Little information is available on the response of high test-weight triticales to seeding rate in short-season growing areas. The objective of this research was to determine the effects of seeding rates of 212–307 seeds m−2 (95–138 kg ha−1) on me agronomic response of Wapiti, the first spring triticale (× Triticosecale Rimpani Wit.) registered in western Canada having a high test weight. Field tests were conducted from 1988 to 1990 at six sites in central Alberta (Botha, Drumheller, Lacombe, Olds, Provost and Trochu). Grain yield was positively related to seeding rate, with a 0.371 ha−1 increase between the lowest and highest rates tested. Test weights and protein content of the grain were affected by seeding fate but no consistent trends were established. Effects of seeding rate on days to anthesis were small (< 0.5 d) and would not be of great concern. Days to maturity responded with a significant quadratic effect, with lateness being associated With the lowest seeding rate. Seeding rate had a negative but linear association with spikelets spike−1, florets spike−1 and kernels spike−1. Only at Lacombe was a reduction in florets spikelet−1 detected with high seeding rates, while at Provost the opposite was found. Kernel weight, plant height, kernels spikelet−1 and floret fertility were not affected by seeding rate. Kernel quality was not negatively affected by the higher seeding rates. Therefore, the recommended seeding rates of Wapiti could be raised from 180–250 seeds m−2 (80–110 kg ha−1) to 270–300 seeds m−2 (120–140 kg ha−1).

The response of ‘Florico,’ ‘Victoria,’ and 'Stan II’ triticale to 2,4-D, dicamba, 2,4-D plus dicamba, diclofop, and thifensulfuron plus tribenuron applied POST during the tillering stage was examined. At rates twice those recommended for application to wheat, Victoria and Stan II were not injured, and injury to Florico was less than 10%. None of the herbicides or combinations adversely affected plant height at maturity, tiller or spike production, grain weight/spike, kernel weight, kernels/spike, yield, or test weight of any cultivar. Cultivars varied in tiller production, height, yield, test weight, kernel weight, and kernels/spike.

Days To Maturity

Malting barley is important in western Canada, yet many malting cultivars do not meet malt quality standards, in part due to lodging. Lodging can decrease barley yield and quality thereby reducing the acceptability for malting. In other countries, plant growth regulator (PGR) applications are used to mitigate lodging. Chlormequat chloride (chlormequat), trinexapac-ethyl (trinexapac), and ethephon were tested at five locations over 3 yr in western Canada for their ability to limit lodging, as well as their effects on yield, agronomic traits, and pre-malt quality characteristics. PGR applications occurred between Zadoks growth stage (GS) 30–33 for chlormequat and trinexapac and GS 37–49 for ethephon. Seeding rates of 200, 300, and 400 seeds m−2 of CDC Copeland barley were used to increase the likelihood of lodging. Increased seeding rate decreased tillers per plant, height, days to maturity, kernel protein, and kernel weight. Ethephon increased the number of tillers per plant and decreased plant height, kernel plumpness, and kernel weight. Trinexapac decreased plant height and kernel weight. Days to maturity was investigated across site-years, with ethephon increasing maturity in 60% of comparisons. Trinexapac and chlormequat had limited effects on maturity. Lodging was investigated across site-years, with trinexapac showing the largest number of lodging reductions and scale of reductions. Ethephon reduced lodging in 36% of comparisons, while chlormequat had inconsistent effects. None of the products affected yield or grain protein. The results suggest PGRs may not be the solution to lodging for CDC Copeland barley on the Canadian Prairies; however, trinexapac shows the most promise of the products tested.

Three cultivars of wheat (Triticum aestivum L. em Thell.), Glenlea, Pitic 62 and Neepawa, were grown in a seeding rate and row spacing experiment at two locations in 1972 and 1973. In a split-plot design, row spacings of 15, 23 and 30 cm were used as main plots, and subplot seeding rates of 33.6, 67.3 and 100.9 kg/ha were applied for each cultivar. Data were collected on yield, days to maturity, plant height, lodging, kernel weight and test weight. The few significant effects of row spacing indicated that narrow row spacings tend to increase yield and decrease days to maturity. Higher seeding rates per unit area generally resulted in higher yields for all cultivars and, to some extent, earlier maturity. Glenlea wheat seeded at 100.9 kg/ha gave the highest yield in all tests, and at this seeding rate took an average 125 days to reach maturity, compared to 120 days for Neepawa and 129 days for Pitic 62. Seeding rate had virtually no effect on height, kernel weight or test weight of any of the wheats.

