This research was conducted at the experimental farm of agriculture faculty unsyiah which began in April 2013 to September 2013. This research used a randomized block design with 6 patterns of non-factorial treatment that G1- wilis genotype, G2- kaba genotype, G3- sinabung genotype, G4- agromulyo genotype, G5- burangrang genotype and G6- anjasmoro genotype with 3 replications in order to obtain 18 units of unit experiment. The parameters measured were the growth of plant height, number of leaves, leaf length and leaf width aged 30, 45, and 60 days after planting and dry weight of plants. Outcome variable measured were the number of pieces cropping, seed number, 100 seed weight, seed weight perhectare, perarea seed weight, seed weight and planting. The resul of this research indicate that there is significant influence between the appearance of the growth and yield of soybean genotypes due to different treatments. Sinabung genotype showed the highest growth and diversity, anjasmoro genotype showed the highest diversity of results. The number of leaves, dry weight, seed weight and weight of 100 seeds perarea have heritability and genetic advances higher. Significant genetic correlation between the characters and yield growth occured in the number of leaves and weight of 100 seeds were negatif. Keywords : Glycine max L.
