| genetic basis of soybean adaptation to north american vs. asian mega-environments in two independent populations from canadian × chinese crosses. | one of the goals of plant breeding is to increase yield with improved quality characters. plant introductions (pi) are a rich source of favorable alleles that could improve different characters in modern soybean [glycine max (l.) merril] including yield. the objectives of this study were to identify yield qtl underlying the genetic basis for differential adaptation of soybeans to the canadian, united states or chinese mega-environments (me) and to evaluate the relationship and colocalization bet ... | 2013 | 23595202 |
| characterization of the genetic changes in a multi-generational pedigree of an elite canadian soybean cultivar. | genotyping through the pedigrees of elite soybean [glycine max (l.) merr.] cultivars developed by a breeding program represents an opportunity to explore and characterize various molecular and genetic changes that are a direct result of long-term selection by soybean breeders. for soybeans bred for ontario canada, one such elite cultivar was oac bayfield, which had exceptional commercial success as well as being a parent of a number of successful cultivars developed by multiple independent breed ... | 2014 | 24141573 |
| photosynthetic response of soybean to microclimate in 26-year-old tree-based intercropping systems in southern ontario, canada. | in order to study the effect of light competition and microclimatic modifications on the net assimilation (na), growth and yield of soybean (glycine max l.) as an understory crop, three 26-year-old soybean-tree (acer saccharinum marsh., populus deltoides x nigra, juglans nigra l.) intercropping systems were examined. tree competition reduced photosynthetically active radiation (par) incident on soybeans and reduced net assimilation, growth and yield of soybean. soil moisture of 20 cm depth close ... | 2015 | 26053375 |
| evaluation of sampling methodology for determining the population dynamics of onion thrips (thysanoptera: thripidae) in ontario onion fields. | onion thrips, thrips tabaci lindeman, are an economic pest of alliums worldwide. in ontario onion-growing regions, seasonal abundance and population trends of onion thrips are not well known. the objectives of this research were to investigate onion thrips population dynamics by using both white sticky traps and plant counts, to gain insight into flight height, and to determine the genus and sex of thrips fauna present in monitored fields. adult thrips were captured on white sticky traps placed ... | 2005 | 16539160 |
