| Abstract: | Summary Karyotypic analysis of a spontaneous monosomic plant isolated from a population ofSesbania macrocarpa (2n=4x=24) revealed that one chromosome of the smallest set was missing. The absence of this chromosome caused a deleterious effect on the meiotic system of the plant, resulting in total male and female sterility. The origin of the species in this context is discussed.Thanks are due to Dr B. D. Patil, Indian Grassland and Fodder Research Institute for facilities and to Dr S. K. Gupta, for valuable suggestions. |
