“…Collections-Prior to collecting trips a database was generated from locality data in Rollins and Shaw (1973) and from accessions in several herbaria including Universidad Autónoma Agraria Antonio Narro, Mexico (ANSM), Arizona State University (ASU), Brigham Young University (BRY), University of Colorado at Boulder (COLO), Gray Herbarium (GH), Missouri Botanical Garden (MO), and University of Wyoming (RM). The database, which contains information about flowering and fruiting times in addition to locality data, was used to plan dates and routes for collection trips.…”

The seed oil of Lesquerella and the closely related genus Physaria (Brassicaceae) is rich in hydroxy fatty acids (HFAs). HFAs and their derivatives are used to produce a variety of industrial products including lubricants, nylon-11, plastics, drying agents, protective coatings, surfactants, cosmetics, and pharmaceuticals. Lesquerella fendleri is being developed as a new crop for arid regions of the southwestern United States as an alternative source of HFAs. Between 1995 and 2001, 66 accessions from 28 species of Lesquerella were collected in the United States, 33 accessions from four species were collected in Mexico, and 41 accessions from 15 species of Physaria were collected from the southwestern United States. Mean seed mass ranged from 0.54 to 2.30 mg for Lesquerella compared to 1.70 to 5.80 mg for Physaria. Seed oil content ranged from a high of 32.2% in Lesquerella to a high of 35.4% in Physaria. The fatty acid profile of all species of Physaria and most of the lesquerolic-acid-rich species of Lesquerella contained from 30 to 55% lesquerolic acid, although several species contained Ͼ60%. These collections of wild germplasm provide a diverse gene pool that should enhance our breeding program in developing a domestic source of HFAs.

“…Gray) S. Watson, Fendler bladderpod (Brassicaceae), one of approximately 100 species in this genus, is native to the arid and semi-arid regions of south-western U.S. and is considered a promising new crop since it contains significant quantities of hydroxy fatty acid (Roetheli et al, 1991). Although this species can behave as annual or perennial (Rollins & Shaw, 1973), it is grown as a winter annual in the western United States (Dierig et al, 1993) and in arid lands of Argentina . This species is a candidate for domestication because of its seed and oil yield, lower seed dormancy and adaptation to irrigated arid lands (Dierig et al, 1993;Kehl & Erickson, 1995).…”

“…Lesquerella was established by Watson [36] as a North American genus. Later, Payson [39] recognized 52 species and Rollins and Shaw [35], and Rollins [37] recognized 69 and 83 species with 5 additional species published at a later date. Al-Shehbaz and O'Kane Jr. [38] believe that 4 additional new species exist in South America, including P. mendocina first described in 1893.…”

Lesquerella (Physaria fendleri) is a new oilseed crop that is being domesticated as an alternative crop for arid regions in the United States. As a member of the Brassica family, the species exhibits a high seed-oil content that can provide a source of hydroxy fatty acids for industrial use as source of bioenergy and by-products that can be utilized in livestock production. Germplasm evaluation and breeding activities on the crop have been done by the University of Arizona and the US Department of Agriculture (USDA). Lesquerella and other Physaria and Paysonia species have a substantial germplasm collection that is well characterized for phenotypic traits and oil profiles. There are several improved germplasm released by the USDA with higher oil content and seed yield, enhanced oil profile, abiotic stress tolerance, and harvest index which can be directly utilized for commercial production or used for crop improvement. Additional technologies that can aid breeding, such as molecular marker systems and genetic transformation systems, have been established. A few challenges remain to be surmounted for the crop to be commercialized. A continued concerted effort by public and private institutions may hasten the process of bringing this new crop to commercial production.