Two spring triticale (X-Triticosecale Wittmack) cultivars, Carman and Welsh, and one advanced-generation breeding line were grown under field conditions for 3 yr to study the effects of harvest time and drying method on quality and grade. Plots were harvested at six to seven intervals when kernel water concentration was in the 1000 to 100 g water per kilogram kernel dry weight range. Grain was dried in the field in simulated windrows or artificially dried in a forced-air oven at 40–45 °C. Test weight, 1000-kernel weight, falling number, germination, and commercial grade were determined. Test weight increased with decreasing kernel water concentration at harvest, particularly in the artificially dried treatment. Test weight was greater in the windrowed than in the artificially dried treatment, especially for harvests made at high water concentrations. Harvest at high kernel water concentrations tended to reduce 1000-kernel weight, more so in the windrowed than in the artificially dried treatment. Although falling numbers were influenced by harvest time and drying method, there were no clear trends. Germination was reduced in material cut at a kernel water concentration above 680 g∙kg−1 in 1 of 2 years. Grades were reduced by artificial drying of grain, particularly when harvested at high kernel water concentrations. Grades were unaffected by windrowing at kernel water concentrations of up to 1000 g∙kg−1.Key words: X-Triticosecale Wittmack, test weight, falling number, germination, windrow

Cephalosporium Gramineum

Cephalosporium stripe (caused byCephalosporium gramineum) can be a serious disease of winter wheat (Triticum aestivumL.) in the Pacific Northwest of the USA. Effects of Cephalosporium stripe on yield, test weight, protein, and kernel characteristics were examined using 12 winter wheat varieties in field plots inoculated and not inoculated with the pathogen. Averaged over varieties, inoculation decreased yield, test weight, kernel weight, and kernel diameter; grain protein and the standard deviations of kernel weight and kernel diameter were increased by inoculation. Grain yield of the susceptible check was reduced by as much as 41% with addition of inoculum. The most resistant and the most susceptible varieties performed similarly for yield in the two environments, while varieties with intermediate levels of resistance were sometimes inconsistent. There was a linear relationship between yield and % whiteheads (sterile heads caused by disease) in one environment and a curvilinear relation in the other.

Yield Test

A study was initiated in 1990 to determine the genetic variation and adaptation of all registered Canadian barley (Hordeum vulgare L.) cultivars. Seventy-six cultivars were tested at four locations across Canada (Charlottetown, Ottawa, Brandon, and Bentley) in 1991 and 1992. These cultivars were grouped into 10 classes and classes were compared in five categories: eastern vs. western, doubled-haploid (DH) vs. conventional, feed vs. malting, two-row vs. six-row, and hulless vs. covered. These 76 cultivars showed remarkable variation in yield, test weight, kernel weight, plant height, and maturity and responded differently to the environments. Among them, Albany and Chapais had the highest yield and they also yielded well in both Eastern and Western Canada. Thus, some barley cultivars were widely adapted across the whole country. Two-row cultivars had higher test weight and higher kernel weight than six-row and appeared to be more stable in yield over the environments. Eastern two-row cultivars were superior in yield, test weight, and kernel weight than western two-row. Eastern two-row, in general, performed well across Canada. Several western six-row cultivars performed well in both Western and Eastern Canada. Therefore, greater exchanges of breeding materials between the two regions are recommended in order to fully exploit the genetic potentials of new cultivars. DH cultivars yielded as well as conventional cultivars and responded similarly to the environments. This substantiates that complete homozygosity and homogeneity have very little effect on the performance of DH cultivars. Among the western two-row, feed cultivars yielded either higher than or the same as malting cultivars in the eight environments. Hulless cultivars had lower yield, higher test weight and lower kernel weight than covered cultivars. Key words: Barley, Hordeum vulgare, cultivar, yield, adaptation

The relationships between telomeric heterochromatin on rye (Secale cereale L.) chromosomes, the occurrence of aberrant endosperm nuclei early during endosperm development, and kernel characteristics as seen at maturity were investigated in hexaploid spring triticale (× Triticosecale Wittmack). A positive relationship was established between the presence of telomeric heterochromatin on the short arms of rye chromosomes 4R/7R and 6R, and the production of aberrant endosperm nuclei. The removal of telomeric heterochromatin blocks from either 4R/7R or 6R significantly reduced the occurrence of nuclear instability in endosperm, and the effect of losing more than one block of telomeric heterochromatin was additive. A strong relationship was also noted between the absence of telomeric heterochromatin blocks on the short arms of rye chromosomes 4R/7R and 6R, and both higher thousand kernel weight and test weight at maturity. This relationship was also additive depending on whether one or two blocks of telomeric heterochromatin were missing. The absence of telomeric heterochromatin blocks on 4R/7R and 6R was significantly related with increased yield. The results show that amount of telomeric heterochromatin on some rye chromosomes is closely related to the occurrence of aberrant endosperm nuclei early during endosperm development and kernel characteristics at maturity.
