Zur Genetik von Phaseolus Vulgaris XII. Über die Vererbung der Blüten- und Stammfarbe

“…Crosses between three pure lines with the constitution R s ill, R S ill and R s M showed all monohybrid segregation 3 : 1. Herewith it was proved that the three genes R, Sand M are different allels of the same gene R. 5. R shows strong linkage with the seed coat colour gene C (already stated by TJEBBES).…”

“…Von ----------------------------------E. v. TSCHERMAK wird also zuerst das Symbol 5 verwendet. KAJANUS (1914) 1. True breeding mottling is the effect of a mottling factor M. This mottling factor acts with most pigments.…”

Erfelijkheidsonderzoekingen bij boonen

“…Ook KAJANUS [5] vond indertijd, dat marmering en streping zich tegelijkertijd kunnen uiten, doch, evenals bij SINKS' materiaal in tegensteUing met de kruising kievits-• bruine boon, vermeldt deze auteur daarbij constante gemarmerdheid. De splitsing gemarmerdgestreept: alleen gemarmerd: alleen gestreept: ongemarmerd-ongestreept sehijnt bij hem volgens 9 : 3 : 3 : 1 plaats te grijpen.…”

The colourfactors of the seedcoat in phaseolus vulgaris L. and in Ph. multiflorus Willd

“…For all crosses, made with a white-seeded plant as one of the parents, have the same shortcoming because of the uncertainty in its genotypic constitution of this white plant; one and the same white race of beans may contain plants very different in factorial constitution with regard to the seedcoat-characters; as now known a white-seeded plant is white because of lacking a certain groundfactor, but it may contain a great many other factors, "that remain unvisible because of the absence of the groundfactor. Thus spontaneous hybridization may offer to us a very welcome subsidiary material for researches; their analysis has been applied by KAJANuS (1914), Lt~NDBERG and AAKERMAN (1917), TJEB~ES and KOOIMAN (1919), SIRKS (1920). Such an analysis is only complete~ if all seeds from an Fl-plant, that originated by spontaneou s hybridization, are available and accordingly the whole F 2--and following gene/'ations can be grown; only the papers of LUNDBERG and AAKERMAN and my own have been worked out in this manner; KAJANUS as also TJEBBWS and KOOIMAN have derived their materials from only one seed with a seedcoat divergent fro m those of the race of origin.…”
