Reaction of soybean rust-resistant lines identified in paraguay to mississippi isolates of phakopsora pachyrhizi
Phakopsora pachyrhizi is the causal agent of Asian soybean rust (ASR). Since the discovery of ASR in North America in 2004, evaluation of soybean [Glycine max (L.) Merr.] lines with U.S. isolates has become an important objective to identify resistance sources to the pathogen. In this study, 10 plant introductions (PIs) previously identified as resistant in Paraguay were evaluated using three ASR ...

Epistasis for quantitative traits in crosses between soybean lines from China and the United states
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 ...

Genetic improvement of seedling emergence of low-phytate soybean lines
Reduced seedling emergence of low-phytate (LP) soybean [Glycine max (L.) Merr.] lines with the pha1 and pha2 alleles has been a limiting factor in the development of LP cultivars. Crosses between normal-phytate (NP) and LP soybean lines have produced progeny with improved emergence. The objective of this study was to determine if LP lines with improved emergence are capable of producing progeny ...

Genotype x environment interaction and stability for isoflavone content in soybean
Isoflavones are naturally occurring compounds found in soybean [Glycine max (L.) Merr.]. Soybean isoflavone, as a quantitative trait, is subject to significant genotype x environment interaction, which makes breeding for this trait difficult. Thirty F4:7 soybean lines, derived from crosses of ‘RCAT Angora’ x CK-01 and ‘Heinong 35’ x RCAT Angora were classified within each population as high, ...

Genetic basis of the low-Phytate trait in the soybean line CX1834
The low-phytate (LP) trait in plant seeds offers important nutritional and environmental benefits for food and feed uses. Mutants with reduced phytate content are commonly produced by chemical mutagenesis, as is the case for soybean [Glycine max (L.) Merr.] line CX1834. Quantitative trait loci (QTL) for LP in CX1834 have previously been reported, however the genetic basis for this trait has not ...

Effect of maturity on seed composition in the early soybean production system as measured on near-isogenic soybean lines
The effect of maturity (time to maturity) on seed composition in soybean [Glycine max (L.) Merr.] genotypes is not well understood because maturity is generally confounded with genotypic background. Therefore, the effects of maturity on seed composition were estimated in two sets of near isogenic soybean lines (‘Clark’ and ‘Harosoy’), where the maturity of each line within a set varied, but all ...

Identification of candidate gene mutation associated with low Stachyose Phenotype in soybean line PI200508
To investigate the genetic factors underlying a major quantitative trait locus (QTL) contributing to low seed stachyose content in two separate populations derived from soybean [Glycine max (L.) Merr.] line PI200508, the recently released ‘Williams 82’ whole genome shotgun (WGS) sequence was exploited for candidate gene discovery. The physical interval containing a low stachyose QTL from PI200508 ...

Evaluation of a simple method to screen soybean genotypes for salt tolerance
Excessive salt can reduce soybean yield [Glycine max (L.) Merr.] in grower fields. Salt-tolerant cultivars are needed to prevent field yield losses where excess salt is a problem. Soybean genotypes have primarily been evaluated for reaction to salt in the greenhouse using a labor-intensive and costly hydroponics method. A reliable, inexpensive method to screen soybean lines for salt tolerance ...

Molecular mapping and confirmation of QTLs associated with Oleic acid content in N00-3350 soybean
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 ...

Pollinator effects on genotypically distinct soybean cytoplasmic male sterile lines
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 ...

Yield Data Errors Today, Yield Costs Tomorrow
Regardless of whether your yield data comes from your combine, grain cart, or from truck scales, each source has shortcomings that will not only influence your farm decisions but may also have a negative financial impact. This harvest growers will spend significant time and money chasing down accurate yield data from combine yield monitors, grain carts and/or truck scale tickets. Each of these ...

The Safety of Genetically Modified Foods Produced through Biotechnology
Executive Summary The Society of Toxicology (SOT) is committed to protecting and enhancing human, animal, and environmental health through the sound application of the fundamental principles of the science of toxicology. It is with this goal in mind that the SOT defines here its current consensus position on the safety of foods produced through biotechnology (genetic engineering). These products ...
