Karyomorphological and heterochromatin similarities among four Vigna species



Karyomorphological and heterochromatin similarities among four Vigna species



Genetic Resources & Crop Evolution 42(1): 57-60



Karyomorphological similarities among four species of the genus Vigna, V. unguiculata, V. luteola, V. oblongifolia and V. vexillata, were evaluated. Two different approaches were followed: cytomorphometrical determinations, carried out with an automated image analysis system to improve resolution, yielded some karyotypical indices; the distribution of heterochromatin bands was interpreted using a recently reported algorithm. Both methods led to similar results: the most karyologically similar species to V. unguiculata appears to be V. luteola, while V. oblongifolia appears to be the least related one.
