摘要
杂种优势利用是玉米种质遗传改良与技术创新的理论基础。利用杂交当代(F0)优势来提高玉米子粒产量和改善品质是研究的重点。综述了近年来玉米杂交当代优势的研究进展,并探讨了杂种当代优势有效利用的主要途径。
Utilization of heterosis is a basis for genetic improvement of germplasm and technical innovation in maize. Recently, studies on the possibility that employing heterosis of Fo to enhance yield and quality of maize have been a focus. In this paper, the advances in heterosis of Fo generation in maize were reviewed during last several decades, and some efficient utilization approaches for heterosis of F0 generation are also discussed.
