Abstract:

Mechanization production of maize, especially mechanical harvesting, is an important measure to improve the comprehensive production capacity of maize and increase farmers' income. Maize kernel moisture is the main factor affecting maize machine harvesting, especially kernel harvesting. Based on the published literature, the concept of dehydration rate of maize kernels and the importance of rapid dehydration cultivar breeding were analyzed, and the research advances in germplasm mining, heredity and QTL mapping, and phenotypic selection of fast dehydration traits in maize were summarized. Finally, maize breeding for fast dehydration was prospected from three aspects, including strengthening the research on genetic mechanism of quick dehydration and other harvesting traits of maize, paying attention to the mining and creation of excellent germplasms such as early maturity, lodging resistance, disease resistance and rapid dehydration, and conducting field and indoor phenotypic selection of breeding materials.
