This experiment was conducted to evaluate yield potential of 10 common millet(Panicum miliaceum) genotypes using a RCB design with 3 replications in Karaj, Dezful and Gorgan during a 3 year period (2000-2002).Each experimental plot consisted of four rows. Cultural and harvest procedures were those commonly used for common millet yield trails at each location. Data were recorded on traits such as number of tillers per plant , leaf number per plant, stem diametere, days to 50% flowering, panicle length, seed number per panicle, 1000- seed weight, and varietal responses to pests and diseases.Combined analyses of variance were performed for all traits using statistical software of MSTATC.Results indicated that there were significant differences for all traits among genotypes at 0.01 probability level except for number of tillers, days to 50% flowering and forage yield.Mean comparisons showed that gen. 2 with 9.2 leaves, gen. 9 with the stem diameter of 8.45 mm, gen. 10 with panicle length of 35.7 cm, gen. 9 with 1111 seeds per panicle, gen. 9 with 1000- seed weight of 5.16 g, and gen. 3 with the seed yield of 1.859 T/ha had the highest values among the other genotypes. According to the classification of the genotypes based on the mean of traits and considering the lodging and natural shedding percent and responses of each genotype to biotic stresses such as bird damage, The genotypes Kcm2, Kcm7 and Kcm9 were identifies as desirable genotypes for Karaj.The genotypes Kcm5, Kcm8 and Kcm9 were also selected as the best genotypes in Gorgan. The only genotype which was selected in Dezful was the genotype Kcm9. Key words: Common millet, Yield, Final, Encouraging.
