Selected primitive and modern wheat species were evaluated on the basis of their carotenoid composition and effects of the genotype and environment on lutein using spectrometry and liquid chromatography. Carotenoids in the wheat extracts were identified and confirmed on the basis of their UV/vis and mass spectra compared with those of authentic standards.(More)
How many test locations and replications are needed in crop variety trials is a question every plant breeder has to ask. Simple formulas were developed to estimate the optimum number of replicates and test locations. The optimum number of replicates in a trial was estimated by the formula $$ {\text{N}}_{{\text{r}}} {\text{ = 3}}\left( {\sigma _{\epsilon(More)
Proteins extracted from five soybean cultivars were separated by reversed-phase (RP) and size exclusion (SE) high performance liquid chromatography (HPLC). A RP-HPLC method was developed that permits protein separation of nondefatted flours from soybean cultivars. RP-HPLC showed that protein of these cultivars could be classified into two groups, one of(More)
PURPOSE This study examined the effects of dietary soy protein (SP) lacking different storage protein subunits and isoflavones (ISF) on the abdominal fat, blood lipids, thyroid hormones, and enzymatic activities in rats. METHODS Weanling Sprague-Dawley rats (8 males and 8 females/group) were fed diets containing either 20 % casein without or with(More)
Pre-harvest sprouting (PHS) causes significant yield loss and degrade the end-use quality of wheat, especially in regions with prolonged wet weather during the harvesting season. Unfortunately, the gene pool of Triticum durum (tetraploid durum wheat) has narrow genetic base for PHS resistance. Therefore, finding out new genetic resources from other wheat(More)
PURPOSE This study examined the effect of soy proteins with depletion of different subunits of the two major storage proteins, β-conglycinin and glycinin, on hepatic lipids and proteins involved in lipid metabolism in rats, since the bioactive component of soy responsible for lipid-lowering is unclear. METHODS Weanling Sprague Dawley rats were fed diets(More)
Oat has been gaining renewed interest due to its role in human healthy diet. A field study was conducted across three diverse locations in Canada to determine N and P uptake, agronomic traits and yield performance of 10–12 cultivars under four fertilizer N rates. Our data showed that ‘SA060123’ and ‘OA1331-5’ were the highest-yielding cultivars, and(More)
