2020年我国玉米生物学研究继续保持高速发展态势，创新研究成果不断涌现，我国玉米研究团队在国际顶尖学术期刊发表的文章数量稳步提升。在89个SCI或SCIE期刊上发表玉米生物学研究论文369篇，相对于2019年的366篇略有增加，其中，5年平均影响因子超过5.0的高水平论文有86篇，比2019年的83篇增加了3篇，论文质量稳步提升。369篇论文的研究内容涉及玉米基因组学、玉米株型相关性状遗传调控、玉米子粒发育遗传调控、玉米雌穗和雄穗穗性状遗传调控、玉米抗生物和非生物胁迫遗传调控、玉米养分利用遗传调控和玉米育种技术研究等。本文概括性地综述2020年我国科学家在玉米生物学研究领域取得的代表性研究成果。

Maize biology research in China continued to maintain high-speed progress in 2020, with increasing number of original research articles published in top international journals. At least 369 research papers were published in 89 SCI or SCIE journals, being marginally higher than that of the year 2019(366). Among them, there were 86 papers published in journals of high impact factor(>5.0 in five years), three more than that of the year 2019(63). The overall quality of papers published is increased steadily over the past years. In this review, we summarize the research progresses made in the following areas:genomics of maize, genetic regulations of maize kernel development, genetic regulations of ear and tassel related traits, genetic regulations of maize biotic and abiotic stresses, maize breeding technologies. This review summarizes the representative research achievements of maize biology from research groups in China of the past year.
