The traits of the root system enable the plant to react, adapt and develop in different environmental conditions. The architecture of the root system is a basic component of the productivity of plants and involves morphological, anatomical and physiological characteristics of root. The studies of the architecture of the root system (RSA) and its modelling is in progress. The paper points to the importance and strategies of developing plant phenotyping, their advantages and limitations as well as possibilities of practical application to plant breeding and production technology. Also, a semi-hydroponic platform for phenotyping of the root system is shown, accompanied by developed models for the construction of the architecture of the underground part of the plant under certain environmental conditions that allow the simulation of biological, physical and chemical processes in the soil. Different models that follow the development of the root system are most often the result of the analysis of morphological and physiological characteristics while their empirical approach has so far been tested on a large number of plant species. Osobine korenovog sistema omogućuju biljkama da reaguju, prilagode se i razvijaju u različitim uslovima spoljašnje sredine. Arhitektura korenovog sistema je jedna od osnovnih komponenti produktivnosti biljaka i podrazumeva morfološke, anatomske i fiziološke osobine korena. Danas se sve više istražuje arhitektura korenovog sistema (Root system architecture, RSA), kao i njegovo modeliranje (modelling plant root system). U radu se ukazuje na značaj i strategije razvoja fenotipizacije biljaka, njihove prednosti i ograničenja, kao i mogućnosti praktične primene u oplemenjivanju biljaka i tehnologiji proizvodnje. Takođe prikazana je i polu–hidroponska platforma za fenotipizaciju korenovog sistema, kao i razvijeni modeli za konstrukciju arhitekture podzemnog dela biljke u određenim uslovima sredine koji omogućuju simuliranje bioloških, fizičkih i hemijskih procesa u zemljištu. Različiti modeli koji prate razvoj korenovog sistema najčešće su rezultat analize važnijih morfoloških i fizioloških osobina, a njihova empirijska primena je do sada testirana na većem broju biljnih vrsta u svetu.
