Development of the Botanical Accessions Records System
… A model standardized system called the Botanical Accessions Records System, BARS, is described. Since records are supportive of most activities in botanical gardens and arboreta, improved efficiency and ability in records maintenance and management should improve the quality of record-dependent …

Classification of ornamental accessions of Miscanthus with molecular techniques
… hybrid uncertain, but the degree of diversity in accessions of the parent species in the USA is unknown, as is the relationship to other putative Miscanthus spp. Identification at the species level depends predominantly on floral characteristics, which is a major limitation for plants which may …

The potential effects of minimum wage changes on naval accessions
In 2014 and 2015, U.S. policymakers debated the potential economic impacts of raising the federal minimum wage to $15 an hour. Proponents for an increase in the minimum wage argue that it will help the economy since more people will have the ability to purchase more goods. Opponents believe that an …

Photoperiod sensitivity in tropical maize accessions, early inbreds, and their crosses
<p>Six tropical maize populations and five testers were used to characterize critical daylengths, to determine which tester reduced time to flowering when crossed to tropical populations, and to determine whether there was a population x tester interaction for genes controlling photoperiod. The six …

Genome composition of Glycine max and sequence diversity among cultivated and exotic accessions
… the genome that can distinguish between soybean accessions. The method developed in this study should be generally applicable to other lines of soybean or even in other crop plants that have a fully sequenced genome. These studies, along with others reported simultaneously, and those that will be …

Identification and genetic characterization of tobacco accessions possessing resistance to tobacco cyst nematode
… a diverse geographic array of tobacco accessions, including cultivars from several types of tobacco, flue-cured-type tobacco introductions, and wild Nicotiana species were evaluated for TCN resistance under greenhouse conditions. Inheritance of TCN resistance has been reported to be …

Biomass yield and nutritive value of Stylosanthes scabra accessions as forage source for Goats
… quantity and quality. Stylosanthes scabra (Vog.) accessions were evaluated for adaptability, agronomic performance, persistency and nutritive value in subtropical climate of Pretoria as potential forage source for ruminant animals. Several experiments (including field trials, laboratory experiment …

Evaluation and Identification of Soybean Aphid Resistance Sources and Mapping of Soybean Aphid Resistance Loci in Early Maturing Soybean Germplasm Accessions
… early maturing soybeans, 330 soybean germplasm accessions from Maturity Group (MG) I, along with 11 resistant or susceptible checks, were evaluated against soybean aphid in greenhouse by caged (no-choice) and non-caged tests. Germplasm accessions that showed resistance in these tests were then …

Genetic characterization of Theobroma cacao L Nicaraguan
… cacao L., including 60 Nicaraguan farmers accessions, was investigated using nine microsatellite (SSR) markers. Fourteen breeders accessions from Experimental Center “El Recreo”, INTA, Nicaragua, two Criollos accession from CATIE, Costa Rica, and two accessions from Ecuador were included as …

Phenotypic characterization of the Peach (Prunus spp.) collection at the National Clonal Germplasm Repository in Davis, California
… in Davis, CA. The recent repropagation of these accessions provided a unique opportunity to establish baseline data on a large set of uniformly aged trees. The growth habit of all accessions was primarily standard (55%), while open, upright, and compact forms were less common (36%, 6%, and 3% …

Genetics of the Arabidopsis Inflorescence Replacement Program
… The research presented here began by surveying accessions from a collection of geographically diverse Arabidopsis accessions. Five major phenotypic clusters within 85 accessions were identified. High heritability was seen for IRP phenotypes among the 85 genotypes. Principal component analysis …
