Walnut tissue culture: research and field applications

Abstract

Vitrotech Biotecnologia Vegetal began researching propagating Juglans regia (English walnut) and various Juglans hybrids by tissue culture in 1993 and has operated on a commercial scale since 1996. Since this time, more than one and a half million walnuts of different species have been propagated and field planted. Tissue cultured walnuts on their own roots have proven to be more vigorous and productive than conventionally propagated walnuts. Also, tissue culture is an efficient tool to help breeders select and test possible superior genotypes.
