Effect On Yield

Barley (Hordeum vulgare L. ’Bonanza’) was windrowed for five harvesting seasons at kernel moisture contents (KMC) (throughout this paper, wet-basis moisture content is used) ranging from about 55 to 19% at Melfort in the Parkbelt area of Saskatchewan. Windrowing the crop at 40% KMC did not cause a significant loss in grain yield or quality as measured by test weight, 1000-kernel weight, percent protein and phosphorus content as compared to harvesting at lower KMC. The results show that windrowing barley at 30–40% KMC will often reduce shattering and facilitate earlier combining. These results agree with earlier work reported.Key words: Hordeum vulgare L., harvesting, kernel moisture content, yield, quality

Field experiments with three barley (Hordeum vulgare L.) cultivars, Olli, Bonanza and Klages, were conducted for 3 yr at Beaverlodge, Alberta to determine the effect of harvest time and drying method on yield and quality. Plots were harvested at 5% kernel moisture content (KMC) intervals in the range of 45–15% and dried in the windrow or artificially dried. Yield, test weight, 1000-kernel weight, germination percent, protein content, phosphorous content and commercial grade were determined. Protein and phosphorous content were unaffected by the treatments. Windrowing at 40% KMC or less had little effect on yield or quality characteristics while threshing and artificially drying barley above 20% KMC reduced test weight and germination. Windrowing reduced yields of Olli and Klages barley by up to 19% compared to direct combining. Most treatments received feed grades, but the crop was most likely to meet Canada Western grades when windrowed at 30% KMC or less under favourable harvest conditions.Key words: Hordeum vulgare L., kernel moisture content, yield, quality

Hordeum Vulgare L

Somaclonal variation has been observed in plants derived via tissue culture in a number of crops, but evaluation has been on a small scale. This study was conducted to evaluate 72 tissue culture-derived barley (Hordeum vulgare L.) genotypes for somaclonal variation in replicated small-plot field trials. Twenty putative somaclones from the cultivar Abee, 20 from Deuce, 15 from Duke and 17 from Heartland were evaluated at three Saskatchewan locations during 1989. Little variation was observed between regenerants and their respective parent cultivars for days to head, height, yield and yield components. When variation did occur it was generally of negative value, i.e., later heading date; lower test weight, 1000-kernel weight, percent plumpness and yield. Of the four groups, those from Deuce and Duke exhibited the most variation. A 5-d difference in heading date was observed for one Duke derivative and 18 of the 20 Deuce derivatives were shorter than the Deuce control. From this study, it was concluded that somaclonal variation would be of no benefit in a plant-breeding program.Key words: Barley, field evaluation, tissue culture, Hordeum vulgare L.

A.Trof.: one coeleste (L.) A.Trof.) from 26 countries, 11 years and four places of reproduction was analyzed. Seeds with 5–8% moisture content were stored in chamber with unregulated and 4oC temperature. The possibility of seed storage under these conditions for at least 10 years without significant changes in germination has been established. The importance of meteorological conditions in the formation and ripening of seeds for their longevity is confirmed. The relationship between the decrease of barley seeds longevity and storage conditions, amount of rainfall, temperature regime during the growing season of plants is discussed.

Barley Cultivars

A brief historical sketch of the classification of barley (Hordeum vulgare L.) cultivars is presented along with reference to key reviews on this subject. Characters, utilized in the comprehensive study on the barley cultivars of North America by Aberg and Wiebe (U.S. Department of Agriculture Technical Bulletin 942), were subjected to a series of phenetic character analyses using an information theory model and a spatial autocorrelation model. The ranking of the 48 characters in order of their importance (for classification and identification purposes) from the character analysis by information theory was compared with the previous rating of characters made by Aberg and Wiebe and was found to differ significantly. Numerous trials of character analysis by spatial autocorrelation using various Minkowski distances, setting various values among three parameters, never yielded results comparable with those obtained by Aberg and Wiebe. Among those trials, a few combinations of values for the three parameters (X, Y, and Z) yielded results comparable with those obtained with character analysis by information theory. Those same combinations of values were found by Estabrook and Gates (Taxon, 33: 13–25) in their study of Banisteriopsis in 1984, where they also developed the method of character analysis by spatial autocorrelation. Kernel weight was found to be the most important character.

Pedigree and doubled haploid lines from seven crosses of barley (Hordeum vulgare L.) were compared over 2 years. The lines were tested, in a randomized complete block design, in row plots at Ste-Foy in 1977 and in hill plots at Brawley, California in 1978. There are significant differences between the two methods of pure line production for grain yield, 1000-kernel weight, plant height, resistance to lodging and date of maturity. Furthermore, these significant differences between doubled haploid and pedigree lines seem to be tied to wide crosses. After showing that doubled haploids are superior for resistance to lodging, we conclude that the use of doubled haploid lines must be seriously considered in a barley breeding program on the basis of improved selection efficiency and the short time required to get homozygous lines.

The effect of sowing rate (10-110 kg/ha) on the grain yield of barley (Hordeum vulgare L.) was determined from a total of 20 field experiments conducted in northern New South Wales from 1983 to 1986. Effects of sowing rate on kernel weight and grain protein percentage were also determined from 12 experiments conducted in 1985 and 1986. Two barley varieties were tested each year. In all years fallow plus winter rainfall was equal to or greater than average. Grain yield increased with higher sowing rates in most experiments, with the response curve reaching a plateau above 60-70 kg/ha. For 13 of the 40 variety x year combinations, grain yield fell at the highest sowing rates. Only in an experiment where lodging increased substantially with higher sowing rates was there a reduction in yield at a sowing rate of 60 kg/ha. The average sowing rate for which 5 kg grain was produced per kg of seed sown was 63 kg/ha. Grain protein percentage usually fell, and kernel weight invariably fell, with increasing sowing rate. Increasing sowing rates from the normal commercial rate of 35 kg/ha to a rate of 60 kg/ha typically increased grain yields by 100-400 kg/ha, decreased kernel weight by 0.4-2.0 mg, and decreased grain protein by up to 0.5 percentage points. In no case was the grain weight reduced to below malting specifications. It was concluded that sowing rates for barley in northern New South Wales should be increased to about 60 kg/ha.

Grain Filling Period

Seeding date is an important factor influencing productivity of barley (Hordeum vulgare L.). When conditions are conducive to early seeding or result in delayed seeding, producers need to know how cultivars will respond to these seeding situations. In this study, five cultivars (Abee, Harrington, Jackson, Noble and Virden) registered for western Canada were studied for 4 yr (1990 to 1993) when seeded early (late April or early May), in mid-May, in late-May, or late (mid-June) at Lacombe, AB. For all cultivars, early seeding resulted in grain yield advantages of 113 to 134% of the mean site yield, while with late seeding, grain yields were reduced to 54 to 76% of the mean site yield. The reduction in yield was least for Jackson, the earliest maturing cultivar tested. Late seeding reduced the period from sowing to emergence, vegetative period, grain-filling period, time from emergence to physiological maturity, test weight, grain yield, kernel weight, and tillers per plant; and increased plant height and percent thins. Late seeding had no significant effect on phyllochron, stand establishment, scald, lodging, protein content of the grain, kernel number per spike, and spikelet number per spike. Barley responded positively to early seeding in central Alberta, but when seeding was delayed (in this study to mid-June) the early and mid-maturing six-rowed cultivars with short phyllochrons performed better than the two-rowed and late six-rowed cultivars.
