  • a This cross involved transgenic event 29-3. The rest of the crosses involved P1-rr′ plants suppressed by event 29-4.

  • b In this cross, naive P1-rr was used as a female parent and transgenic plant P1-rr′/P1-ww; P1.2b::GUS/– was used as a male parent. All other crosses used naive P1-rr as a male parent.
