Wheat and Barley Genetics and Pathology

The interaction of genotype x environment on yield and 1000 grain weight and test weight at four KG cultivars of barley (Rekord, Jagodinac, Maksa and Grand) was researched in this paper.The experiment was established on the experimental field of the Small Grains Center in Kragujevac (Serbia) during two growing seasons.The highest grains yield per area unit had, on an average, Maksa cultivar (4.935 t/ha).Average grains yield observed in the two-year period was the highest at Maksa cultivar, while the lowest yield was obtained by Jagodinac cultivar (3.882 t/ha).During the both years of investigation the highest average value of test weight achieved the Rekord cultivar (72.14 kg/hl and 73.22 kg/hl).The largest two-year average value of test weight was found in the cultivar Rekord (72.68 kg/hl), and lowest in cultivar Grand (65.69 kg/hl).During the both years of investigation the highest average value of 1000 grain weight achieved the Maksa cultivar (49.62 g and 51.86 g).The highest average 1000 grain weight was determined for cultivar Maksa (50.74 g).During 2010/2011, statistically significantly higher grain yield per area unit as well as 1000 grain weight was achieved, compared with 2009/2010.Investigations on genotype and environment interaction present the basis for further refinement and barley zoning.
