title: Linkage between loci controlling nodulation and testa variegation in peanut.
abstract: 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%.
