Abstract

A new and distinct cultivar of Quillaja saponaria Molina plant named ‘DK-QSCB1326’. The new variety reliably provides plants producing triterpenic saponins whose fractional content of R-series saponins is lower than 50% on total saponin basis. Plants were obtained by clonal micro-propagation of individuals selected from a population of Quillaja trees grown in an ultra-high-density plantation (app. >20,000 trees/hectare). Clone plants have high vigor after 1-year of growth, producing a large number of lateral branches at the upper third of the stem. Leaves are elliptical in shape, uniform in size and the leaf blade is undulated; the margin of leaves is occasionally dentate, and the leaf apex is retuse. The resistance or susceptibility to diseases have not yet been assessed in this new variety.
