主要从种质资源的鉴定、改良创新及骨干亲本的筛选入手,阐述了农作物杂交育种中亲本优选及组配研究的进展和动向。认为在亲本配组中除了考虑亲本的性状、亲缘关系外,还应选用生态类型和地理起源有差异、配合力高的亲本,结合分子辅助选择技术选育农作物新品种。
Mainly from identification, improvement and innovation of germplasm resources and selection of key parents, the progress and trend of research on parental preference and combination in crop hybridization breeding were expounded. It is considered that in addition to considering the traits and kinship of the parents, the parents of the parents should also select the new varieties of crops with ecological type and geographical origin that have different origin, high combining ability, and molecular aided selection techniques.
