In Asia, cassava (Manihot esculenta) is cultivated by more than 8 million farmers, driving the rural economy of many countries. The International Center for Tropical Agriculture (CIAT), in partnership with national agricultural research institutes (NARIs), instigated breeding and agronomic research in Asia, 1983. The breeding program has successfully released high-yielding cultivars resulting in an average yield increase from 13.0 t ha-1 in 1996 to 21.3 t ha-1 in 2016, with significant economic benefits. Following the success in increasing yields, cassava breeding has turned its focus to higher-value traits, such as waxy cassava, to reach new market niches. More recently, building resistance to invasive pests and diseases has become a top priority due to the emergent threat of cassava mosaic disease (CMD). The agronomic research involves driving profitability with advanced technologies focusing on better agronomic management practices thereby maintaining sustainable production systems. Remote sensing technologies are being tested for trait discovery and large-scale field evaluation of cassava. In summary, cassava breeding in Asia is driven by a combination of food and market demand with technological innovations to increase the productivity. Further, exploration in the potential of data-driven agriculture is needed to empower researchers and producers for sustainable advancement.
The study was conducted to determine the species composition and distribution characteristics of typical terrestrial plant species for the Truong Sa (Spratly) Islands. By research methods of field investigation reference to documents and expert opinions according to three groups: Typical natural species; Naturalized species and Common natural species has identified 75 species of typical terrestrial plants for the flora of the Truong Sa (Spratly) Islands, 58 genera, 29 families belonging to the Angiospermae, focusing on the Poaceae, Cyperaceae, Malvaceae, Fabaceae, Asteraceae, etc. There’re 7 life forms and 6 habitats were recorded with typical terrestrial plant species distribution. In which, the most concentrated in herbaceous life forms with 49 species (65.3%) and open place land in and around the island habitat with 38 species (50.7%). There are 6 groups of use values identified from typical terrestrial plant species, such as protection, ornamental, medicinal herbs, food, etc. of which the value of protection accounts for 56.0%, with 42/75 species.
Song Thanh Nature Reserve (STNR) is located in Nam Giang and Phuoc Son districts, within Quang Nam province along the Vietnam-Laos border, included 93,249 ha of core zone and 108,398 ha of buffer zone. A total of 831 plant species were recognized in 1997 and 1999 by WWF. This study was implemented intend for building the plant specimen, which was operated in the core and buffer zone of Song Thanh Nature Reserve located in La Dee Commune, Nam Giang District. Total of 71 species, belonging to 40 families were represented in specimens; Fam. Rubiaceae and Fam. Euphorbiaceae are considered as the dominant species; Fokienia hodginsii (Dunn) A. Henry & HH Thomas and Helixanthera annamica Danser to be listed among the endangered species in the Vietnam Red Data Book (2007); 10 species of valuable medicinal plants, 3 species of valuable timber, 2 species of fruit trees.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
