| 0 | PI 675008 | 'Mela CL+' | Triticum aestivum L. subsp. aestivum | Washington, United States | PVPO | | Not Available | 2015 | DEVELOPED | | | | | | Cultivar | ‘Mela CL+’ was developed and released in the year of 2013 as soft white common winter wheat variety carrying two-gene Clearfield technology by Agricultural Research Center of Washington State University. It has two mutant forms of the acetolactate synthase (ahasl-1d and ahasl-1b) gene; that provide resistance against imidazolinone group of herbicide BeyondTM. These mutations have been used to develop wheat varieties resistant to the herbicide and this technology is commonly known as ‘Clearfield technology’. Since, it carries the two-gene Clearfield technology, therefore it expects to provide more protection against herbicide imazamox. The major utility of Mela CL+ is for controlling annual grassy weeds, such as jointed goatgrass, feral rye, downy brome, Italian ryegrass and wild oats, those are the major problem in wheat production of Washington State causing significant economic losses. Mela CL+ is a semi-dwarf, common head type and white straw and glumes. It recovered in the background of Eltan in only two backcrosses and few selfing cycles. In addition to the two-gene Clearfield traits, it has similar to better resistance to the snow mold and Cephalosporium Stripe than Eltan. Mela CL+ has better stripe rust resistance to their recurrent parent variety ‘Eltan’. It adapted for production in the semi-arid region especially for <12 inches rainfall regions including Central Washington area and a replacement/complement to the single-gene Clearfield wheat varieties grown in PNW region. The end-use quality performance of Mela CL+ is equal to better than other high yielding varieties grown in PNW and it classified as desirable quality. | 1926879 | PI 675008 |
