Developing Superior Oilseed and Mustard Cultivars for Brassicaceae
Brassica crops have shown excellent rotational benefits when grown with small grain cereals but few cultivars are available that have specific adaptation to dry land agricultural conditions in the US. To develop superior Brassica oilseed and mustard cultivars that are highly adapted to a wide range of dryland and irrigated agriculture of Idaho and other US regions,and hence offereing great grower options, while reducing input costs, and being more competitive in international markets. The aim of this breeding program has been to offer growers in the region greater flexibility on choice of crop and cropping rotation. Availability of yellow and oriental mustard has offered Pacific Northwest growers more crop rotation benefits and helped in increase export potential. Similarly, Athena winter canola has offered grower the opportunity to include a
non-cereal fall planted crop into their rotations. Many growers in the region use Persuit herbicide on pea or lentil, which limits rotations as there is a five year plant-back restriction on either canola or mustard. The new Raptor resistant cultivars are highly tolerant to Pursuit carry over and will allow growers to include a legume and Brassica in a six year rotation with cereals. Field trials on efficacy of pest control and phytotoxicity of Brassica is highly promising and the potential for developing high glucosinolate intergeneric hybrids remains strong and could provide an alternative to highly toxic synthetic soil fumigation.
