Genome-wide comparative analysis of flowering-related genes in arabidopsis, wheat, and barley
Download2015
Hu, Zhiqiu, Yang, Rong-Cai, Peng, Fred Y.
Early flowering is an important trait influencing grain yield and quality in wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) in short-season cropping regions. However, due to large and complex genomes of these species, direct identification of flowering genes and their molecular...

Beres, Brian L., Cárcamo, Héctor A., Weaver, David K., Dosdall, Lloyd M., Evenden, Maya L., Hill, Bernard D., McKenzie, Ross H., Yang, Rong-Cai, Spaner, Dean M.
The wheat stem sawfly(Cephus cinctus Norton [Hymenoptera: Cephidae]) is a serious threat to wheat (Triticum aestivum L.) and other cereal grains in the northern Great Plains. Insecticides have proven ineffective for sawfly control and can be detrimental to beneficial insects. The management of...

Management practices for carnival-season production of immature field corn in Trinidad & Tobago
Download1997-01-01
Spaner, Dean, Mather, Diane E., Brathwaite, R. A. I.
Immature field corn (Zea mays L.) grown for pre-lenten carnival festivities in Trinidad and Tobago can be a profitable cash crop. Hybrid and local unimproved open-pollinated corn were grown with two levels of weed control and fertilizer application late in the rainy season at two locations each...

Introduction: The foundation of genetics as a scientific field at the beginning of the twentieth century was not free from controversy. It meant no resolution that the advocates of the Biometric and the Mendelian schools agreed in one thing: the inheritance laws Mendel inferred by studying...

Performance and stability of performance of spring wheat variety mixtures in organic and conventional management systems in western Canada
Download2009
O'Donovan, John T., Navabi, Alireza, Kaut, A. H. E. E., Spaner, Dean, Mason, Heather E.
Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining and stabilizing yield for both organic and conventional producers. The present study examined the responses of three Canadian western red spring wheat varieties in sole crop and in variety...

Suitability of felt traps to monitor oviposition by the cabbage maggot (Diptera: AnthomyiidaeC)
Download2002-01-01
Dixon, Peggy L., West, Robert J., McRae, Ken B., Spaner, Dean
The effectiveness of felt egg traps to detect oviposition by the cabbage maggot, Delia radicum (L.), was studied under field conditions for cabbage, Brassica oleracea L. var. capitata L. (Brassicaceae), and rutabaga, Brassica napus L. var. napobrassica (L.) Reichenb. (Brassicaceae), in 1994 and...

Undersowing rutabaga with clover: Impact on Delia radicum (Diptera: Anthomyiidae) and its natural enemies
Download2004
Coady, Juanita R., Larno, David J., Dixon, Peggy L., Spaner, Dean
The cabbage maggot, Delia radicum (L.), is a serious pest of cruciferous crops in temperate regions of North America and Europe. The effects of undersowing rutabaga, Brassica napus L. subsp. rapifera Metzg. (Brassicaceae), with white clover, Trifolium repens L. (Leguminosae), on second-generation...
