Abstract: Maize ear and kernel transport tissue are essential channels which communicate with stem and transport nutrients into kernel. As the rising demand for food, maize ear as the carrier of high yield and high quality whose morphological structure and physiological function of nutrient transport tissue are taken much attention in breeding research recently. Based on the research in China and foreign counties, this paper enumerated the main study methods of maize ear and kernel nutrients transport tissue, summarized its development of phenotypic characters and function and the relationships between yield. Meanwhile, the research direction of maize ear and kernel nutrients transport tissue were prospected in the background of the development of plant genomics and phenomics.

Key words: maize ear, nutrients transport, phenotype characteristic
