Reid, T.A., Cahill, J.F., Navabi, A.
Competition with weeds decreases crop yields globally. Breeding for competitive ability against elevated weed pressure can be difficult because the selection for specific traits which contribute to competitive ability may result in yield losses. The widely studied International Triticeae Mapping...

Whitehouse, C. M., Evenden, M. L., Sperling, F. A. H., Strong, W. B., Roe, A. D.
Abstract: Coneworms, Dioryctria Zeller (Lepidoptera: Pyralidae), are destructive pests of conifers across North America, and members of several different species groups present significant pest-management challenges in conifer seed orchards. Dioryctria abietivorella Grote (abietella group) is the...

Differential growth and rooting of upland and peatland black spruce, Picea mariana, in drained and flooded soils
Download2007
A reciprocal experiment was analyzed to determine whether 30 open-pollinated families of peatland and upland populations of black spruce [Picea mariana (Mill.) B.S.P.] sampled from a single area in north-central Alberta, Canada, performed consistently when grown in either flooded or well-drained...

Effect of Plant Age, Larval Age, and Fertilizer Treatment on Resistance of a cry1Ab-Transformed Aromatic Rice to Lepidopterous Stem Borers and Foliage Feeders

Rubia, L., Ghareyazie, B., Alinia, F., Bennett, J., Cohen, M. B.
Abstract: The resistance of vegetative, booting, and flowering stage plants of a variety of an aromatic rice, Oryza sativa L., transformed with a Bacillus thuringiensis Berliner cry1Ab gene under control of the maize phosphoenolpyruvate carboxylase (PEPC) promoter was evaluated against four...

Effects of Bacillus thuringiensis on non-target herbivore and natural enemy assemblages in tropical irrigated rice

Cohen, Michael, B., Gaolach, Bradley, Viagante, Vicente D., Zhang, Wenjun, Schoenly, Kenneth G., Barrion, Alberto, T.
Endotoxins from Bacillus thuringiensis (Bt) produced in transgenic pest-resistant Bt crops are generally not toxic to predatory and parasitic arthropods. However, elimination of Bt-susceptible prey and hosts in Bt crops could reduce predator and parasitoid abundance and thereby disrupt biological...

Estimation of genetic and phenotypic parameters for ultrasound and carcass merit traits in crossbred beef cattle
Download2014
Bruce, H. L., Plastow, G. S., Moore, S. S., Wang, Z., Nkrumah, D., Miar, Y., Durunna, O.
Ultrasound measurements of 852 crossbred steers along with carcass merit measurements on 756 of them were used to examine their genetic and phenotypic parameters. Traits including ultrasound backfat thickness (UBF), ultrasound ribeye area (UREA), ultrasound marbling (UMAR), carcass weight (CWT),...

Frequency of alleles conferring resistance to a Bacillus thuringiensis toxin in a Philippine population of Scirpophaga incertulas (Lepidoptera: Pyralidae)
Download2000
Cohen, M. B., Andow, D. A., Romena, A. M., Gould, F., Bentur, J. S.
Abstract: Using the F-2 screen methodology, we estimated the frequency of alleles conferring resistance to the CrylAb toxin of Bacillus thuringiensis Berliner in a Philippine population of the stem borer Scirpophaga incertulas (Walker). Evaluation of >450 isofemale lines for survival of F-2...

Goonewardene, L. A., Wang, Z., Yang, R. C., Huedepohl, C.
Data from the Alberta Agriculture Food and Rural Development data base, which keeps inventories of elk producers and velvet production information (n = 12 724), were used to estimate genetic and phenotypic variances, heritability and repeatability estimates for velvet antler using REML methods....

Dhir, N., Rweyongeza, D., Yeh, F.
We estimated heritabilities and correlations for bud flushing and growth traits of white spruce seedlings, and the correlations of seedling traits with 10- and 11-year height of the same families in the field. The seedling greenhouse experiment had a randomized complete block design with 30...

Genetic variation in height, branch and needle lengths of Pinus sylvestris L. from Siberia tested in Alberta, Canada
Download2003
Dhir, N.K., Rweyongeza, D., Yeh, F.C., Dancik, B.P.
We performed the analysis of variance and covariance on height, branch length, height to branch length ratio, and needle length measurements from thirty open-pollinated families of Pinus sylvestris L. from Siberia, Russia. This progeny trial was replicated on three sites in central Alberta,...
