Singh, S., Singh, H., Sharma, A., Meeta, M., Singh, B., Joshi, N., Grover, P., Al-Yassin, A. and Kumar, S. 2014. Inheritance of spot blotch resistance in barley (Hordeum vulgare L.). Can. J. Plant Sci. 94: 1203–1209. Spot blotch, caused by Bipolaris sorokiniana, is a major disease of barley hampering its commercial production in many parts of the world. Growing resistant cultivars is the most effective, economical and eco-friendly approach to control the disease. To understand the inheritance of resistance, F1, F2 and F3 generations of two crosses, involving susceptible (PL426 and RD2503) and resistant (BL9 and BL10) parents were studied. The susceptibility of F1 plants and a ratio of 13 susceptible:3 resistant in F2 populations in both crosses indicated that the reaction to spot blotch is hypostatic and is governed by two genes with an epistatic/inhibitory effect of first on the second one. The resistant reaction appeared due to the presence of dominant allele of the second gene. The first gene in dominant homozygous or heterozygous condition had an inhibitory effect over the second gene. The inheritance pattern was confirmed from the segregation pattern of F3 progenies of both the crosses. One hundred-fifty F2:6 recombinant inbred lines (RIL) derived from PL426/BL10 cross gave a good fit to the ratio of 1 resistant:3 susceptible lines under artificial and natural epiphytotic conditions. Recovery of transgressive segregants in the RIL population indicated the presence of some modifiers or minor genes. Test of allelism involving susceptible (PL426)×susceptible (RD2503) and resistant (BL9)×resistant (BL10) parents revealed that both the susceptible parents as well as resistant parents were allelic to each other.

AAC Vitality is a six-row spring feed barley (Hordeum vulgare L.) cultivar developed by the Eastern Cereal and Oilseed Research Centre, Agriculture and Agri-Food Canada. AAC Vitality had high grain yield, good resistance to lodging, and good resistance to straw break. It was late in heading and maturity. Its seed color was bright. AAC Vitality was moderately resistant to net blotch and spot blotch. AAC Vitality performs well in Ontario.

A simple two-step model for evaluation of in vitro regeneration protocols is proposed based on callus induction and regeneration from immature scutella of two Canadian barley (Hordeum vulgare L.) genotypes, AC Metcalfe and SB92559 using the Enhanced Regeneration System (ERS). The number of explants producing embryogenic callus, the number of plants per embryogenic callus and the number of plants per explant were considered. Tissue culture parameters included three combinations of growth regulators, two carbon sources in culture media, and three cold treatment regimes of spikes prior to scutella isolation. Culture medium containing 5 µM 2,4-dichlorophenoxy acetic acid (2,4-D) and 0.5 µM benzyl adenine (BA) induced the highest percent of embryogenic calli and the highest number of shoots per embryogenic callus from AC Metcalfe. Medium containing 3.75 µM 2,4-D and 0.75 µM BA gave the best response for SB92559. Both genotypes produced more shoots on maltose than on sucrose medium. A 2-d treatment of spikes at 4°C resulted in best response for SB92559. Regeneration response from AC Metcalfe scutella from spikes was unaffected by being subjected to 2, 4 or 6 d of cold. Conditions resulting in best responses from both genotypes were tested on four commercial barley varieties. However, these lines showed inferior regeneration compared to SB92559 and AC Metcalfe.

Rumen fluid from two sheep was used to determine in vitro dry matter digestibilities of 25 samples each from alfalfa hay (Medicago sativa L.) and barley grain (Hordeum vulgare L.). The sheep were fed either a good quality hay ad libitum and 1 kg rolled barley per day, or only the hay ad libitum, in a switchback design. The in vitro dry matter digestibilities of both alfalfa hay and barley were lower (P < 0.01) when the donor animal was fed hay and barley than when fed only hay.
