Abstract: Plant seeds are one of the most important organ for  plant propagation, so it directly affects the plants development and the yield and quality of grain. The genetic and molecular mechanisms for the regulation of seed development are complicated and sophisticated, A large number of genes and influence factors genes regulate seed development have been identified. However, the interaction between these genes, how different regulatory pathways form networks to synergistically regulate seed development, and which new genes are involved,  still  need to further study. By sorting out the genes, regulators and regulation patterns involved in seed development, this paper discussed how to use allelic mutation needed by human to improve crop yield and quality, so as to provide theoretical support for plant seed development and genetic improvement of grain yield and quality.

Key words: plant seed development, regulation mechanism, progress
