Frequencies of plasmon types in a germ plasm sample of peanuts, Arachis hypogaea

The plasmon constitution of 68 different accessions of cultivated peanuts (Arachis hypogaea L.) was studied in crosses with one or another of three testers: V4, VSM and HG1, having the [V4], [O] and [G] plasmons, respectively. The plasmons interact differently with three plasmon-sensitive nuclear genes, thereby determining whether the plants will be erect or trailing. From the phenotypes of the reciprocal F₁ hybrids it was concluded that the [G] plasmon of HG1 is rare-it is present in this cultivar and possibly in a few other; the [V4] plasmon is rare, being present in the V4 cultivar and possibly in a few other accessions; the [O] plasmon is widespread, being present in lines from various geographical origins and in at least three of the four botanical types of cultivated peanuts.
