Plant material
Pistachio interspecific hybrid rootstocks consisted of 768 seedlings
derived from a single cross of P. atlantica X P. integerrimaprovided by Foundation Plant Services (Davis, CA) and were sequenced in
2 Illumina HiSeq SR100 lanes at the UC Davis Genome Center. Walnut
interspecific hybrid rootstocks consisted of 228 clones derived from
three crosses (J. microcarpa individuals 31.01, 31.09. and 29.11
crossed with pollen from J. regia cv “Serr”) (Ramasamy et al.,
2021) and were sequenced in a single Illumina NextSeqHigh 75 lane.
