Abstract
‘StandClear CLP’ (Reg. no. CV-1162, PI 693236) hard red winter (HRW) wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station and exclusively licensed to Loveland Products, Inc., in 2020. StandClear CLP is a two-gene Clearfield, semisolid-stem wheat intended for use with the selective imidazolinone (IMI) herbicide imazamox. StandClear CLP resulted from a cross of MTS0531 to an IMI herbicide tolerant F1 plant from a population segregating for two acetohydroxyacid synthase (AHAS) genes [TaAHAS1D and TaAHAS1B]. Original herbicide tolerance donors were IMI ‘Fidel’ (TX12588*4/FS2, BASF) for allele TaAHAS1D via descended experimental lines MTCL0309 and MTCL0510, and proprietary hard red spring wheat line CDC Teal 11A (BASF Corporation) for allele TaAHAS1B. StandClear CLP was selected as a F6:7 headrow in 2014 following multiple cycles of phenotypic mass selection for IMI herbicide tolerance and stem solidness. StandClear CLP was tested under the experimental number MTCS1601 from 2016 to 2019 in Montana for field performance, herbicide tolerance, and end-use quality. StandClear CLP is a high-yielding, Clearfield HRW wheat cultivar with intermediate stem solidness, moderate host plant resistance to wheat stem sawfly, and acceptable milling and baking quality.
