Međusobni odnosi komponenti prinosa pšenice gajene u sistemu integralne proizvodnje

Abstract

U radu je urađeno istraživanje varijabilnosti i korelacija između prinosa i komponenti prinosa kod sorti ozime pšenice (Aleksandra, Aurelia, Planeta, Cipovka i Zemunska Rosa). Analizom varijanse su ustanovljene visoko značajne razlike za prinos i komponente prinosa između sorti, godina i njihove interakcije. Korelacije i Path analiza ukazuju da masa zrna po biljci ima statistički značajan i pozitivan direktni efekat (0,363*) na prinos zrna. Indirektno, ova osobina najveći doprinos povećanju prinosa zrna ostvarila je preko mase 1000 zrna (0,120) i mase zrna po klasu (0,102). Masa zrna po klasu i masa 1000 zrna imaju pozitivan direktni efekat na prinos zrna, ali bez statističke značajnosti. Pozitivna korelacija mase zrna po klasu i mase 1000 zrna sa prinosom zrna rezultat je indirektnog efekta koji ove osobine ostvaruju preko mase zrna po biljci.

In this paper, the variability and correlation between yield and yield components in winter wheat varieties (Aleksandra, Aurelia, Planeta, Cipovka and Zemunska Rosa) were investigated. Analysis of variance revealed highly significant differences for yield and yield components between cultivars, years and their interactions. Correlations and Path analysis indicate that grain mass per plant has a statistically significant and positive direct effect (0.363*) on grain yield. Indirectly, this trait made the biggest contribution to the increase in grain yield through the mass of 1000 grains (0.120) and the mass of grains per ear (0.102). Grain weight per ear and weight of 1000 grains have a positive direct effect on grain yield, but without statistical significance. The positive correlation of grain mass per ear and mass of 1000 grains with grain yield is the result of the indirect effect that these traits achieve through grain mass per plant.
