GrainGenes Gene Class Report: Difenzoquat insensitivity

[Submit comment/correction]

Gene Class	Difenzoquat insensitivity
Reference	Busch R et al. (1989) Inheritance of tolerance to, and agronomic effects of, difenzoquet herbicide in spring wheat. Crop Science 29:47-50. Snape JW et al. (1987) The chromosomal locations of genes conferring differential response to the wild oat herbicide, difenzoquat. Journal of Agricultural Science Cambridge 108:543-548.
Abbreviation	Dfq
Character affected	Herbicide response
Gene	Dfq1 (Triticum)
Allele	Dfq1 (Triticum) dfq1 (Triticum)
Locus	Dfq1
Comment	Busch et al. (121) reported a single dominant gene for tolerance of Era and Marshall compared with the susceptibility of Eureka and Waldren, but its relationship to Dfq1 is unknown. Insensitivity/resistance is dominant (1003).
