Figure 1. Early embryogenesis and the comparison of suspensor development among SR1, Hamayan and their reciprocal hybrids.
(a) The embryo development from zygote to eight-celled embryo stage in SR1, Hamayan and their hybrids. (b) 32-celled embryos of SR1, hybrid (SR1 × Hamayan), hybrid (Hamayan × SR1) and Hamayan. The frequency of suspensors containing different cell numbers in SR1, hybrid (SR1 × Hamayan), hybrid (Hamayan × SR1) and Hamayan were analyzed respectively (n = 21–26).
