Analiza prinosa i kvaliteta zrna ozimih sorti pšenice

Abstract

U radu je analizirana stabilnost prinosa zrna i sedimentacije proteina 10 genotipova ozime pšenice, primenom AMMI modela. Eksperimentalni deo ogleda je izveden tokom 2019/2020. godine na dva lokaliteta: Centar za strna žita i razvoj sela u Kragujevcu i Institut za krmno bilje u Kruševcu. Analiza varijanse je pokazala da su, u ekspresiji obe analizirane osobine, svi izvori varijacije (genotip, lokalitet i interakcija) ispolјili visoku statističku značajnost. Kao najstabilnije sorte za prinos zrna izdvojile su se NS Obala, PKB-Ratarica, Kruna i NS Futura, pri čemu su sve sorte ostvarili veći prinos zrna od opšteg proseka ogleda. U grupi stabilnih sorti za sedimentaciju proteina našle su se NS Obala, Kruna, NS Futura i NS Vlajna od kojih je samo Kruna imala iznadprosečne vrednosti analizirane osobine. Rezultati dobijeni u ovim istraživanjima ukazuju da je sorta Kruna pogodna za gajenje u različitim agroekološkim sredinama jer, pored visokih prosečnih vrednosti prinosa zrna i sedimentacije proteina, poseduje izraženu stabilnost.

The paper analyzed the stability of grain yield and protein sedimentation of 10 genotypes of winter wheat, using the AMMI model. The experiment was carried out during 2019/2020 in two localities: Centre for Small Grains and Rural Development in Kragujevac and Institute for Forage Crops in Kruševac. Analysis of variance showed that, in the expression of both analyzed traits, all sources of variation (genotype, locality and interaction) showed high statistical significance. NS Obala, PKB-Ratarica, Kruna and NS Futura stood out as the most stable varieties in terms of grain yield, with all varieties achieving a higher grain yield than the general average of the trial. In the group of stable varieties for protein sedimentation, there were NS Obala, Kruna, NS Futura and NS Vlajna, of which only Kruna had above average values of the analyzed traits. Variety Kruna is suitable for cultivation in different agro-ecological environments because, in addition to high average values of grain yield and protein sedimentation, it possesses pronounced stability.
