Comment:
According to {10611} the Ppd-B1 allele from Japanese wheats has a stronger effect than the allele from CS.

Comment:
Ppd-A1a was present in 39% of Chinese landraces and 97% of improved cultivars {10622}. GS100 and GS105 had different deletions relative to GS101 and GS104, respectively and both were consistently a few days earlier flowering than their near-isogenic counterparts with Ppd-A1b {10612}

Comment:
Comparative mapping showed that Ppd-D1 was co-linear with barley Ppd-H1 - a member of the pseudo-response regulator (PRR) gene family {10466}.
Jagger amplified the 414 bp band {10466} associated with daylength sensitivity whereas 2174 amplified the 288 bp band associated with insensitivity {10722}.

Comment:
Two genes controlled photoperiod response in T. turgidum {788}. Gene Ppd-H2 on barley chromosome 2HS may be a member of the Ppd-1 orthologous series {766}. QTL : A QTL was detected in chromosome 4BS in Courtot/CS {0132}.
