Abstract
A new and distinct cultivar of Quillaja saponaria Molina plant named ‘DK-QSCB1348’. The new variety reliably provides plants producing triterpenic saponins whose fractional content of X-series saponins is higher 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 middle and upper third of the stem. Leaves are from oval to elliptical and slightly elongated in shape, uniform in size and the leaf blade is plane; the margin of leaves is entire with some indentations, and the leaf apex is retuse. The resistance or susceptibility to diseases have not been assessed in this new variety.
