The composition of high-molecular-weight (HMW) glutenin subunits in 35 Finnish bread wheat cultivars was determined by SDS-polyacrylamide gel electrophoresis. One third of the varieties have one of two HMW glutenin subunit compositions and there are only 17 different compositions in all. Three cultivars, Antti, Kiuru and Panu, are genetically mixed for some of these subunits. Cultivar Tammi (II) contains a novel HMW subunit of glutenin, not detected in any bread wheat previously analysed, and is presumed to be coded by genes on chromosome 1A at the Glu-A1 locus. On the basis of previous work, which related individual subunits to bread-making quality, HMW glutenin subunit quality (Glu-1 quality) scores were calculated for the varieties. The results are related to the bread-making quality of Finnish wheats.

Hmw Glutenin

Variation in the electrophoretic banding patterns of high molecular weight (HMW) glutenin subunits of 274 hexaploid wheat (Triticum aestivum) varieties from China was examined by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Twenty-seven different major glutenin HMW subunits were identified. Each variety contained 3–5 subunits and 29 different glutenin subunit patterns were segregated. Seventeen alleles were identified based on comparison of subunit mobilities with those previously found for hexaploid wheat. Chinese hexaploid wheats exhibited particular allelic variation in glutenin HMW subunit composition and this variation differed from that found in wheats from Japanese and other countries. Average Glu-1 quality scores of 274 Chinese wheat varieties in the present study have been shown to be higher than that of Japanese wheats. Considerable genetic variation in the HMW glutenin subunit compositions of the Chinese wheats was observed in the present study and previously. Alleles from Chinese hexaploid wheat varieties have not been extensively introduced into Japan and other countries. The present data may indicate possible applications of Chinese germplasm in wheat breeding programs. To improve the wheat quality, genetic variation should be attempted through the introduction of genes of Chinese varieties into varieties in Japan and other countries.

Wheat Landraces

The endosperm storage proteins of 174 Japanese wheat (Triticum aestivum) landraces were fractionated by sodium dodecyl sulfate polyacrylamide gel electrophoresis to determine their high-molecular-weight (HMW) glutenin subunit composition. These are alleles for complex gene loci, Glu-A1, Glu-B1, and Glu-D1, that are present in Japanese hexaploid wheat landraces. These were identified by comparison with the subunit mobility previously found in hexaploid wheat. Twenty-four different, major glutenin HMW subunits were identified. Each landrace contained 3–5 subunits, and 17 different glutenin subunit patterns were observed for 13 alleles in Japanese landraces. Japanese landraces showed specific allelic variation in glutenin HMW subunits, different from those in non-Japanese hexaploid wheats.

Using sodium dodecyl sulphate-polyacrylamide gel electrophoresis, three new high-molecular-weight glutenin subunit/subunit combinations were detected in a Tunisian wheat cultivar (BT-2288) and these were designated bands 26, 7 + 11, and 5 + 9. Analysis of 112 testcross seeds revealed that the genes controlling them were additional alleles at Glu-A1, Glu-B1, and Glu-D1 loci, respectively. These alleles enhance the genetic variability available for cultivar identification and possibly for improving the bread-making quality of hexaploid wheat.Key words: Triticum aestivum, Glu-1 loci, high-molecular-weight glutenin subunits.
