An Ovule Culture Technique for Producing Interspecific Lesquerella Hybrids

  title={An Ovule Culture Technique for Producing Interspecific Lesquerella Hybrids},
  author={P. Tomasi and D. Dierig and G. Dahlquist and J. Janick and A. Whipkey},
INTRODUCTION Lesquerella [Lesquerella fendleri (Gray) Wats., Brassicaceae], is a potential new oilseed crop, producing an unsaturated, hydroxy fatty acid (lesquerolic acid, C20:1-OH) with properties similar to imported castor oil (Dierig et al. 1993). The cultivated L. fendleri has demonstrated a narrow range of genetic variation determining hydroxy fatty acid seed oil content (Dierig et al. 2001). Germplasm evaluations completed at the USDA, Agricultural Research Service, US Water Conservation… Expand

Germplasm Improvement to Develop Commercially Viable Lines of the New Oilseed Crop Lesquerella
Improved germplasm released by the USDA with higher oil content and seed yield, enhanced oil profile, abiotic stress tolerance, and harvest index are released which can be directly utilized for commercial production or used for crop improvement. Expand
Evaluation of new Lesquerella and Physaria (Brassicaceae) oilseed germplasm.
These collections of wild germplasm provide a diverse gene pool that should enhance the breeding program in developing a domestic source of HFAs. Expand
A new interspecific hybrid of Torenia obtained through ovule culture
This study shows that ovule culture is a powerful tool for overcoming the crossing barrier in interspecific crosses in Torenia, and achieves the first interspecific Torenian hybrid obtained using T. siamensis. Expand
Neglected Oil Crop Biotechnology
In this chapter emphasis has been given to current biotechnology research and progress for the improvement of these neglected oil crops. Expand


Wide hybridization in Brassica
The in vitro culture of ovaries, ovules, and seeds increased the frequency of obtaining hybrid seeds and plants: the most effective method was ovary culture followed by ovule culture. Expand
Registration of WCL‐LY2 High Oil Lesquerella fendleri Germplasm
WCL-LO3 has an improved oil concentration, harvest index, and seed yield compared to previously released germplasm, and should be suitable for geographic regions similar to the arid southwestern USA. Expand
Lesquerella commercialization efforts in the United States
Abstract Lesquerella fendleri (Gray) Wats. is a promising new crop for cultivation in the western United States. Its oil-bearing seed contains high amounts of the hydroxy fatty acid (HFA),Expand
In vitro multiplication of a sterile interspecific hybrid, Brassica fruticulosa x B. campestris
The results demonstrate the efficacy of an in vitro method in producing a large number of hybrid plants and fertile amphidiploids from incompatible crosses that yield very few hybrid seeds/seedlings. Expand
Production of wide hybrids and backcross progenies between Diplotaxis erucoides and crop brassicas
D. erucoides is considered to be a close relative of B. campestris and B. oleracea, but incompatibility barriers of this species with different cultivars do not reflect this relationship and backcross pollinations with the pollen of the respective cultivars yielded BC progenies in the hybrids.

Distant Hybridization of Crop Plants
The purpose of the book is to present an overview of basic and applied aspects of hybridization of distantly related species and genera of crop plants to serve researchers and scientists working on plant breeding, genetics, biology and agriculture. Expand
An in vitro chromosome doubling method for clovers (Trifolium spp.)
A new technique for chromosome doubling of clover (Trifolium sp.) axillary meristems via in vitro colchicine application is reported, and plant material utilized included T. pratense. Expand
