The yield of 12 spring barley cultivars (Hordeum vulgare L. and H. distichum L.) was tested under 61-cm grid, space-planted conditions and solid-seeded conditions in 1970 at two locations in Northern Alberta. A sample size of 10–20 plants was necessary to give consistent yield estimates for space-planted cultivars. Heritable differences for yield were ground in all tests, but a significant relationship between yielding ability under the two testing methods was found only at one location.

Two spring barley (Hordeum vulgare L. emend Lam.) and three spring wheat (Triticum aestivum L.) cultivars were grown over a 2-yr period at three locations in Alberta north of latitude 53°N, to compare the effect of fall and spring seeding on yield and maturity. The cultivars were Olli and Jubilee barley, and Park, Thatcher, and Pitic 62 wheat. The locations were Edmonton, Beaverlodge, and Fort Vermilion. With few exceptions, fall seeding resulted in loss of yield compared with spring seeding, and the fall-seeded materials were no earlier maturing than the comparable spring-seeded materials. For the cultivars and locations studied, fall seeding of spring barley and wheat cannot be recommended. Two spring seeding dates were also compared, the first being considerably earlier than typical commercial seeding at the same location. There were few significant differences in yield between the two spring dates, but the later date considerably delayed the maturity of all cultivars.

Seed longevity of 76 spring barley gene pool samples (Hordeum vulgare L. subsp. distichon, convar. distichon: 56 nutans Schubl., two deficience (Steud.) Koern., two erectum Rode ex Shuebl., two medicum Koern.; convar. nudum (L.) A.Trof.: one nudum L. та subsp. vulgare: convar. vulgare: nine pallidum Ser., three rikotense Regel.; convar. coeleste (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.

Freezing Chamber

Three spring barley (Hordeum vulgare L.) cultivars were planted at four seeding dates to evaluate the effect of a simulated frost at the two-leaf stage on growth and yield. A portable field freezing chamber was used to subject the plants to a − 5.6 °C stress. The frost caused 49, 64 and 68% injury to the leaves and delayed heading by 2.4, 1.4 and 2.4 days in Gait, Atlas and Olli, respectively. Frost also reduced the number of tillers per plant, ripe heads per plant and plants per plot in all cultivars. Although the late-maturing cultivar Galt had the most leaf frost resistance, the average 13.8% yield reduction within all three cultivars, owing to the freezing stress, was not significantly different between any of the cultivars. Complete defoliation by clipping resulted in no further reduction in yield than that which occurred from partial defoliation by freezing. Delayed seeding resulted in an 8.6% reduction in yield. Frost reduced the yield of early seeded cultivars by 9.8% and late-seeded cultivars by 17.1%.

Four trials with 18 triplet combinations of tall, intermediate and short cultivars of spring wheat, and four trials with 18 triplet combinations of one short and two tall cultivars of spring barley, were conducted over 3 yr at Saskatoon to test the hypothesis that differences in height would not cause interplot competition for grain yield. Significant competition between cultivars was detected in two trials with wheat and in one of the barley trials.Key words: Wheat (spring), Triticum aestivum L., barley (spring), Hordeum vulgare L., interplot competition, grain yield

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.
