热带牧草种质资源是热带牧草研究和生产的基础。植物经过长期进化和自然选择,产生了植物遗传上的异质性和分布上的广泛性,现代科学研究有可能从中筛选出具有符合人类需要的性状的品系。与温带牧草相比,热带牧草研究开始较晚,对热带牧草种质资源的收集和研究的历史也较短。到目前为止,只有极少数生态型的豆科和禾本科牧草应用于生产上,也就是说,尚有大量的基因资源处于未开发状态。 Tropical forage germplasm resources are the basis for research and production of tropical forages. After long-term evolution and natural selection of plants, resulting in the plant genetic heterogeneity and distribution of the extensive, modern scientific research may be selected from the line with human needs traits. Tropical forages are late to study compared to temperate forages and have a shorter history of collecting and researching tropical forages. So far, only a few ecotypes of legumes and grasses have been used in production, that is to say, a large number of gene resources are still undeveloped.
