The Evaluation of Root System Architecture (RSA) As A New Breeding Target for Climate-Resilient Winter Wheat (Tritium aestivum L.)
… remobilization among 22 Virginia Tech-developed elite germplasm; 3) evaluate potential genetic variability for root biomass accumulation across breeding lines. Minimal genetic variation was observed for root biomass accumulation through time. Soil coring proved not to be a very effective method …

The cryopreservation of <i>Picea sitchensis </i>germplasm
… technology development is imperative such that elite germplasm can be conserved, without compromise to genetic integrity, whilst phenotypic validation of selected genotypes is undertaken.Three explant types were transferred from the Northern Research station, Roslin to the University of Abertay, …

Genetic Analysis of the Resistance of Soybean Genotypes to Sclerotinia Sclerotiorum
… of this research were to: (i) evaluate soybean germplasm to identify new genetic sources of sclerotinia stem rot resistance; (ii) determine the inheritance of field resistance to sclerotinia stem rot in a cross between the partially resistant cultivars Asgrow 'A2506' (A2506) and Novartis …

The physiology, mapping, and prediction of stable carbon isotopes: a proxy trait for water-use efficiency in maize
… large multiyear trials were planned with elite germplasm. These experiments showed moderate levels of heritability which facilitate characterizing the genetic architecture of this trait. Prior mapping attempts found regions correlated to δ13C, while multiple methods presented here did not. …

Genomic selection and quantitative trait loci mapping for Fusarium head blight resistance in wheat (Triticum aestivum L.)
… than 2 cM were obtained. The results show that elite germplasm can contribute to FHB resistance.

Variation in Drought Tolerance Attributes Among Tepary Bean (Phaseolus acutifolius) Germplasm
… superior genotypes of tepary bean. The germplasm was evaluated before and after the soil moisture stress treatment which was imposed on the trial by withholding water for 21 days. A 6 x 7 rectangular lattice design replicated three times was used for evaluating 42 genotypes. The results …

Genomic improvement of nitrogen utilization efficiency in maize
… and improve hybrid performance. Historical and elite germplasm were grown as inbreds and hybrids in highly managed multi-year field trials under varying rates of applied nitrogen. Preliminary results supported previous research demonstrating N uptake efficiency may already be optimized, but …

Evaluation of additive and nonadditive genetic variation in elite maize germplasm for root, shoot, and ear characteristics
… However, despite increasing research on public germplasm improvement, the role is stymied due to limited access to commercial quality lines and hybrids. Utilization of lines recently released from Plant Variety Protection (PVP) may be a solution. To this end, a selected set of inbred lines …
