GrainGenes Gene Class Report: Chlortoluron insensitivity

[Submit comment/correction]

Gene Class	Chlortoluron insensitivity
Reference	Multani DS et al. (1989) Inheritance of isoproturon tolerance in durum wheat transferred from Triticum monococcum. Plant Breeding 102:166-168. Snape J et al. (1988) Differential responses to herbicides in wheat: uses as genetic markers and target genes for genetic manipulation. Proceedings of the International Congress of EUCARPIA: Genetic Manipulation in Plant Breeding, Biotechnology for the Breeder, Helsingar, Denmark.
Abbreviation	Su
Character affected	Herbicide response
Gene	Su1 (Triticum)
Allele	Su1 (Triticum) su1 (Triticum)
Comment	A single dominant gene for tolerance to isoproturon was found in tetraploid wheats derived from a tolerant T. monococcum source (741). This gene is presumably different from Su1. Insensitivity/resistance is dominant (1007).
