The Resistance of Twelve Varieties of Triticum Vulgare to Erysiphe Graminis Tritici

Abstract

SummaryA genetic study has been made af the resistance af 12 varieties af

Chromosomal location of powdery mildew resistance genes in Triticum aestivum L. (common wheat). 2. Genes Pm2 and Pm19 from Aegilops squarrosa L.

“…12633'. Furthermore, Pugsley & Carter (1953) described 'Ulka' as a mildew resistant cultivar that was introduced by a farmer from Russia into the USA. In the F1 progeny of test crosses between 'Ulka' and 'C.I.…”

Differential Reactions to Three Strains of Wheat Powdery Mildew (Erysiphe Graminis Var. Tritici)

“…The resistance of Sonora has been shown to be due to the dominant gene Mls (Pugsley and Carter 1953). Wolfe (1965) considered that Sonora and Sturgeon (also possessing Mls), gave inconsistent results when compared with each other and when tested in different environments.…”

“…Genes for resistance documented in cultivars tested in Table 1 are, on the terminology proposed by Pugsley and Carter (1953) and Pugsley (1961); as follows:…”

“…Since then numerous instances of strain variation have been recorded. These include reports by Vallega and Cenoz (1941) in Argentina; Taylor, Rodenhiser, and Bayles (1949), Lowther (1950), Powers, Schafer, and Caldwell (1959), and Scharen, Briggle, and Edwards (1964) in the United States of America; Pugsley and Carter (1953) and Pugsley (1961) in Australia; Nover (1957) in Europe;and Wolfe (1965) in the United Kingdom. The virulence on Asosan of certain strains (Powers, Schafer, and Caldwell 1959;Scharen, Briggle, and Edwards 1964) is of particular relevance to our studies.…”

Dr Maurice Vernon Carter– plant pathologist and epidemiologist, 1926–2014

“…Dr Maurice Vernon Carter ( Maurice Carter's early research concentrated on genes for resistance to barley powdery mildew (Pugsley and Carter 1953). In 1960 he spent a sabbatical leave at Rothamsted Experimental Station in the UK where he was greatly influenced by the expertise of Drs Philip Gregory FRS and Jim Hirst FRS on aerial and splash dispersal of fungal pathogens and worked with them on the development of spore trapping devices (Carter 1961).…”
