The Law of homologous series' is given by Vavilov.
The law of homologous series was formulated by N. I. Vavilov in 1920. The Journal of Genetics published Vavilov's paper in 1922. This law established a parallel variability of homologous characters in taxonomically near species.
The Law of homologous series states that a particular variation observed in a crop species is also expected to be available in its related species.
