The heterosis and difference between positive hybrid and reciprocals hybrid of main morphology characters and fibrovascular Bundles Characters was discussed in this paper.The results showed: the heterosis of hybridization between different varieties was various, some characters were positive superiorrity, some were negative superiority.The difference between positive hybrid and reciprocals hybrid of different characters was various, some obvious and some were not obvious.The heterosis was properly used according to different varieties and hybridization tape in the breeding process.
