| Abstract: | With the development of molecular marker technology and QTL mapping, great advances of molecular breeding based on DNA polymorphism were achieved and applications of MAS based on QTL in some crop breeding successfully, which make it possible to select complex trait. In this paper, mainly applications of MAS and target traits QTL cloning based on crop QTL mapping in crop quantitative traits genetic and breeding such as yield, quantity, and drought resistance etc. were reviewed. Factors influenced the efficiency and prospect of molecular breeding were also discussed. |
