The objective of this study was to determine what effect adding moisture to stored grain would have on seed quality. Wheat cultivars were tempered to varying moisture levels (12.5, 13.5, 15.5 and 17.5%) and stored in polyethylene bags for 12 wk. Grains tempered to high moisture levels (15.5 and 17.5%) declined in quality during storage as indicated by decreased germination and increased electrolyte leakage of the seeds. Wheat tempered to 13.5% moisture for 12 wk did not show a deterioration in quality. Rates of water imbibition of wheat cultivars were also studied by sequentially weighing imbibing seeds. Cultivars differed significantly in their rates of imbibtion over 36 h, ranging from 18.5 to 24.25 mg g−1 h−1. Moisture uptake for the seven wheat cultivars can be estimated by the following equation[Formula: see text]where T = time (R2 = 0.96).Key words: Wheat (winter), seed quality, tempering, water-imbibition

Red Winter Wheat

Several previous studies have reported that grain yield of cereal crops was greater from multiple than from single nitrogen (N) applications. The purpose of the study was to determine the influence of the time and rate of N application on the yield and quality of hard red winter wheat grown in Ontario. One experiment was conducted in each of 2 yr using a factorial arrangement of treatments. Factors were rate of N application (40, 80, 120, 160, 200 or 240 kg N ha−1), and timing of N application (100/0/0, 75/25/0, 50/50/0 or 25/50/25 percent of the N applied at Zadok’s growth stages 22/32/45). Early N application reduced grain yield in a year of below-average precipitation, increased grain yield in a year of average precipitation, and increased straw yield in both years. Late N application increased grain crude protein concentration and harvest index in both years. Given the lack of a consistent yield increase and the added cost of application, it is unlikely that multiple N applications will be economical for hard red winter wheat production in Ontario.Key words: Triticum aestivum, intensive cereal management, yield components, wheat

Red Winter Wheat

Fundulea is a winter wheat (Triticum aestivum L. em. Thell.) with bread-making quality and high grain yield. It is moderately susceptible to powdery mildew and septoria leaf and glume blotch and is suited for production in areas of Atlantic Canada where winter survival is not a problem.

Husk Tomato

Fruit and seed productive capacity and physiological seed quality of 2 varieties of husk tomato were estimated: Jojutla and CHF1. The study was conducted in hydroponics under greenhouse, in the CUCBA-UDG, Zapopan, Jalisco. Red volcanic rock (/Tezontle) of 0.5 to 2 cm in diameter was used in 19 L polyethylene bags and Steiner's universal nutrient solution of 0.3 to 0.7 atm, depending on the stage of the plant. The production of fruit and seed and the physiological quality of the seed were estimated. The varieties Jojutla and CHF1 showed a similar behavior in the production of fruit and seed, with lower fruit yields than expected (30 ton / ha in the field) because only 3 harvests were made, looking to produce husk tomato in winter when it reaches attractive prices. The weight of the fruit was greater as cuts were made while the seed production improved by cutting, associated with a greater number of fruits, while the weight of the fruit was not related to the seed yield. The physiological quality of the seed was affected by cutting the fruit to commercial maturity even when it was left to mature in the shade.

Collections of Puccinia triticina were obtained from rust-infected leaves provided by cooperators throughout the United States and from wheat fields and breeding plots by United States Department of Agriculture–Agricultural Research Service personnel and cooperators in the Great Plains, Ohio River Valley, southeastern states, and Washington State and Idaho in order to determine the virulence of the wheat leaf rust population in 2012. Single uredinial isolates (501 in total) were derived from the collections and tested for virulence phenotype on 20 lines of ‘Thatcher’ wheat that are near-isogenic for leaf rust resistance genes. In 2012, 74 virulence phenotypes were described in the United States. Virulence phenotypes TNBGJ, TCRKG, and MBTNB were the three most common phenotypes. Phenotype TNBGJ is virulent to Lr39/41 and was widely distributed throughout the hard red winter wheat region of the Great Plains. Phenotype TCRKG is virulent to Lr11, Lr18, and Lr26 and was found mostly in the soft red winter wheat region in the eastern United States. Phenotype MBTNB is virulent to Lr11 and was also found mostly in the soft red winter wheat region. The frequency of isolates with virulence to Lr39/41, which is present in many hard red winter wheat cultivars in the Great Plains region, continued to increase. Isolates with virulence to Lr21, which is present in many hard red spring wheat cultivars, also continued to increase in frequency in the northern Great Plains region.
