Two field experiments were carried out at the Experimental Station, Faculty of Agriculture, MansouraUniversity, Dakhlia Governorate during the two summer seasons of 2006 and 2007. The main objectives of these experiments were identified some morphological of five soybean (Glycine max, L.)varieties i.e. Giza 21 , Giza 22 , Giza 35 , Giza 111 and Crawford, three peanut (Arachis hypogaea, L.) varieties i.e. Giza 4, Giza 5 and Giza 6, three sesame (Sesamum indicm, L.) varieties i.e. Giza 32, Shandwell  3 and  Taka  2  and two sunflower (Helianthus annuus, L.) varieties i.e. Genotype102 and Genotype 53 are used in this experiments. Complete Block Design in four replications was used. 1- The results on soybean varieties indicated that Giza 21 variety was identified by tallest plants, highest number of branches/plant and pod length compared with other verities. Giza 22 variety was characterized with heaviest seed weight. Giza 35 variety was identified by higher in number of internodes/stem, number of leaves/plant, number of days to 50% flowering and number of pods/plant compared with other soybean varieties. Giza 111 variety was characterized with heighest number of seeds/pod, stem diameter and seed length. In addition, Crawford variety was identified by more seed width only compared with other varieties. 2- The results on peanut varieties indicated that Giza 4 variety was identified by tallest plants, more in seed length, leave width, leave length, pod length, highest number of branches/plant, number of days to 50% flowering and heaviest seed weight compared with other studied varieties. In addition, Giza 6 variety characterized with more seed width only compared with other varieties. 3- The results on sesame varieties indicated that Taka  2 variety was identified by more in seed length, seed width, number of days to 50% flowering and Shedding percentage compared with other studied varieties. Giza 32 variety characterized with heaviest seed weight, tallest plants, highest number of branches/plant, number of flowers/ plant, number of capsules/ main stem and number of seeds/ capsule compared with other varieties. In addition, Shandwell 3 variety was identified by mor height of capsule length only compared with other studied varieties. 4- The results on sunflower varieties indicated that Genotype102 variety was identified by tallest seed and more in seed width, leaf shape, number of bracts on the back head, anthocynin coloration of bracts, color of ray flower, disk flower color, number of days to 50% flowering, number of seeds/head, head diameter and heaviest seed weight compared with Genotype53. In addition, Genotype 53 variety characterized with tallest plants, stem diameter, stem harness at the top, number of internodes/stem, internodes length/ stem, number of leaves/plant, leaf hight of the tip of tabled to insertion of petiole, bract shape, number of ray flower and  head attitude (at maturity) only compared with Genotype 102. It could be summarized that morphological identification of Soybean, Peanut, Sesame and Sunflower varieties very important in breeding program of new varieties production for keeping varieties for higher production of these crops per unit area. Key words: Soybean, Peanut, Sesame, Sunflower, Varieties, Identification, Morphological characteristics.
