Abstract

In the present article a general survey is made of experimental studies in yielding ability seeds of cultivated plants. There are presented the best experimental evidences that the genetic inheritance, concluded in seeds of cultivated plants, composed of ontogenetic and phylogenetic inheritance. Ontogenetic heredity is formed within one year under the infl uence of environmental conditions during a course of cultivation of the parent plants, which have formed the seeds with altered yielding ability and within one further generation have realized this altered proprieties and then recreated again. This is a temporary or labile heredity. Phylogenetic heredity is formed over the entire period of the evolution of the species of plants. This is a continued or permanent inheritance. It was shown the cause that the basic laws of ontogenetic heredity were fi rst formulated by I. Michurin.
