Peanut is an important oil and industrial crop, and developing new peanut varieties
with high yield and quality is an important goal of peanut breeding. However, the genetic
basis of cultivated peanut varieties significantly limits the cross-breeding of peanut(Wang et
al., 2013). Mixed high-energy particle fields are a mixture of various particles generated from
the ground-based simulation of cosmic radiation. The use of mixed high-energy particle fields
as physical mutagens is attractive because such fields are easy to produce and control and
generate large biological effects (Liu et al., 2005; Guo et al., 2008).
