Effect of growing season and variety on quality of spring two-rowed barley

Abstract

Quality of barley consists of precisely defined grain quality attributes (grain weight, grading, grain protein concentration, etc.) and malt quality attributes (extract, viscosity, Kolbach index, etc.). Barley quality attributes are quantitatively inherited and greatly affected by environmental factors such as temperature, available water, nitrogen fertilizer and soil type. The main objective of this study was to determine the effects of genotype and growing conditions (year) on grain and malt quality attributes in barley grown under field conditions in the Pannonian zone. The eight spring two-row barley varieties were studied during a seven growing seasons (1998-2004) on the location Novi Sad (45?20'N, 15?51'E, 86 m asl). The growing season predominantly affected variation of the all studied grain and malt quality attributes of spring barley where its percentage of variance was 35.2%, 20.2%, 32.5%, 25.4%, 30.9%, 31.2%, and 38.5% for grain weight (GW), grading (GRA), grain protein content (GPC), viscosity (VIS), Kolbach index (KOL), Hartong number (HAR) and extract content (EXT), respectively. The interaction of GxE comprised of 28.4%, 64.5%, 38.2%, 54.0%, 39.6%, 41.2% and 23.7% of variation for GW, GRA, GPC, VIS, KOL, HAR and EXT, respectively. The genetic component of variance ranged from 11.1% for GRA to 35.0% for EXT. The heritability was the lowest for GRA-0.54 and the highest for EXT-0.91. Across growing seasons GW ranged from 39.6 to 46.1g, GRA from 76.7 to 91.1%, GPC from 12.1 to 13.5g 100-1g dm, VIS from 1.44 till 1.61m.Ps, KOL from 32.5 to 42,9%, HAR from 31.9 to 45.9VZ 45?C and EXT from 76.3 to 80.3% dm. Out of seven growing seasons EXT was acceptable in four ranging from79.2 to 81.4% dm. Although growing conditions in the Pannonian zone are less favorable for malting barley production in relation to western Europe it does not exclude malting barley production with acceptable quality in the Pannonian zone environments. The varieties Scarlett and Viktor performed quite acceptable quality in the Pannonian zone and may be recommended for commercial production in this region for malt industry.

The variation of agronomic traits associated with breeding progress in winter barley cultivars

“…These results are in agreement with reports by other authors for spring and winter barley (Pržulj et al, 2014;Mirosavljević et al, 2015 a). In our study, the ('Novosadski 595').…”

“…Variation in thousand grain weight is under strong influence of genetic and non-genetic factors (Pržulj et al, 2014). Our results also showed that Y, C and C × Y significantly affected thousand grain weight.…”

Evaluation of spring barley performance by biplot analysis

“…During the vegetative (pre-anthesis) period spike number per unit area and kernel number per spike is estab-lished, i.e. the number of kernels per unit area is formed (Pržulj et al 2014). On the other hand, kernel weight is formed during the period between anthesis and physiological maturity (Slafer 2003).…”

Productivity of facultative genotypes of oat in autumn and spring sowing

“…utiču na odnos izvor-akceptor asimilata tokom različitih faza rasta strnih žita. Interakcije genotip × spoljna sredina odgovorne su za najveći deo variranja u prinosu zrna kod strnih žita i predstavljaju značajnu mogućnost povećanja prinosa u određenim agroekološkim uslovima (Pržulj et al, 2014).…”
