Summary
A detailed analysis has been made of S genotypes in progenies derived from induced and spontaneous inbreeding processes in a clonal population of Lycopersicum peruvianum Mill. The results indicate that, in certain genetic backgrounds, induced inbreeding leads to the generation of a new S allele which usually first appears in the pistil of individuals otherwise homozygous for one of the parental specificities. When the change in specificity occurs in S heterozygotes, spontaneous self-compatibility is promoted and the new allele can be transmitted, via selfing, to the following generation.
The factors and mechanisms which may be involved in the generation of new specificities at the S locus of higher plants are discussed and preliminary evidence is provided which suggests that the hypothesis of mutation by equal crossing-over is not applicable to the present study.
Zusammenfassung
Es wurde eine ausführliche Analyse der S-Genotypen in Nachkommenschaften einer geklonten Population von Lycopersicon peruvianum Mill, nach induzierter und spontaner Inzucht gemacht.
Die Ergebnisse deuten an, daβ induzierte Inzucht bei einem bestimmten genotypischen Milieu zum Entstehen eines neuen S-Allels führt. Dieses erscheint gewöhnlich zuerst in den Griffeln einzelner Individuen, die im übrigen für eines der elterlichen Allele homozygot sind. Wenn die Änderung in S-Heterozygoten auftritt, dann wird die spontane Selbstkompatibilität gefördert. Das neue Allel kann durch Selbstung in die nächste Generation übertragen werden.
Die Faktoren und Mechanismen, die am Entstehen neuer Allele am S-Locus höherer Pflanzen beteiligt Scin können, werden diskutiert. Ein vorläufiger Hinweis wird dafür erbracht, daβ die Hypothese der Mutation durch equal crossing-over für die vorliegende Untersuchung nicht zutrifft.
