The fine structure of plastids was studied in the course of androgenesis in in the pollen of <em>Hordeum vulgare</em> L. It was found that these organelles occur in all stages of androgenesis. Their structure was simple and was frequently manifested on the cross section only by the presence of the envelope and matrix of different degree of density. Single thylakoids, nucleoid-like regions and starch grains were, however, also noted. The structure of plastids in embryoids formed from microspores of barley was compared with embryos developed from fertilized egg cell, and we did not found any fundamental differences between them. However, only plastid ribosomes were difficult to identify on ultrathin sections in embryoids and in the embryos.

Diamond is a six-rowed feed barley (Hordeum vulgare L.) developed at Agriculture Canada Research Station, Lacombe, Alberta, from the cross Galt/Unitan. It has large kernels and yields more than other cultivars in its maturity group. Diamond has adequate disease and lodging resistance to be grown anywhere in the traditional six-rowed barley areas of Western Canada.Key words: Hordeum vulgare, barley, feed barley, cultivar description

AAC Goldman is a hulled, two-row, spring, malting barley (Hordeum vulgare L.) cultivar widely adapted to western Canada. It was developed from the cross TR04282/Newdale made in 2002 and was evaluated in the Western Cooperative Two-row Barley Registration Test (2010–2011) as well as the Collaborative Malting Barley Trials (2011–2012) conducted by the malting and brewing industry before being registered in 2018. AAC Goldman has a desirable combination of agronomic, malting quality, and disease resistance traits including low deoxynivalenol content.

Jackson (Hordeum vulgare L.) is an early-maturing, hulled, six-row feed barley. It was developed at the Northern Agriculture Research Centre, Beaverlodge, Alberta from the cross BT607/Pomo. It is short in height, moderately strong strawed, and adapted to western Alberta and the Peace River region of British Columbia.

The cross section for photoneutron production in 181Ta has been measured from threshold to 28� 8 MeV using bremsstrahlung and direct neutron detection. Integrated between these limits, the absolute value of the cross section has been determined to be 2 '47 �O' 35 MeV. b. An examination of the cross section variation with excitation energy reveals the existence of the giant quadrupole resonance lying on the high excitation edge of the dipole peak. This provides additional evidence for the validity of the dynamic collective model. The present data do not support the existence of extensive fine structure below 17 MeV, as proposed by Ishkhanov et al. (1969).

Scout is a high energy, two-rowed, hulless feed barley (Hordeum vulgare L.) developed at the Crop Development Centre, University of Saskatchewan from the cross Centennial/Fergus//Hulless Betzes. Its main attribute is its hulless nature which makes it a high-energy feedstuff. It is best adapted to the two-rowed barley areas of Saskatchewan and Alberta.Key words: Barley, Hordeum vulgare L., naked barley, energy
