Plasmon divergence in peanuts (Arachis hypogaea): A third plasmon and locus affecting growth habit

In a series of reciprocal crosses between peanut (Arachis hypogaea L.) cultivars from different regions and known testers, the cultivar HG1 from India was shown to have a third plasmon type, designated [G]. HG1 also has a third locus, Hb5 , which interacts with the plasmons and the loci described earlier. In the [G] plasmon, Hb1 and Hb5 are additive: plants having three or four dominant alleles have a trailing habit while the other nuclear genotypes produce in [G] erect plants. In the [V4] plasmon, Hb2 and Hb5 are complementary, [V4] Hb2-, Hb5-plants being trailing, the others erect. In the [G] plasmon, Hb2 and Hb5 are complementary, while in the [O] plasmon they are additive.
