Genetski potencijal ozime pšenice na zemljištu tipa smonice

Abstract

Poljski ogled sa sortama pšenice Pobeda, NS Vlajna i NS Azra postavljen je na zemljištu tipa smonica tokom vegetacionih sezona 2016/17. i 2017/18. godine. Cilj istraživanja je bio da se kod tri novosadske sorte pšenice gajene na slabo kiselom zemljištu analizira prinos, masa 1000 zrna i hektolitarska masa zrna. Najveće vrednosti ispitivanih osobina ustanovljene su u godini sa umerenim temperaturama i većom količinom padavina u vegetacionoj 2017/18. godini. Sorta Pobeda imala je najveći prinos zrna tokom dvogodišnjeg istraživanja. Najvećom masom 1000 zrna i hektolitarskom masom odlikovala se sorta NS Vlajna. Analizom varijanse ustanovljen je visoko značajan uticaj agroklimatskih uslova na hektolitarsku masu i visoko značajan uticaj genotipa na masu 1000 zrna i hektolitarsku masu kod ispitivanih sorti ozime pšenice.

The field experiment with the wheat varieties Pobeda, NS Vlajna and NS Azra was set up on the smonica-type soil during the 2016/17 and 2017/18 growing seasons. The goal of the research was to analyze the yield, mass of 1000 grains and hectoliter mass of three wheat varieties of Novi Sad grown on slightly acidic soil. The highest values of the tested properties were established in the year with moderate temperatures and a higher amount of precipitation in the 2017/18 vegetation year. The Pobeda variety had the highest grain yield during the two-year study. The NS Vlajna variety was distinguished by the largest mass of 1000 grains and hectoliter mass. Analysis of variance established a highly significant influence of agroclimatic conditions on the hectoliter mass and a highly significant influence of the genotype on the mass of 1000 grains and hectoliter mass of the tested winter wheat varieties.
