Breeding effects on sensitivity of barley grain weight and quality to events of high temperature during grain filling

2005

Temperature is one of the most important factors affecting grain quality in the majority of cereal growing areas. It has been shown that brief periods of high temperature during grain filling can reduce grain weight and quality. However, it is not known whether breeding for increased yields has altered the sensitivity to high temperatures after flowering. Four malting barley cultivars, chosen from previous studies to represent a series of successful breeding releases in Argentina, were sown under field conditions. The high temperature treatments consisted of increasing the spike temperature by about 5 • C for 6 h/day (from 10 am to 4 pm) for 20 days starting nine days after flowering (DAF), or for two periods of 10 days each, between 9 to 19 DAF or from 20 to 29 DAF. In all cultivars, grain weight and screening percentages decreased significantly with the treatments. In general, the two more modern cultivars (Q. Pampa and Q. Ayelén) were more sensitive to heat stress than the older ones (Heda and Unión). A similar pattern was found for malt extract. Thus it appears that breeding for higher yields has concomitantly increased sensitivity of grain weight (and yield) and quality to the episodes of high temperatures during the grain-filling period in barley.

“…A lot of studies describing morphological, fenological and agronomic characters of barley have been published 1,30,36,41,66 , but only a few papers have dealt with the progress of malting quality 4,37,38,63 . Yields of barley grain and other cereals have risen dramatically during the past century.…”

J. Inst. Brew. 115(4), 279-291, 2009This paper summarizes the results of study of malting and agronomic characteristics of barley varieties grown in the territory of the Czech Republic over the period . Mean year-onyear increase in the grain yield was 53 kg/ha. Mean increase in TGW was 0.177 g/year over the studied period. Accumulation of protein in the studied varieties declined ca by 12%. Varieties from the beginning of the 21st century displayed a 4% higher extract content than those grown in the second half of the 1950s. Mean year-on-year increase in extract (d.m.) was a 0.0641 percentage point. By the end of the 1970s most of the varieties achieved values of diastatic power higher than 300°WK. In the 1970s to 1980s, diastatic power declined to under the level of 300°WK. In the 2nd half of the 1990s and at the beginning of this century, activity of amylolytic enzymes increased considerably in some modern varieties and values of diastatic power frequently moved over 350°WK. Activity of proteolytic enzymes increased by 6%. Mean year-on-year increase in Kolbach index was a 0.1456 percentage point. Value of relative extract at 45°C increased by 3%. Mean year-on-year increase in relative extract at 45°C was a 0.0645 percentage point over the studied period. Value of the apparent final attenuation, a trait characterizing quality of wort composition, increased by 3%. Mean inter-year increase in apparent final attenuation was a 0.0756 percentage point.

BACKGROUND: This paper presents a multivariate approach to investigate the influence of barley variety, timing of nitrogen fertilisation and sunn pest infestation on malting and brewing. Four spring and two winter barley varieties were grown in one location in southern Europe. Moreover, one of the spring varieties was infested with sunn pest, in order to study the effects of this pest on malting quality, and subjected to different nitrogen fertilisation timing regimes. The samples were micromalted, mashed, brewed and analysed.
