AC Harper is a six-row yellow aleurone, hulled, spring feed barley with smooth awns, suitable for the Canadian prairies. AC Harper was developed from a cross between a scald resistant backcross line of Galt and BT364, which has high grain yield and strong straw. It has a combination of high yield potential, good resistance to lodging, short straw, and resistance to scald. AC Harper has improved kernel plumpness, protein content, and kernel colour compared to the feed check, Brier.Key words: Hordeum vulgare L., barley (six-row spring feed)

Johnston, a six-rowed feed spring barley (Hordeum vulgare L.) was developed at the Agriculture Canada Research Station, Brandon, Manitoba from a cross involving Klondike, Bonanza and Nord. It has high yield potential across the Canadian prairies, particularly in parts of Alberta, resistance to scald (Rhynchosporium secalis), and excellent field leaf disease ratings.

Bridge is a two-rowed, hulled, spring feed barley suitable for growing in the western part of the Canadian prairies. It has a combination of high yield potential, high test weight and large kernels. Bridge was developed from a backcross involving TR 521 (Zephyr/Hector) as the cytoplasm donor and recurrent pollen parent, and TR 516 (Betzes/Piroline *2//Zephyr). Key words: Hordeum vulgare L., barley (two-rowed spring feed)

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.

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. Key words: Hordeum vulgare L., mixtures, yield, quality, stress tolerance

Crops produced in the semiarid environment of western Canada are subjected to variable and unpredictable periods of drought stress. The objective of this study was to determine the inter-relationships among yield components and grain yield of winter wheat (Triticum aestivum L) so that guidelines could be established for the production of cultivars with high yield potential and stability. Five hard red winter wheat genotypes were grown in 15 field trials conducted throughout Saskatchewan from 1989–1991. Although this study included genotypes with widely different yield potential and yield component arrangements, only small differences in grain yield occurred within trials under dryland conditions. High kernel number, through greater tillering, was shown to be an adaptation to low-stress conditions. The ability of winter wheat to produce large numbers of tillers was evident in the spring in all trials; however, this early season potential was not maintained due to extensive tiller die-back. Tiller die-back often meant that high yield potential genotypes became sink limiting with reduced ability to respond to subsequent improvements in growing season weather conditions. As tiller number increased under more favourable crop water conditions genetic limits in kernels spike−1 became more identified with yield potential. It is likely then, that tillering capacity per se is less important in winter wheat than the development of vigorous tillers with numerous large kernels spike−1. For example, the highest yielding genotype under dryland conditions was a breeding line, S86-808, which was able to maintain a greater sink capacity as a result of a higher number of larger kernels spike−1. It appears that without yield component compensation, a cultivar can be unresponsive to improved crop water conditions (stable) or it can have a high mean yield, but it cannot possess both characteristics. Key words: Triticum aestivum L., wheat, drought stress, kernel weight, kernel number, spike density, grain yield
