In order to create compact waxy corn germplasms, Zheng58 (a compact common maize inbred line) and Tong759 (a expanded waxy maize line) were used as donor and recurrent parent, respectively. The favorable alleles of major QTL (qLA5) for leaf angle were transferred by backcross with seletion for leaf angle combined marker-assisted selection and 29 plants for BC2F2 were created. Through the background selection of 48 markers and the comprehensive identification of 18 traits such as plant type, stress resistance, yield and quality under high density, 4 new waxy germplasms with compact plant type, high yield, strong stress resistance and good quality were screened out. The average genomic content of the recurrent parent in 4 new germplasms increased from 78.48% to 88.67%, which can be used as parent materials for compact waxy maize breeding. The results of this study provide theoretical references for the improvement of waxy maize germplasms by using common maize and the breeding of new compact and high quality fresh eating waxy maize varieties.

Key words: waxy maize, molecular marker, leaf angle, compact germplasm
