An efficient chimera formation method by tissue culture combined with grafting was studied in Brassica. Cabbage cultivars “Ruby-ball” and “YR-ranpou” (Brassica oleracea) were used for intervarietal chimera formation. Seven-day-old seedlings leaving one of two cotyledons were approach-grafted and cultured in vitro (AGSC method). Chimeric shoots were obtained(More)
 The general characteristics of several graft-induced changes in pepper were investigated in a cross experiment. F1, F2, and BC1 progenies derived from crosses of the original stock and scion cultivars ‘Spanish Paprika’ and ‘Yatsubusa’, respectively, as well as their graft-induced variant strain G5S25 were analyzed for inheritance of the most conspicuous(More)
A line with genetic changes that was obtained from selfed seeds of the scion of an intraspecific pepper graft was used as a source of new characteristics in this breeding experiment. Five new variant lines and several sublines were bred by the use of this graft-induced variant strain and two other cultivars. Gradual introduction of the desired quantitative(More)
The stock abundance of the chub mackerel Scomber japonicus - a very important species for fisheries, particularly in Japan - in the Pacific Ocean off Japan has remained at a low level. For studying the population genetics of the chub mackerel, we isolated nine polymorphic microsatellite loci (12-31 alleles/locus; expected heterozygosity, 0.762-0.983) from(More)
The genetic nature of low capsaicin content in variant strains induced by grafting was elucidated by crossing the G5S23 strain with the two cultivars, ‘Yatsubusa’ (Capsicum annuum L. var. fasciculatum Ilish) and ‘Spanish Paprika’ (C. annuum L. grossum Sendt) originally used for grafting. Decreased capsaicin synthesis was a stable characteristic for at least(More)
Genetic changes induced by grafting were observed in soybean storage proteins, involving the 11S acidic subunit composition and Kunitz trypsin inhibitor. Changes from Gly 1 Gly 1to Gly 1 gly 1involved the 11S acidic subunit, and those from Ti 0Ti0 to Ti 3Ti0 involved the KTI in the first progeny (G1S1) in the scion (Gly 1 Gly 1 Ti 0Ti0, var. Kinzu) grafted(More)
Characteristics of fruit shape in the progeny from a graft-induced change were analysed. Non-pointed, typically inverted-blunt (two-lobed) fruit apex was observed in chimeric state within a scion of Yatsubusa grafted onto Spanish Paprika (inverted-blunt, three-or four-lobed fruit). This frequency of change in fruit shape was unstable in an early generation(More)
Capsaicin contents were measured in the progenies from the test crosses between the strain, G5S17 derived from fruit with the graft-induced change in fruit shape and the original two cultivars, Yatsubusa (Capsicum annuum L. var fasciculatum Ilish) and Spanish Paprika (C. annuum L. var. grossum Sendt) used for grafting. The strain, G5S17 contained a lower(More)
To elucidate the genetic nature of bushy plant type in the variant strains derived from grafting, testcrosses were made on the one hand between one of the variant strains, G5S17, and both Yatsubusa and Spanish Paprika, and on the other hand between the two cultivars. The bushy strain has more nodes and branches on the main stem than the two cultivars. This(More)
