    Domesticated crops are characterized by narrow genetic base reflecting one or more bottlenecks during millennia-long selection. As a result, current breeding programs are limited in available germplasm and are forced to deal with incremental improvements of yield, resistance, nutritional value, etc. Since the establishment of modern genetics and biotechnology, several new approaches have emerged to extend the genetic base and germplasm improvement. Among these methods, induced mutagenesis appeared as most useful conventional breeding tool. Although, its successful application currently requires good knowledge of modern molecular tools. In this paper we will make an attempt to overview SSR, ISSR and ISAP techniques as well as to offer examples of their application in tomato breeding programs.Π—Π° врСмя тысячСлСтнСй сСлСкции ΠΊΡƒΠ»ΡŒΡ‚ΡƒΡ€Π½Ρ‹Π΅ растСния Ρ…Π°Ρ€Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ·ΡƒΡŽΡ‚ΡΡ Π·Π°ΡƒΠΆΠ΅Π½Π½ΠΎΡΡ‚ΡŒΡŽ гСнСтичСской основы, ΠΎΡ‚Ρ€Π°ΠΆΠ°ΡŽΡ‰Π΅ΠΉΡΡ Π² ΠΎΠ΄Π½ΠΎΠΌ ΠΈ Π½Π΅ΡΠΊΠΎΠ»ΡŒΠΊΠΈΡ… эффСктах "Π±ΡƒΡ‚Ρ‹Π»ΠΎΡ‡Π½ΠΎΠ³ΠΎ Π³ΠΎΡ€Π»Ρ‹ΡˆΠΊΠ°".
