Abstrakt: Millets have short growth cycle, and tolerant to drought and salt conditions, so they are good candidate to produce fodder in marginal lands. There are many millet landraces in the country. Development and extension of new varieties and farms or changing in cropping patterns result to extinct local landraces. This study was conducted to collect of millets landraces all over the country. Totally, 140 accessions were collected consisted of 85 accessions of common millet, and 55 accessions of foxtail from 15 provinces. Geographical altitude of the collection sites differed from 820 to 1970 m. Some millet germplasms collected from high salty lands. Statistically, Central tendency and dispersion statistics as well as correlation coefficients were calculated for 25 characteristics of the collection site and 10 seed traits. There were good levels of diversity for seed traits in 2 studied crops. Endosperm texture differed from completely waxy to completely starchy in the 2 species. Pearson correlation coefficients showed there was a positive significant correlation between geographical altitude and grain color (p<0.01, r= 0.583), in the fox tail millets. During this study the Iranian millet genetic resources increased to 90% of the first collection. Since there were high levels of genetic diversity for grain characters, it can be expected for other agro-morphological traits too, that makes the collection suitable for millet breeding.
