WebJun 17, 2024 · Mutagenic agents such as colchicine, oryzalin, nitroxide, and epoxomicin have been used for polyploidy induction in plants. The most frequently applied is colchicine, although it sometimes has undesirable side effects, including sterility, abnormal growth, chromosomal rearrangement or reduction, and gene mutation [37,42,43,44,45]. WebThere have also been extensive applications in the breeding of cultivated plants. One of the important events in this field was the discovery (Blakeslee and A. G. Avery, 1937) that doubling of the chromosome set in plants may be induced by the use of colchicine. Winge’s interpretation of polyploidy grew out of a comparison of the

WebIn some situations, polyploid cultures are preferred because they are sterile. For example, wide varieties of seedless fruits are seedless due to polyploidy. These crops are propagated using asexual techniques, such as grafting. Polyploidy in crop plants is often induced by treating seeds with the chemical colchicine. Examples WebBackground and Aims Polyploidy has played a major role in the origin of new plant species, probably because of the expansion of polyploid populations in the species’ ecological niche, and because reproductive isolation can be established between a new polyploid population and its diploid progenitor species.

WebPaleopolyploidy is the result of genome duplications which occurred at least several million years ago (MYA).
