Introgression of Genes by Wide Hybridization: a Crop Improvement Approach
Introgression is the movement of genes or gene flow from one species into the gene pool. wide hybridisation breaks the species barrier for gene transfer and makes it possible to transfer the genome of one species to other, which results alteration in genotypes and phenotypes of the progeny. The main objective of wide hybridisation is to transfer desirable genes, to create genetic variability wh...
متن کاملApplication of Embryo Rescue Technique in Juglans regia L. x J. nigra L. Hybridization
Embryo culture were used to produce inter specific walnut hybrid plants between Juglans nigra L. and J. regia L. Developed ovaries were collected from J. rejia female flowers which were pollinated with J. nigra pollen grain by high dusting on a mature tree. In order to isolate embryos, exocarps were aseptically removed. Isolated embryos from ovules at different developmental stages were transfe...

متن کاملIn situ embryo rescue for generation of wide intra‐ and interspecific hybrids of Panicum virgatum L.
Wide crosses have been used for decades as a method for transferring novel genetic material and traits in plant breeding. Historically, many products of wide crosses require tedious and inefficient surgical embryo rescue prior to embryo abortion to recover single plantlets. We have utilized transgenic switchgrass (Panicum virgatum L. cv Alamo) as a pollen donor in conjunction with antibiotic or...
متن کاملHybridization facilitates evolutionary rescue
The resilience of populations to rapid environmental degradation is a major concern for biodiversity conservation. When environments deteriorate to lethal levels, species must evolve to adapt to the new conditions to avoid extinction. Here, we test the hypothesis that evolutionary rescue may be enabled by hybridization, because hybridization increases genetic variability. Using experimental evo...
