hybrid rice

we reproduced the clonal plants of Fix (Fixation of rice heterozygosity) to T4 generation with 1.9~3.2% clonal seeds rate of Fix-T01th, T12th, T23th and T34th. The descendant clonal plants Fix-T0, T1, T2, T3 and T4 exhibited no discernible differences on plant morphology, clonal seeds rate (3.7~4.3%), genome, methylome and transcriptome. Unexpectedly, few aneuploids were identified in each generation. The visible morphology changes of aneuploids might be caused by chromosome segments elimination. Together, the synthetic apomixis was heritable through multiple generations and few aneuploids were induced when using the synthetic apomixis system.
