Barley genetic variation: implications for crop improvement.
Genetic variation is crucial for successful barley improvement. Genomic technologies are improving dramatically and are providing access to the genetic diversity within this important crop species. Diverse collections of barley germplasm are being assembled and mined via genome-wide association studies and the identified variation can be linked to the barley sequence assembly. Introgression of ...
متن کاملAccessing genetic diversity for crop improvement.
Vast germplasm collections are accessible but their use for crop improvement is limited-efficiently accessing genetic diversity is still a challenge. Molecular markers have clarified the structure of genetic diversity in a broad range of crops. Recent developments have made whole-genome surveys and gene-targeted surveys possible, shedding light on population dynamics and on the impact of select...
متن کاملGenetic Basis of Crop Improvement
Revolutionary discoveries in biology in the 1970’s and 1980’s fueled predictions of dramatic changes in agriculture and stimulated entrepreneurial excitement and investment. Driven by continuing advances in knowledge, technology, and commercial experience, these predictions are now being realized in the marketplace. Beginning in 1994, the first wave of products from biotechnological application...
متن کاملNatural genetic variation for improving crop quality.
The narrow genetic basis of many crops combined with restrictions on the commercial use of genetically modified plants, has led to a surge of interest in exploring natural biodiversity as a source of novel alleles to improve the productivity, adaptation, quality and nutritional value of crops. Genetic methodologies have been applied to natural variation to improve quality aspects that are assoc...
متن کاملGenetic and Phenotypic Variation for Flowering Time Genes in Barley (Hordeum vulgare)
Objective: Flowering Time (FT) in cereals controlled by genes that had a main factor on plant development. Methods: Genetic and phenotypic diversity of four flowering time genes (FT2, FT3, FT4, Ppd-H1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. Genotypes based on days to flowering time and molecular data were grouped into earl...
