Resistant weeds, dicamba training, new EPA rules and regulations, and ag companies being bought or merging together have been a few of the topics found in many ag media and publications this winter. In summary, things are continually changing in agriculture and will continue to change. One of those changes that many, if not all growers, have experienced is how to deal with weed resistance. ...
Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close the holes in their leaves, ...

Poor seed-set limits potential for soybean hybrid seed production. The objective of this study was to evaluate effects of different pollinators on the rate of seed set in three soybean cytoplasmic male sterile (CMS) lines, JLCMS9A, JLCMS82A, and JLCMS89A. The following five treatments were applied under net room isolation-conditions: (i) insecticide application and release of alfalfa leafcutter ...
A study was conducted to determine tocopherols concentration and stability in early maturing soybean genotypes and to determine their relationships to other important seed characteristics. Twenty soybean genotypes were grown in replicated trials in six environments of eastern Canada, and their total-, -, -, and -tocopherol ...
A number of soybean genotypes have resistance to soybean rust, but few of these have been challenged with the recently recovered U.S. isolates. The objective of this study was to evaluate known sources of soybean rust resistance against U.S. isolates of P. pachyrhizi. Twenty-eight soybean ...
Soybean [Glycine max (L.) Merr.] oil with oleic acid (18:1) content >500 g kg–1 is desirable for a broader role in food and industrial uses. Seed oil in commercially grown soybean genotypes averages about 230 g kg–1 oleic acid. Some maturity group (MG) II to V plant introductions (PIs) have elevated oleic concentrations of 300 to 500 g kg–1. ...
Soybean [Glycine max (L.) Merr.] was domesticated in China, and cultivated landraces were initially distributed throughout Asia and more recently extended to Europe and America. Previous studies of genetic diversity suggest a strong genetic bottleneck between Asian and North American soybean genetic pools. However, little is known about the potentially useful ...
Simulation studies have demonstrated that the existence of a limitation on maximum transpiration rate (TR) at high air vapor pressure deficit (VPD) in water-limited conditions could result in significant yield increases. A genotype of soybean [Glycine max (L.) Merr.] (PI 416937) has been identified both with a slow-wilting phenotype in the field and limited TR ...
Epistasis has sometimes been reported in qualitative and quantitative traits of soybean [Glycine max (L.) Merr.]. Our objective was to determine the extent to which epistasis occurred in crosses between soybean lines adapted to similar latitudes in Liaoning, China, and in Ohio, USA. We crossed ‘Tiefeng #27’ x HS97-4534 and ‘Ohio FG1’ x ‘Shennong #6’, and developed random F4–derived lines from ...
Early-maturing soybean [Glycine max (L.) Merr.] cultivars require less irrigation than full-season cultivars and may mature before drought periods most often occur in the midsouthern United States. ...
Genotypic differences for canopy wilting have been reported for soybean [Glycine max (L.) ...
The fatty acid composition of soybean [Glycine max (L.) Merr.] seed affects the flavor, nutritional value, and stability of the oil. Increasing oleic acid content in soybean oil would reduce the need for hydrogenation, a process that creates unhealthy trans fatty acids. The objective of this study was to map and confirm the areas of the soybean genome associated with oleic acid content from the ...
Soybean genotypes have primarily been evaluated for reaction to salt in the greenhouse using a labor-intensive and costly hydroponics method. ...
Soybean [Glycine max (L.) Merr.] seed produced in high-temperature, high-humidity production environments is prone to have substandard germination. ...
Bulk commodity soybean [Glycine max (L.) Merr.] can now be sourced with great specificity through rail and container purchases. The objective of this study was to determine whether analyses of farmer-grown soybean seed samples could detect significant regional differences in soybean quality traits. Through analysis of 2706 farmer volunteered soybean samples representing harvests from 2003–2005, ...
Genetic improvement in soybean [Glycine max (L.) Merr.] yield has been associated with both assimilate and N accumulation [especially from dinitrogen (N2) fixation] during the seed-filling period (SFP). Therefore, the physiological factors associated with genetic improvement may be dependent on abundant assimilate and N supply. The objectives of this study were to quantify genetic improvement in ...

This paper compares international trading patterns for canola, corn and soybean varieties prior to commercialisation of the Genetically Modified (GM) varieties with present trading patterns that include GM varieties. Any marketplace changes that have occurred are analysed to determine the cause for any market shifts. GM canola, corn and soybeans entered the marketplace successfully, but some ...
