Description
Cemrosema brasillianum is a legume with high potential for pasture improvement in the semi-arid tropics with acid and infertile soils. Although genetic improvement for disease and pest resistance is taken into consideration, little is known about the species' breeding ·system. Moreover, no plant character inherited in simple Mendelian fashion has been reported for any Centrosema species. In experiments at Palmira, Colombia, 2 white-flowered accessions were hybridised with 6 violetflowered accessions, each of a different hue. Segregation for flower colourin F2 populations fitted a single gene model,colour being dominant over white, Hence, flower colour is a useful genetic marker, Because segregation for tones of violet did not fit any simple model, further studies on the inheritance of the different flower colour hues are required.
