According to the invention, there is provided a novel soybean variety,
designated XB15P03. This invention thus relates to the seeds of soybean
variety XB15P03, to the plants of soybean XB15P03 to plant parts of
soybean variety XB15P03 and to methods for producing a soybean plant
produced by crossing soybean variety XB15P03 with another soybean plant,
using XB15P03 as either the male or the female parent. This 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 varieties or breeding varieties and plant parts derived from
soybean variety XB15P03, to methods for producing other soybean varieties,
lines or plant parts derived from soybean variety XB15P03 and to the
soybean plants, varieties, and their parts derived from use of those
methods. This invention further relates to soybean seeds, plants, and
plant parts produced by crossing the soybean variety XB15P03 with another
soybean variety preferably as part of a breeding program.
