There is renewed interest in flax or linseed, Linum usitatissimum L., as a seed crop since it contains high ω3 oil important to healthy diets. Flax was raised widely in Kentucky (KY) prior to World War I. A study was conducted in KY to determine the

Sunflower (Helianthus annuus L.) productions reliance on a single source of cytoplasmic male sterility, PET1, derived from H. petiolaris Nutt., makes the crop genetically vulnerable. Twenty diverse cytoplasmic substitution lines from annual and peren

The single seed descent (SSD) method of inbreeding minimizes the amount of genetic sampling. The single-pod descent (SPD) and bulk methods (BM) produce redundant inbred lines that are descended from either the same F2 or F3 plant. However, for soybea

The genetic gain formula has been used to determine the best allocation of resources. The assumptions of this formula are that genotypes are selected based on the mean of data averaged across several locations within years. When plant breeders select

The grain yield and quality determine much of the value of an oat (A vena saliva L.) crop to the producer. This study investigated effects of genotype and environment on grain yield and quality. Twelve oat genotypes were grown during 3 yr at four loc

Nearest-neighbor analysis (NNA) adjusts for spatially correlated residuals, with the goal of increasing precision. The magnitude of the block x treatment interaction mean square is commonly used to evaluate the predsion of the NNA model. An alternati

Plants of sunflower (Helianthus annuus L.) which retain a green color in stems at physiological maturity are characterized as having the stay green trait. Research on inheritance of the stay green/early senescence trait may provide valuable informati

Cadmium (Cd) level in nonoilseed sunflower (Helianthus annuus L.), flax (Linum usitatissimum L.), and durum wheat (Triticum turgidum L. var. durum) grown on uncontaminated, alkaline soils has exceeded limits established in Northern Europe. Separate f

High grain protein content of durum wheat (Triticum turgidum L.) is important for improved cooking and nutritional quality. The development of a set or 'Langdon'-dicoccoides [LDN(DIC)] chromosome substitution lines offers an opportunity to develop ne
