An illustration of promoting apomixis for hybrid vigor preservation through the CRISPR/Cas9 system. To fix hybrid vigor in F2 scientist are promoting apomixis in hybrid seed to keep intact the characteristics of F1 hybrid seed. The MiMe phenotypes is achieved through disruption of gene-controlling meiosis II which leads toward unreduced embryo sac essential for apomeiosis. However, in other case the hybrid segregate in F2 plant populations and all the important characteristics are lost. 1, Interphase; 2, Prophase-I; 3, Metaphase-I; 4, Anaphase-I; 5, Metaphase-II; 6, Anaphase-II; 7, n gametes; 8, 2 n gametes; NBTs, (new breeding techniques); P/TGMS, Cas9; CRISPR- associated protein 9, tracrRNA (trans-activating RNA).
