Interpretive Summary: Novel traits discovered within available plant collections are important to plant breeders for the crop improvement. These traits can be used to increase profitability through yield improvement, improving tolerance to biotic or abiotic stresses, plant identity preservation, or genetic studies of associated traits. We developed a line of a new oilseed crop, lesquerella, with a mutant cream colored flower. The normal flower color is yellow, with no known variation before this. This new plant line should benefit researchers looking for visible plant markers to use in breeding, and producers interested in lesquerella for emerging industrial markets

Technical Abstract: A cream flower mutant of lesquerella [Lesquerella fendleri (A.Gray) S. Watson] genetic stock line WCL-CF1 was released jointly by the Agricultural Research Service, U.S. Department of Agriculture, U.S. Water Conservation Laboratory (USWCL), Phoenix, AZ, and the Universidad Autonoma Agraria Antonio Narro at Buenavista (UAAAN), Saltillo, Coahuila, Mexico. This line was derived from an accession collected in Coahuila, Mexico (A4005) on a trip in 1999 funded in part by the USDA, ARS, Office of Germplasm Exchange (Salywon et al., 2005). In their monograph of the genus, Rollins and Shaw (1973) describe the petals of this species as yellow, sometimes with orange guidelines. All plants located at the native collection site had wild type yellow flowers. Flower color for this species is extremely stable and variation for this trait has not been reported to our knowledge. Plants from more than 150 L. fendleri accessions in our working collection and those in the National Plant Germplasm System (NPGS), from throughout the species range, are all yellow flowered.
