Variability of agronomic properties of wheat

Abstract

In order to investigate variability of yield, number of grains per m2 and 1000 grain weight, it was selected 39 different genotypes of wheat. Field trial was set up at Rimski Sancevi in 2008/2009 season. On the basis of geting results we find out significant differences in yield, number of grains per m2 and 1000 grain weight among investigated genotypes. The highest averrage grain yield (9.25 t/ha) has had variety Dragana, and the lowest yield (3.08 t/ha) has had variety Banatka. The highest number of grains per m2 (51532) has had variety Sana, and the lowest number of grains per m2 (22360) has had variety Bankut 1205. The highest 1000 grain weight (57.1 g) has had variety KG 56, and the lowest 1000 grain weight (33.2 g) has had line NS3-5299/2. Positive but small correlation among studied traits show a large portion of ecological variance in total variation of investigated traits.
