Stabilnost prinosa zrna linija pšenice Centra za strna žita Kragujevac

Abstract

U radu je analizirana stabilnost prinosa 14 genotipova ozime hlebne pšenice. Eksperimentalni deo ogleda izveden je tokom 2013/2014. godine na tri lokaliteta (Kragujevac, Kruševac i Sombor). Analiza varijanse AMMI modelom za prinos zrna pokazala je da su svi izvori varijacije (genotip, spoljna sredina, njihova interakcija) značajno uticali na ekspresiju ove kompleksne osobine. U ukupnoj varijaciji ogleda, najveće učešće imala je interakcija genotip/sredina, a najmanje genotip. Izdvojeni su stabilni genotipovi pšenice, adaptirani na nepovoljne uslove spoljašnje sredine, koji mogu poslužiti kao roditelji za ukrštanja u budućim oplemenjivačkim programima.

In these investigations, the yield stability of 14 winter bread wheat genotypes were analyzed. The experimental part of the trial was performed at three locations (Kragujevac, Kruševac and Sombor) during 2013/2014. AMMI analysis of variance for grain yield showed that all sources of variation (genotype, environment, their interaction) had a significant effect on the expression of this complex trait. In the total variation of the experiment, the largest contribution had genotype/enviroment interaction, and genotype had the least. The most stable genotypes have been identified, which can be considered as a desirable genotypes, widely adapted to different agroecological conditions.
