Analiza G×E interakcije za visinu biljke plavog patlidžana (Solanum melongena L.) po ammi modelu

Abstract

U radu je analizirana stabilnost osobine visina biljke 20 divergentnih genotipova plavog patlidžana koji su deo kolekcije Instituta za povrtarstvo Smederevska Palanka. Poljski mikroogledi su izvedeni na tri lokaliteta (Smederevska Palanka, Kusadak i Vranovo). Analiza varijanse AMMI modela pokazala je da postoje značajne razlike između genotipova, lokaliteta, kao i njihovih interakcija (G×E) za visinu biljke. Od ukupne sume kvadrata, 91,6% variranja odnosio se na efekat genotipa dok se svega 4,11% variranja može pripisati efektu lokaliteta. Rezultati dobijeni u ovom istraživanju ukazuju da je 5 proučavanih genotipova pokazalo stabilnost ove osobine na različitim lokalitetima. Na osnovu ASV vrednosti za visinu biljke, zaključuje se da je najveća stabilnost utvrđena na lokalitetu Vranovo koji je po rangu na prvom mestu i sa koeficijentom AMMI stabilnosti 2,16.

In the experiment the stability of the trait plant height, for 20 divergent eggplant genotypes from the GenBank of Institute for Vegetable crops Smederevska Palanka was analyzed. Field microtrials were carried out at three locations (Smederevska Palanka, Kusadak and Vranovo). The analysis of variance of the AMMI model showed significant differences between genotypes, localities and their interactions (G×E) for plant height. From the total sum of squares, 91.6% of the variation was related to the genotype effect, while only 4.11% of the variation can be attributed to the locality effect. The results obtained in this research indicate that 5 studied genotypes showed the stability of this trait in different localities. Based on the ASV value for plant height, it is concluded that the highest stability was determined at the Vranovo location with an AMMI stability coefficient of 2.16.
