The study was carried out to investigate the genotypic and phenotypic variability, heritability
and relationship between wheat yield components. A randomized complete block design
experiment was conducted, with sixteen wheat genotypes (Dukat, Dunavka, Fundulea 4,
Iskra, Jedina, Jugoslavija, Kavkaz, Mačvanka 1, Marija, NS-5804, Pitoma, Poljana,
Skopjanka, Tamiš, Vali PKA-7114 and Zvezda), in Novi Bečej (Vojvodina, Serbia), during
2016 and 2017 growing seasons. Grain weight per plant had the highest genotypic and
phenotypic variability (15.45 and 20.58%, respectively), while spike length had the lowest
ones (5.68 and 6.78%, respectively). High broad sense heritability was observed for plant
height (H2=86.19%) and spike length (H2=71.73%). Heritability was low in the case of spike
weight (H2=38.82%) and grain weight per spike (H2=26.56%), which indicates that
environmental factors had higher impact on expression of these traits in relation to genetic
factors. Path analysis reve...aled that spike weight and spike length had the highest significant
direct positive effect on the grain weight per plant, while thousand grain weight had the
highest significant negative effect. The grain weight per spike, number of grains per spike and
spike length had a significant indirect effect, through spike weight, on grain weight per spike.
