Intraspecific mixtures may be a means of enhancing the genetic variability of modern crops while retaining the advantages of yield, quality, and stress tolerance of modern cultivars. Two- and three-way barley (Hordeum vulgare L.) mixtures of the cultivars Abee, Noble, Tukwa and Virden, were studied at Botha, Lacombe and Olds, Alberta, from 1992 to 1994. Treatments consisted of the four cultivars as monocrops and in 6 two-way and 3 three-way mixtures grown at a seeding rate of 250 seeds m−2. Tukwa as a monocrop had the highest rank and best stability for grain yield of all the treatments. Grain yields of the mixtures usually fell between the yields of the respective monocrops and were often better than the weighted mean yield of the monocrops indicating that many mixtures were more effective at using resources than the monocrops. Of the mixtures, Tukwa:Noble, Tukwa:Abee:Virden and Noble:Virden had the best rankings and stability for grain yield. Test weights, kernel weights, percent thins, lodging, disease incidence and protein content of the mixtures were intermediate to those of the monocrops. Mixtures containing the two-rowed cultivar Abee had higher test weight and protein content than mixtures composed of only six-rowed cultivars. Lodging and disease ratings were lower for the mixtures composed of only six-rowed cultivars than those with Abee. In these intraspecific barley mixtures, Virden was often the most competitive cultivar while Tukwa was the least. Competitive ability was not associated with yield potential, tillering, or row-type.

Hordeum Vulgare L

We tested six winter barley (Hordeum vulgare L.) cultivars in a small plot field experiment, measuring photosynthesis and other parameters three times during the growing season. Four genotypes—Andoria, Jakubus, Paradies and Zophia—are new, promising varieties with requirements of intensive technology, high yield potential and very good disease resistance. The two popular Hungarian varieties (KG Apavár and KG Puszta) are relatively old but they have good tolerance to extreme ecological conditions and outstanding resistance and winter hardiness. The aim of our research was to test the new varieties’ performance. Several recent studies found close connections among various photosynthetic parameters in barley, and we confirmed that in our research. There were significant differences between the varieties in the assimilation rate—the highest values were measured at the BBCH 47–49 stage (end of booting), except Jakubus and Zophia, where the highest values were at BBCH 73–75 (milk ripe). The cultivars’ response to irradiation change varied, especially at higher photosynthetic photon flux density (PPFD) levels. In April and May, the plants were in drought stress according to the intercellular CO2 level and the total conductance to carbon dioxide. The differences between the air and leaf temperature were also low, indicating water stress, but the assimilation rate was relatively high (9.07–14.09 µmol m−2 s−1).We found a close connection between normalized difference vegetation index (NDVI) values and grain protein content in each of the tested barley cultivars. The correlation was significant, at p = 0.01 level. The protein yield per hectare was determined rather by grain yield than protein content. The relationship between the NDVI values and grain yield was moderate, but NDVI values and protein content are in strong correlation.

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.

Yield Responses

Little information is available on the response of two-rowed barley (Hordeum vulgare L.) cultivars to seeding rate in central Alberta. The objective of this research was to compare the effects of seeding rates of 129–344 seeds m−2 (50–140 kg ha−1) on the agronomic response of two- and six-rowed barley grown in central Alberta. Grain yields of 5.8–6.1 t ha−1 were not affected by seeding rates in 1990 and 1991 at Lacombe. As seeding rates increased in 1992, grain yields at Lacombe increased from 6.4 to 7.8 t ha−1; at Olds, from 3.5 to 4.0 t ha−1; and at Botha for the 129 seeds m−2 treatment, yields were only 5.5 t ha−1, compared with 5.8 to 6.0 t ha−1 for the other treatments. Effects of seeding rate on test and kernel weights varied between location–years. Tiller numbers m−2 were found to increase at higher seeding rates for the two-rowed cultivars, Abee and Harrington, while for the six-rowed cultivars, Noble and Virden, these numbers remained constant. Node numbers spike−1 decreased with higher seeding rates for both two- and six-rowed cultivars. There was little effect of seeding rate on kernel number spike−1 for the two-rowed cultivars, while for the six-rowed cultivars this number decreased. Although the two- and six-rowed cultivars differed in their partitioning of yield and the effects of seeding rates on these components, their yield responses to seeding rate did not differ. Recommended seeding rates for barley in central Alberta should be above 129 seeds m−2 (50 kg ha−1). To maintain high kernel and test weights, seeding rates for barley grown in central Alberta for malt quality should range from 172 to 258 seeds m−2. When conditions warrant accelerated development, seeding rates of 300 or more seeds m−2 should be used. Key words:Hordeum vulgare, management, yield components

Barley Protein

The relationship between the protein content of grain, plant grain yield and yield components (number of ears per plant, number of grains per ear, and 1000-grain weight) was determined for six cultivars of winter barley, four six-rowed (Hordeum vulgare L.) and two two-rowed (H. distichon L.), grown in Granada (Spain) during 1979, 1980 and 1981. Each cultivar was grown with two levels of nitrogen fertilizer (25 and 40 kg/ha) applied both at seeding and as a top-dressing. Protein content of the grain, grain yield and number of ears per plant varied significantly with genotype, level of nitrogen fertilizer applied at seeding and year. Protein content of the grain was positively correlated with plant grain yield. Both factors were correlated principally with the number of ears per plant, and to a lesser extent with grains per ear and grain weight. The protein content and grain yield depended on the crop dry weight or biomass during the vegetative period (source capacity) which was in turn, related to the leaf area index.Key words: Barley, protein content, grain yield, Hordeum vulgare L., Hordeum distichon L.

Genotype by environment interaction (GEI) of 18 barley varieties was assessed during two successive rabi crop seasons so as to identify high yielding and stable barley varieties. AMMI analysis showed that genotypes (G), environment (E) and GEI accounted for 1672.35, 78.25 and 20.51 of total variance, respectively. Partitioning of sum of squares due to GEI revealed significance of interaction principal component axis IPCA1 only On the basis of AMMI biplot analysis DWRB 137 (41.03qha–1), RD 2715 (32.54qha–1), BH 902 (37.53qha–1) and RD 2907 (33.29qha–1) exhibited grain yield superiority of 64.45, 30.42, 50.42 and 33.42 per cent, respectively over farmers’ recycled variety (24.43qha–1).

Hill Plots

Provided they reliably predict row plot performance, hill plots should be useful for doubled haploid recurrent selection in malting barley (Hordeum vulgare L.). The primary objective of this research was to compare hill and row plot expression of agronomic and malting quality traits in an array of elite spring habit barley germplasm grown under irrigated conditions. A supporting objective was to identify an appropriate seeding rate for hill plot evaluation. Eight-replicate hill plots at four seeding rates (10, 20, 30, and 40 seeds per hill) were compared with adjacent four-replicate row plots in each of three environments. Genotype and genotype × environment interactions were significant for most agronomic traits in both plot types. Significant, linear genotype responses to hill plot seeding rates were observed for most agronomic traits. Seeding rate had no consistent effect on the expression of malting quality. The percentage of lines in common in the two plot types at 25 and 50% selection intensities was the most useful comparison statistic and indicated hill plot selection should be effective for most agronomic and malting quality traits. Although yield heritability estimates were consistently high in both hill and row plots, there was little relationship between trait expression in the two plot types. Differential tillering in response to hill plot competition is likely responsible. A seeding rate of 10 seeds per hill should be appropriate in preliminary screening for traits amenable to hill plot selection in irrigated spring habit malting barley.Key words: Hordeum vulgare L., malting quality, breeding methods, barley
