Polyploidy and Hybridization for Crop Improvement Taylor
Plant breeding, and therefore crop improvement, depends on genetic variation. Cross-pollinating plants that are similar cannot result in continued improvement. Cross-pollinating plants that are similar cannot result in continued improvement.... Crop Improvement Method # 4. Polyploidy : An organism or individual having more than two basic monoploid sets of chromosomes is called polyploid (Gr. Polys = many + aploos = one fold + eidos – form) and such condition is called polyploidy.

The role of Polyploidy in Crop Improvement Polyploidization and genetic Bottlenecks While the potential allelic diversity within a polyploid genome is greater than that of diploid genomes, often there exists higher levels of natural variation in related diploid species because the process of polyploid formation entailed a

The several consequences of polyploidy observed in natural populations have attracted great attention of plant breeders for the application of artificial polyploidy as a tool for crop improvement. The “gigas” effect is one of those direct consequences and, when occurring in organs of commercial interest, is a valuable feature for crop improvement.

[Annaliese Mason;] -- Many of our current agricultural crops are natural or agricultural hybrids (between two or more species), or polyploids (containing more than one genome or set of chromosomes). These include potato,

- Polyploidy, the state of having more than two sets of chromosomes, is common in flowering plants (angiosperms), including the major crops . Indeed, it is estimated that 30%–80% of the angiosperms are polyploids , and most diploid plant species, including Arabidopsis thaliana, show evidence of genome duplication in their ancestry . Polyploidy
- Abstract. Increasing crop yields to ensure food security is a major challenge. Mutagenesis is an important tool in crop improvement and is free of the regulatory restrictions imposed on genetically modified organisms.

- Polyploidy plays a major role in speciation and evolution . Polyploid crop genomes with multiple sets of chromosomes always undergo drastic changes in structure and function as a result of genetic and epigenetic changes [ 4 ].
