Fig. 1 Phenotypic features of maize mn-Mu kernels
A: the typical self-cross mature ear of F₁ plant; B-C: the comparison of kernel length (B) and kernel width (C) of the wild type (the upper row) and mn-Mu (the lower row) kernels; D: phenotype of the wild type (the left one) and mn-Mu (the right one) kernels; E: the longitudinal-sectional view of of the wild type (left) and mn-Mu (right) kernels; F: the comparison of 100-kernel weight of randomly selected mature wild type and mn-Mu kernels in the segregated ears. Values are means ±SDs. (**: P< 0.01, Student’s t-test). Bar: 1 cm.
