Three potato cultivars developed by the Colorado Potato Breeding and Selection Program, Nonpareil Russet, Maritime Russet and Canada Rose, will be released and protected in both Canada and the United States. Nonpareil Russet is a high yielding dual purpose russet selection with fresh market and processing potential. Nonpareil Russet, previously known as CO98067-2RU, was derived from a cross of Silverton Russet and Top Cat. Nonpareil Russet has a higher total yield potential (476 cwt/A) and a higher percentage of US No. 1 tubers (84%) than Russet Norkotah. Nonpareil Russet is resistant to PLRV and powdery scab. Maritime Russet, previously known as CO97087-2RU, was derived from a cross of CO87009-4 x W1005. Maritime Russet has a higher yield potential (433 cwt/A) and a higher percentage of US No. 1 tubers (85%) than Russet Norkotah. Tubers are resistant to hollow heart, second growth, shatter bruise and growth crack. Maritime Russet is resistant to Fusarium solani, powdery scab, and corky ringspot (TRV). Canada Rose, previously known as CO00227-2R, was derived from a cross of Colorado Rose and CO94065-2R. Canada Rose is a fresh market red with early maturity. Canada Rose has higher yield potential (427 cwt/A) than Red LaSoda. Tubers are resistant to hollow heart, second growth, growth crack, blackspot bruise and shatter bruise. Canada Rose has shown to have good red skin color retention in storage. Advanced testing, seed increase, and commercial evaluation for all three cultivars was assisted by the Southwest Regional cooperators and Western Regional cooperators, seed and commercial growers and other private cooperators in the Western United States. Certified seed stocks for Nonpareil Russet, Maritime Russet and Canada Rose are available through Canadian Eastern Growers Inc.
