Grain Sorghum Field Emergence and Seed Vigor Tests
Poor emergence of sorghum [(Sorghum bicolor (L) Moench] affects the stand and potential yields. The major objective of this research was to find correlations among field emergence data and laboratory seed vigor tests. Thirty-two and 30 hybrids of sorghum were planted at three Virginia locations in …

Inheritance of Cold Temperature Emergence in Soybeans and Its Relationship to Field Emergence and Seed Yield of Early Planted Soybeans (Heritability, Genetic, Vigor)
… Such exposure can result in decreased emergence, reduced seedling vigor, increased incidence of disease, and lowered yields. Soybean genotypes with superior cold temperature emergence (CTE) ability will avoid these problems.

Development of New and Alternative Resources for Breeding Low Phytate Soybeans
… to association with reduced seed germination and field emergence potential, low phytate (LP) soybean cultivars are not being advanced to commercialization. Soybean breeders of LP lines must adjust their techniques and resources in order to efficiently select LP germplasm. Reduced seed germination …

A Survey of the Agronomic and End Use Characteristics of Low Phytic Acid Soybeans
… However, LPA soybean lines often exhibit low field emergence making them commercially inviable. The cause of this phenomenon is widely debated with possibilities ranging from increased disease pressure to decreased seedling vigor. The objectives of this research were to 1) enhance field …

Cell cycle parameters and sweet corn emergence and seedling vigor
… endosperm mutation are associated with reduced emergence and poor seedling vigor. Shrunken2 genotypes with known differences for field emergence and vigor were used to investigate the contribution of seedling cell division to emergence and seedling growth. Variation among genotypes was observed …

Linking germination traits of oilseed rape (<i>Brassica napus</i> L.) to DNA markers
… weed in arable rotations and a feral plant of field margins, soil dumps and roadsides. Seed persistence in the soil following induced secondary dormancy is thought to perpetuate these weed and feral populations. Potential variation between cultivars has been suggested in previous work in the …

Epistasis and Other Factors Influencing the Detection of Marker-Qtl Associations
… six marker loci associated with QTL influencing field emergence and eating quality uncovered in previous studies were subjected to a second cycle of pedigree breeding. Only two of the fourteen marker-QTL associations were consistent across two cycles of pedigree selection. The lack of the …

LOW-PHYTATE GRAINS TO ENHANCE PHOSPHORUS SUSTAINABILITY IN AGRICULTURE: GENETIC ANALYSIS ON THE LOW PHYTIC ACID1-1 MAIZE MUTANT
… in this mutant. Method: In this work, a field experiment to study seed weight and yield was conducted for two years in two different genetic backgrounds (B73 and B73/Mo17). Furthermore, the greater susceptibility of lpa1-1 to drought stress was also investigated: a dedicated field …

Effects of maturity and seed size on seed vigor and plant growth in snap bean (Phaseolus vulgaris L.)
… seed size can affect seed vigor. Greenhouse and field studies were conducted to determine the effect of seed maturity on seed vigor, storability, and subsequent plant growth of four cultivars of snap bean (Topcrop, Provider Black, Provider White, and Cherokee Wax). Seeds harvested between …

Studies on the Subterranean Activity of Laricobius spp. (Coleoptera: Derodontidae) using 3D X-ray Analysis and Three Imidacloprid Soil Application Techniques
… both 2020 and 2017 resulted in above average field emergence of beetles in 2021 and 2022, with relatively insignificant residue quantities present. This study suggests that the soil injection treatment method provides a lower level risk of metabolite exposure to Laricobius spp. compared to …
