Abstract:

Maize is one of the most important grain crops in the world. Improving the kernel quality of maize is a highly concerned problem in the field of maize breeding worldwide. The traditional and conventional breeding methods have the limitations of long breeding time and low transformation rate, so the most economical and effective way to solve this problem is to use molecular marker assisted selection breeding. In order to provide reference for molecular design and breeding of maize quality traits in the future, this study summarized relevant research progress of QTL mapping, molecular marker assisted improvement, candidate gene cloning and transgenic technology application of maize kernel quality traits at home and abroad. Based on the review, the study points out that the utilization of high-quality gene resources in maize is not sufficient, and the application of existing molecular marker technology in maize breeding is not extensive enough. In the future, breeding methods and quality identification techniques should be improved to shorten the breeding cycle of maize.
