Ocena stabilnosti prinosa semena i komponenti prinosa NS konzumnih hibrida suncokreta primenom AMMI analize

Abstract

Povećana upotreba biljnih proteina u prehrambenoj industriji postavila je nove ciljeve oplemenjivačkom programu konzumnog suncokreta. Ispitivanje adaptabilnosti novih konzumnih hibrida suncokreta je važan deo programa oplemenjivanja. Petnaest NS konzumnih hibrida suncokreta ispitivano je tri godine na lokaciji Rimski Šančevi, u ogledu postavljenom kao randomizovani blok dizajn sa tri ponavljanja. REML slučajni model je korišćen za procenu efekata hibrida, godina i njihove interakcije, dok je AMMI analiza primenjena za određivanje interakcije genotipa i okruženja. Upoređen je efekat genotipova (G), okruženja (E) i njihove interakcije (GE) s obzirom na njihov doprinos ukupnoj varijansi. Za prinos semena glavni efekat E (49,32%) je bio važniji od GE (38,98%) i G efekata (11,70%), što pokazuje da prinos semena ispitivanih genotipova suncokreta više zavisi od uslova sredine nego od genotipa.

The increased use of vegetable proteins in the food industry has imposed new goals on the confectionery sunflower breeding program. Testing the adaptability of new NS confectionery sunflower hybrids is an important part of the breeding program. Fifteen NS confectionery sunflower hybrids were tested over a period of three years in an experiment set up as a randomized block design with three replications at the Rimski Šančevi location. The REML random model was used to evaluate the effects of hybrid, year, and their interaction, while AMMI analysis was applied to determine the interaction between genotype (G) and environment (E). The effect of G, E, and their interaction (GE) was compared with respect to their contribution to the total variance. For seed yield, the main effect of E (49.32%) is more important than the GE effect (38.98%) and G effect (11.70%), which shows that sunflower seed yield, of investigated hybrids, depends more on environmental conditions than on genotype.
