The soybean cyst nematode Heterodera glycines (SCN) is of major economic importance and widely distributed throughout soybean production regions of the United States where different maturity groups with the same sources of SCN resistance are grown. The objective of this study was to assess SCN-resistant and -susceptible soybean yield responses in infested soils across the north-central region. ...

Although soybean aphid (Aphis glycines) resistance is commercially available in the form of the Rag1 gene, the mechanism of this resistance is not fully understood. Amino acids are a limiting factor for aphid growth, and there is evidence that plant amino acid composition is related to aphid resistance. Antibiotic resistance like that conferred by Rag1 could be associated in part with both prot...

The peanut stunt virus (PSV) causes yield losses in soybean and reduced seed quality due to seed mottling. The objectives of this study were to determine the phenotypic reactions of soybean germplasms to inoculation with two PSV isolates (PSV-K, PSV-T), the inheritance of PSV resistance in soybean cultivars, and the locus of the PSV resistance gene. We investigated the PSV resistance of 132 soy...

level that could limit continued breeding success. Introduction of new sources of germplasm into the breeding Asian soybean [Glycine max (L.) Merr.] improvement programs pool may provide the genetic variability to permit conhave been conducted for many years almost completely independent of U.S. breeding programs. Productive, modern Asian cultivars may tinued progress in developing high yieldin...

Agricultural crops present phenological stages of less susceptibility to soil water deficit, in which the deficit irrigation management strategy can be used. In this context, objective was evaluate influence during different development three soybean cultivars edaphoclimatic conditions southern cerrado Piauí. The research conducted from September 2020 January 2021, municipality Uruçuí-PI (with ...

Florunner peanut and three soybean cultivars, Centennial, Gasoy 17, and Wright, were inoculated with 48-hour age cohorts of Meloidogyne arenari race 1 second-stage juveniles and placed in a growth chamber set to simulate early season (low temperature) and midseason (high temperature) conditions. Percentages of the initial inoculum penetrating roots 4 and 8 days after inoculation were 2-3 times ...

water and temperature are determinant factors for seed germination. both factors can, separately or jointly, affect the germination percentage and germination rate. the effect of temperature on germination and water potential on germination can often be described by the thermal time and hydrotime models, respectively. additionally, the thermal time model and the hydrotime model have been combin...

Soybean (Glycine max Merr.) is the world's most widely grown leguminous crop and an important source of protein and oil for food and feed. Soybean yields have increased substantially throughout the past century, with yield gains widely attributed to genetic advances and improved cultivars as well as advances in farming technology and practice. Yet, the physiological mechanisms underlying the hi...

Soybean a species of legume native to East Asia belonging to Fabaceae family .it is a cheap source of protein. This review article was carried out by searching studies in PubMed, Medline, Web of Science, and IranMedex databases up to 2016. Eighty three articles was found, of which 50 articles were included. The search terms were “soybean”, “therapeutic”, “pharmacological”, "Chemistry". Various ...
