Karyomorphological and heterochromatin similarities among four Vigna species






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

Karyomorphological and heterochromatin similarities among four Vigna species

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.
