauschii. Studies of native populations in Aegilops sp. indicate that these species are desirable genetic sources for wheat breeding. The genetic erosion in wheat cultivars has inspired the study of wild relatives. Genetic variations in 28 populations of AEGILOPS TAUSCHII belonged to different provinces (provided by National Plant Gene Bank of Iran), were evaluated in the experimental field of National Plant Gene Bank of Iran, Karaj, during 2004-2005 and then MORPHOLOGICAL TRAITS were measured.In this experiment, coefficients of correlation ,simple statistics, i.e. mean, standard deviation, maximum,minimum, and coefficient of variations for quanitative traits, shanon index for qualitaitive traits, principle component analysis based on 25 MORPHOLOGICAL TRAITS and cluster analysis based on principle components were evaluated.The results indicated from existance of high variation in this populations.For number of seed per spikelet, a high variation and for days to maturity, a low variation were found as quanitative traits.Using of shanon index in qualitative traits, the highest diversity and a low of diversity belonging to brittleness of rachis and texture of seed respectively. A. significant correlation was observed between days to flowering and days to maturity, among length of spike, length of glum and number of spikelet per spike, and among stem color, stem Fuzz and growth habit. The principle component analysis indicated that eight components explains 82.6% of total variation. The cluster analysis divided the populations to three clusters revealed no consistent with their geographical DISTRIBUTIONs.
