Analiza stabilnosti mase ploda kod linija dinje AMMI i BLUP metodom

Abstract

U ovom radu su ispitivana dva metoda analize stabilnosti kod 23 genotipa dinje gajenih tokom osam vegetacionih sezona na lokalitetu Smederevska Palanka (ogledno polje Instituta za povrtarstvo). Analiza je vršena AMMI metodom i BLUP metodom, koje se zasnivaju na analizi interacije genotip x spoljna sredina (G×E). Najvažniji cilj rada je bio da se odrede genotipovi dinje koji se karakterišu stabilnošću bez obzira na uslove spoljašnje sredine. Ogledi su sprovođeni u periodu od 2014. do 2021. godine. Ispitivana osobina je bila masa ploda. Utvrđeno je da se genotipovi, čija je prosečna masa ploda ispod ukupnog proseka, karakterišu manje varijabilnim vrednostima mase ploda u odnosu na genotipove koji su prinosniji. Kao najstabilniji genotipovi, bez obzira na vodni režim u toku cvetanja i zametanja plodova izdvojili su se G3 i G16 (AMMI analiza) i G7, G14 i G20 (BLUP analiza).

In this paper, in 23 melon genotypes grown during eight growing seasons at the Smederevska Palanka location (the open field of the Institute of Vegetables), two methods of stability analysis were examined. The analysis was performed using the AMMI method, and BLUP method, which are based on genotype x environment (G×E) interaction analysis. The most important goal of this paper was to determine the melon genotypes that are characterized by stability regardless of the conditions of the environment. The trials were conducted in the period from 2014 to 2021. The examined trait was fruit weight. It was determined that genotypes whose average fruit weight is below the overall average are characterized by less variable fruit weight values compared to genotypes that are more productive. G3 and G16 (AMMI analysis), and G7, G14, and G20 (BLUP analysis) stood out as the most stable genotypes regardless of the water regime during the flowering and fruit set.
