*A total number of primary monosomics in Table 1 is 74 that were developed using thermal neutron (10 monosomics) and gamma ray (64 monosomics) treatments. Remaining 18 primary monosomics were developed from desynaptic plants that were shown in Table 2. **From these 74 primary monosomics developed using irradiation, 34 monosomic lines were developed, and this number does not reflect the fertility or transmission ability of primary monosomics.
