What is the Economic Importance of Polyploidy?. Successful and unsuccessful applications of polyploid induction to plant breeding are considered, using examples from a wide range of crop plants. Following an historical survey and an account of current trends in polyploid induction, information is reviewed on the conditions affecting the success of the use of polyploids in breeding, induced autoploidy and alloploidy, and induced polyploidy, The induction of polyploidy is a common technique to overcome the sterility of a hybrid species during plant breeding. For example, triticale is the hybrid of wheat (Triticum turgidum) and rye (Secale cereale). It combines sought-after characteristics of the parents, but the initial hybrids are sterile..

Introduction Polyploidy involves three or more sets of chromosomes , and may occur naturally or by induction. Nearly all plants and animals probably have some polyploid tissues. Polyploidy is most commonly observed in the plant kingdom. Thousands of years of selective cultivation and plant breeding have resulted in vigorous food plants that are commonly tetraploid and

POLYPLOIDY IN PLANT BREEDING. Polyploidy can have many effects on plants, but specific effects vary greatly from species to species, as well as from functions of gene expression, heterozygosity, ploidy level, and different traits of individual plants. The induction of polyploidy is a common technique to overcome the sterility of a hybrid species during plant breeding. For example, triticale is the hybrid of wheat (Triticum turgidum) and rye (Secale cereale). It combines sought-after characteristics of the parents, but the initial hybrids are sterile.

8/26/2011В В· Highlights We describe the overview of plant regeneration system from endosperm for producing polyploidy plants showing endosperm-ploidy level and application to plant breeding. A brief history of endosperm culture is also described. Prospects of endosperm culture are proposed for novel approaches for polyploidy breeding. Plant polyploidy is induced in the laboratory by treating dividing cells with the drug colchicine. It prevents the formation of a spindle during mitosis by disrupting the microtubules, causing the duplicated chromosomes to fail to separate. The most common method of application is to place the roots of a plant in a colchicine solution.

In the past 30 years, polyploids have been successfully identified and induced in many ornamental species. Polyploidization can not only alter plant morphology, but also change physiological and biochemical metabolisms in plants, generating new cultivars and breeding materials.
