The opportunity to obtain soybean variety with large seed size is very possible, due to the
seed size was determined by the rate of seed growth and duration of dry weight accumulation in
seed fraction, which both were genetically controlled and inherited [9,10,11]. A research by
Krisnawati [12] had successfully obtained soybean large seed size delivered from crossing using
a large seed size parental (>14 g/100 seeds). Cober et al. [13] estimated the heritability for seed
size, obtaining moderate to high values 19-56% for seed size, and concluded that an early
generation selection was effective due to the high heritability of this trait.
