Abstract
‘Murasakizukin 3 gou’ was selected from the progeny derived from a backcross between the nonrecurrent parent ‘Murasakizukin 2 gou’ and recurrent parent ‘Murasakizukin’. ‘Murasakizukin 3 gou’ has the same growth properties, such as anthesis, harvest time, and the height of the main stem, as ‘Murasakizukin’, as well as similar amino acid contents, sugar contents, and creep rupture properties. The sensuality evaluation is higher. Its pods are brown at maturity. The seeds are spheroidal, black, and large in size (73.5 g/100 seed weight). In addition, ‘brown bloth symptom’, which is the major problem in ‘Murasakizukin’, is not observed in ‘Murasakizukin 3 gou’ due to resistance to A, A2, C, and D strains of the soybean mosaic virus. In Kyoto Prefecture, ‘Murasakizukin 3 gou’ will completely replace ‘Murasakizukin’ in 2016 and become available to consumers.
