Abstract:

Abstract: As one of the important forage grass species, white clover (Trifolium repens L.) has been extensively applied in feed industry and ornamental horticulture. However, the poor resistance of the majority of current white clover cultivars to salinity, drought and other abiotic stresses greatly restricts its adaptability for a broader range of soil and climatic conditions. Transgenic engineering is promising an alternative solution for the genetic modification of abiotic stress tolerence of white clover. In this paper, progresses in the research of tissue culture, transformation and genetic improvement of white clover during the past 30 years were reviewed.
