Problems of species and genome in breeding
1994
Konarev, V.G.
The modern concept of the species as a complex biological system is based on the work of N.I.Vavilov, who was the first to emphasize the potential of a species for breeding. Realization of his ideas became possible only in the era of modern biology, with the advent of the latest biological methods of genetic and phylogenetic analysis of plants. Among these methods are molecular marking of genetic systems and biological structures with highly informative molecules of proteins and nucleic acids. These techniques are used to identify species, varieties, and biotypes; detect hidden variation in populations; analyze the genome, and estimate interspecies genomic relationships in allopolyploid plant complexes. Genomic and genetic studies of principal species of cultivated plants and their wild relatives have shown that the nuclear genome may be regarded as a genetic system of species category. The role of genetic variation in evolution and breeding; the genetic structure of species and its use for breeding; and the importance of cultivar, species, and superspecies gene pool levels for determination of genetically and morphogenetically complex plant traits are discussed
