Genetic Management of Virus Diseases in Peanut uri icon

abstract

  • Peanut, also known as groundnut (Arachis hypogaea L.) is a major oilseed crop inthe world. About 31 viruses representing 14 genera are reported to naturallyinfe.ct peanut in different parts of the world, although only a few of these are ofeconomic importance. These include groundnutrosette disease in Africa, tomatospotted wilt-disease in the United States, peanut bud necrosis disease in southAsia, and peanut stripe virus disease in east and southeast Asia. Cucumbermosaic virus disease in China and Argentina and peanut stem necrosis disease incertain -pockets in southern India are also economically important. Host plantresistance provides the most effective and economic option to manage virusdiseases. However, for many virus diseases, effective resistance gene(s) incultivated peanut have not been identified. With a few exceptions, the virusresistance breeding work has received little attention in peanut improvementprograms. Transgenic resistance offers another option in virus resistancebreeding. This review focuses on the status of genetic resistance to variouseconomically important groundnut viruses and'use of transgenic-technology forthe improvement of virus resistance
