Earliness Per Se by Temperature Interaction on Wheat Development

Differences in time to heading that remain after photoperiod and vernalisation requirements have been saturated are classified as earliness per se ( Eps ) effects. It has been commonly assumed that Eps genes are purely constitutive and independent of environment, although the likely effect of temperature on Eps effects in hexaploid wheat has never been tested. We grew four near isogenic lines (NILs) for the Eps gene located in chromosome 1D (...
