How ‘Madsen’ has shaped Pacific Northwest wheat and beyond

Abstract

It is never known how well new cultivars will perform under commercial production until they are released and grown across different environments. Every cultivar released has a different impact on the region for which it was intended. Some cultivars are in commercial production for only a few years, whereas others are cultivated for decades. 'Madsen', a soft white winter wheat released in 1988 for production in the Pacific Northwest (PNW), has been in commercial production for 30 years. Once the dominant cultivar grown in the PNW, Madsen was produced mainly because of its high yield potential and excellent biotic stress resistance. Currently, Madsen is grown on limited hectares, replaced by many cultivars with higher yield potential; yet its legacy has gone far beyond commercial production. Madsen has been the parent of over 45 released cultivars, many of which were the lines that replaced it in commercial production. It is used as a parent mainly because of its excellent disease resistance to common diseases of the PNW. Madsen has also been used in research projects to identify disease resistance genes. In some cases Madsen was found to be carrying resistance genes the breeder was not aware of but were discovered later in research or field screenings. In this paper, we review the history of Madsen to determine what made it such a successful cultivar and parental line. Data were collected from multiple field trials and research papers and summarized for review.

The release of ‘LCP 85‐384’ and its contribution to the Louisiana sugar industry

“…Similar reports documenting the significant contribution of a single cultivar to an industry or region of production abound. In wheat (Triticum aestivum), Carter et al (2020) chronicled the significant contribution of the cultivar 'Madsen' (Allen et al, 1989;PI 511673) within and beyond the Pacific Northwest region of the United States. In sugarcane, two cultivars, 'NCo310' (Nuss & Brett, 1995) and 'NCo376' (Nuss, 2001), from South Africa superseded expectations in economic value during commercial production (Donovan, 1996) and also became the parents of many successful sugarcane clones (Zhou, 2013a) in South Africa and other sugar industries, including Taiwan (Shih & Juang, 1974) and the United States (Todd et al, 2015).…”

Important wheat diseases in the US and their management in the 21st century

“…Currently, completely resistant cultivars are not available, and hence cultivation of moderately resistant cultivars are encouraged in the PNW ( Carter et al., 2013 ; Carter et al., 2014 ; Carter et al., 2020 ). QTLs associated with cephalosporium stripe are compiled in Table 1 .…”

Mapping the quantitative field resistance to stripe rust in a hard winter wheat population “Overley” × “Overland”

“…Yr17 entered the cultivated hexaploid bread wheat germplasm pool through the French cultivar, "VPM1," which was derived from a bridge cross of Aegilops ventricosa Tausch, Triticum persicum, and T. aestivum (Bayles et al, 2000). As chronicled in Carter et al (2020), this breeding lineage was developed initially for eyespot resistance rather than for rust resistance. The USDA-ARS breeding program in Pullman, WA, led by Dr. Robert Allan, received two VPM1 derivatives from France in 1973 and used these as parents in crossing.…”
