Abstract

The occurrence of damaged grains was studied in 12 barley genotypes in a three-year period. The occurrence of grains with physiological split of lemma and endosperm was generally low. Split of palea and endosperm was mostly affected by the genotype (10%) and it was recorded most frequently in the genotype Heris. Incomplete overlapping of husks was also markedly affected by the genotype (10%) and it occurred most frequently in the genotype Scarlett. Sprouted grains and grains of green color occurred minimally. Black points were affected by year (21%) and genotype (15%). This damage was most frequently reported for the genotypes Camera and Jersey. Surprisingly, the occurrence of grains with apparently moldy husks was markedly affected by the genotype (25%), less substantially by the location (10%) and minimally by year (3%).
