TRRXU Yellow

TRRXU Yellow is a modern hobby-bred superhot pepper line sold by Matt's Peppers as a selection from Idaho Chile. The live seller note states that the seed for this line was sown in 2023 from seed harvested off 2022 plants, and that a purple off-type appeared in that grow. Idaho Chile traced the most likely pollen source to either WHP 053 or Reaper Purple Peach, both of which are dark-trait chinense lines already circulating in the modern superhot collector scene. That places TRRXU Yellow in the present-day breeder and collector stream rather than among heirloom, landrace, or wild peppers.

The likely parent lines help define the character of the selection. WHP 053 is described as a dark-foliaged pepper with pods that ripen peach-orange with purple mottling, while Reaper Purple Peach is described as an extremely hot Carolina Reaper x Pimenta Puma line with dark purple immature fruit and a mature cream-peach finish with purple striping or mottling. Matt's Peppers also lists TRRXU in several ripe colour selections including yellow, mustard, red, and brown, showing that the line is still segregating by colour and being selected phenotypically. Within that context, TRRXU Yellow stands as the yellow-ripe branch of an unstable superhot chinense hybrid family carrying visible dark-trait influence from the surrounding parent material.

A major factual conflict affects the exact breeding history. Idaho Chile states that the pollen donor was probably WHP 053 or Reaper Purple Peach, but not with certainty, so the precise father is unresolved. That uncertainty changes the exact parentage record, but the live sources still identify TRRXU Yellow as a recent U.S. hobby superhot selection derived from that accidental cross event and preserved as a named yellow phenotype.
