Genomic hybrid breeding is a technology that uses whole-genome markers to predict future hybrids. The breeding companies profit from an improved return of investment due to a built-in plant cultivar protection, which can then be reinvested to breed novel improved varieties (Longin et al., 2012). 2. To breed hybrid seeds, two homozygotic, but as genetically different as possible, parental lines are crossed with each other. A hybrid plant is the result of cross pollinating two different plant varieties and growing the seed the mix produces. Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. Contributors unite from different perspectives and disciplines, ranging from agronomy and hydrology to economics. The resulting collection is an accessible but wide-ranging look at the modern food system. Unlike open-pollinated varieties, when seed saving from hybrid varieties, some will not breed true.
