A soybean cultivar designated S040120 is disclosed. The invention relates to
the
seeds of soybean cultivar S040120, to the plants of soybean S040120, to plant parts
of soybean cultivar S040120 and to methods for producing a soybean plant produced
by crossing soybean cultivar S040120 with itself or with another soybean variety.
The invention also relates to methods for producing a soybean plant containing
in its genetic material one or more transgenes and to the transgenic soybean plants
and plant parts produced by those methods. This invention also relates to soybean
cultivars or breeding cultivars and plant parts derived from soybean variety S040120,
to methods for producing other soybean cultivars, lines or plant parts derived
from soybean cultivar S040120 and to the soybean plants, varieties, and their parts
derived from use of those methods. The invention further relates to hybrid soybean
seeds, plants and plant parts produced by crossing the cultivar S040120 with another
soybean cultivar.
