Distribution of crop genetic resources by ecological geography in Lai Chau and Dien Bien provinces

Abstract

Study on the distribution of plant genetic resources plays an important role in the conservation, exploitation and development. In this study, crop genetic resources grown in Lai Chau and Dien Bien provinces were investigated, collected and documented. These genetic resources belong to 23 families, 65 genara and 87 species. Poaceae, Cucurbiraceae, Fabaceae, Solanaceae and Zingiberaceae are five familieswith the hightest number of genera, species an germplasms, and the number of accessions of each family is 512, 368, 345, 142, 129, respectively. Rice (Oryza sativa L.) is the most diverse withj 322 accessions, followed by Pumpkin species with 143 accessions (Cucurbiara moschata Duchesne), Maize species (Zea mays L.) with 143 accessions. Locating genetic resources on QGIS software was conducted based on the passport data of collected germplasms, the results produced three maps of those resources distribution with three groups including: Cereal, Vegetable and other crops with complete information and quantity of collected accessions. These maps are crucial for the process of looking up genetic information, conservation management, exploitation and development of genetic resources.
