Abstract:

Plant height is an important indicator of the ideal plant type of maize and closely related to yield. It affects plant photosynthetic utilization,lodging resistance,harvest index,etc. By altering cell division and elongation,phytohormones change the length and quantity of maize internodes,modifying maize plant height to achieve the effect of dwarfing crops. This paper reviewed the research progress in recent years on the mapping and cloning of QTL/genes that control maize plant height and the formation of dwarf mutants under the regulation of hormones(GA3,IAA,BR),in order to provide references for the production and application of maize breeding.

Key words: Maize, Dwarf gene, Hormone regulation
