本研究围绕粮食、经济、果树、蔬菜、饲草与绿肥、花卉六大类作物,以物种多样性和遗传多样性等为主线,开展了中国农作物及其野生近缘植物多样性研究,取得重大进展。科学界定和系统规范了种质资源概念和范畴,提出了层次结构的理论,查清了中国粮食与农业植物有9631个物种及其分布、特征特性及用途;深入研究了中国农作物种质资源的本底,首次明确了中国农作物总计有528种(类),涉及1339个栽培物种和1930个野生近缘植物物种;优化了农作物种以下农艺性状分类技术指标,阐明了中国农作物地方品种的987个变种、978个变型、1223个农艺性状特异类型的植物学特征、生物学特性及其遗传多样性;得出了中国是禾谷类作物裸粒基因、糯性基因、矮秆基因和育性基因等特异基因的起源中心或重要起源地之一的结论;首次编撰出版了《中国作物及其野生近缘植物》专著6卷,并编撰了《中国粮食与农业植物物种名录》,形成了具有中国特色的作物种质资源学科理论体系。为农作物种质资源的高效利用、保障粮食安全和农业可持续发展奠定了基础。
This study focused on the six major crops of food, economy, fruit trees, vegetables, forage grass, green manure and flowers. Based on the species diversity and genetic diversity, the research on the diversity of crops and their wild relatives in China was made. progress. Scientifically defined and systematically regulated the concept and category of germplasm resources, put forward the theory of hierarchical structure, identified 9631 species of plants of food and agriculture in China and their distribution, characteristics, characteristics and uses; thoroughly studied the germplasm resources of Chinese crops For the first time, China has identified 528 species of crops in China, involving 1339 cultivated species and 1930 wild relatives. The technical indexes for agronomic traits classification under different crop species were optimized, and 987 Chinese cultivars Varieties, 978 varieties and 1223 agronomic trait-specific types of botanical characters, biological characteristics and genetic diversity; obtained China is a cereal crop naked grain gene, waxy genes, dwarf genes and fertility genes The origin of specific genes, or one of the most important origins. For the first time, six volumes of monographs on monographs of Chinese crops and their wild relatives were compiled and compiled, and the Directory of Plant Species of Food and Agriculture of China was compiled and formed with Chinese characteristics Crop germplasm resources theory system. It laid the foundation for the efficient utilization of crop germplasm resources, the protection of food security and the sustainable development of agriculture.
