Since its introduction into the United States in the past 10 yr, soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), has been a damaging pest to soybean, Glycine max (L.) Merrill. During 2008 and 2009, fields in central and north central Iowa experienced pockets of high soybean aphid populations. Electroantennograms have shown that soybean aphid alatae are capable of detecting host ...

Short-term greenhouse studies with soybean (Glycine max cv. Bragg) were used to examine interactions between the soybean cyst nematode (Heterodera glycines) and two other common pests of soybean, the stem canker fungus (Diaporthe phaseolorum var. caulivora) and the soybean looper (Pseudoplusia includens), a lepidopterous defoliator. Numbers of cyst nematode juveniles in roots and numbers of cys...

A species of Neomegalotomus is an occasional pest of soybean [Glycine max (L.) Merrill] in the neotropics, including in Brazil. It was known as Neomegalotomus parvus (Westwood); but the discovery of the type specimen of a species described earlier requires that the name be changed to Neomegalotomus simplex (Westwood), which becomes the correct name for the soybean pest.

An investigation was carried out with the heavy metal Cobalt and legume plant soybean, in order to test the heavy metal accumulating ability of soybean. Cobalt was given to Soybean (Glycine max) plants in pot culture by soil drenching method. The accumulation and uptake of cobalt was tested from root, stem and leaves of treated plants. The results showed higher concentration (Co level (100-200 ...

Although soybean [Glycine max (L.) Merrill] grows as an inbreeding, generally homozygous, plant, the germplasm of the species contains large amounts of genetic variation. Analysis of soybean DNA has indicated that variation of RFLP (restriction fragment length polymorphism) markers within the species usually entails only two alleles at any one locus and that mixtures of such dimorphic loci acco...

Soybean (Glycine max) is a legume crop with substantial economic value, providing a source of oil and protein for humans and livestock. More than 50% of edible oils consumed globally are derived from this crop. Soybean plants are also important for soil fertility, as they fix atmospheric nitrogen by symbiosis with microorganisms. The latest soybean genome annotation (version 2.0) lists 56 044 c...

Three lethal-yellow mutants have been identified in soybean (Glycine max (L.) Merr.), and assigned genetic type collection numbers T218H, T225H, and T362H. Previous genetic evaluation of T362H indicated allelism with T218H and T225H and duplicate-factor inheritance. Our objectives were to confirm the inheritance and allelism of T218H and T225H and to molecularly map the locus and (or) loci cond...

The FLOWERING LOCUS T (FT) gene is a highly conserved florigen gene among flowering plants. Soybean genome encodes six homologs of FT, which display flowering activity in Arabidopsis thaliana. However, their contributions to flowering time in different soybean cultivars, especially in field conditions, are unclear. We employed six soybean cultivars with different maturities to extensively inves...

in order to evaluate intercropping of soybean (glycine max l. cv. jk) with sweet basil (ocimum basilicum l.) and borage (borago officinalis l.) with weed interference, an experiment was performed in randomized complete block design with 12 treatments and three replications at a field located 10 km of shirvan during year of 2011. the treatments were included 75% soybean: 25%sweet basil, 50%soybe...
