Linkage between loci controlling nodulation and testa variegation in peanut.
Linkage of loci controlling nodulation (N(1)) and testa variegation (V) was studied for cultivated peanut (Arachis hypogaea L.). The lines M4-2 (nonnodulating, variegated; VVn(1)n(1)n(2)n(2)N(3)N(3)) and UF 487A (nodulating, nonvariegated; vvN(1)N(1)n(2)n(2)N(3)N(3)) were used as parents in the crosses M4-2 x UF 487A, M4-2 x (UF 487A x M4-2), and their reciprocals. Individual plants were evaluated for nodulation and testa variegation in the F(1), F(2), F(3), F(1)BC(1), and F(2)BC(1) generations. Data indicate that the N(1) and V loci are linked with calculated crossover percentage of 7.1%.
