Abstract Objective: Photoperiod controlling genes (Ppd) are the most important genes
groups that modify early heading in bread wheat. The aim of this research was to evaluate
Ppd genes in Iranian cultivars, and also assessing the effect of Ppd-D1a on earliness trait.
Material and methods: Earliness was transferred from Excalibur to Kalhaydari, Roshan and
Mahdavi cultivars using backcross method to generate BC1F3 generation. Three
photoperiod controlling genes including Ppd-A1, Ppd-B1 and Ppd-D1 were assessed in …
