Marcona-type kernel almond with paper shell and associated high proportion of kernel-to-nut crack-out. Origin: University of California, Davis, by T. Gradziel, M. Thorpe, and D. Kester. SB3,54-39E [(Lukens Honey peach × Mission almond) × Nonpareil] × Sel 25-26 almond.; selected 1994; tested as SB13,36-52; introd. 2007. USPP . Nut: similar to Marcona in shape, size; well-sealed paper shell; readily blanched; high oleic acid content; high roasting quality; long storage potential; low proportion of double kernels. Tree: upright-spreading; moderate vigor; nut production on spurs and terminal shoots; partially self-compatible and cross-compatible with all major commercial cultivars; blooms just after Nonpareil and harvests 10–14 d after Nonpareil.
