CYBRIDS

 Cybrids- It is also called as cytoplasmic hybrid.  It consist of 2 protoplast one is donor and other is recipient the nuclear content is eliminated forming a normal heterokaryon while its plastome(cytoplasmic genome) or chondriome (mitochondrial genome )content are merged with the recipient. 

• Cybrids are cells  containing nuclear genome from only one parent but cytoplasm from both the parental species. The process of protoplast fusion resulting in the development of cybrid is known as cybridization.

• It possess heterozygosity of extrachromosomal genes. It may be single cell or a complete growing plant called cybrid plants.

Applications-

1.Way for those species witch don’t perform to sexual reproduction with each other, so this way provided to facilitate to make a desire species with combination of both species.
2.Production of wide range of genetic variations. 
3.Useful for sterile plants, mitochondrial gene also combined with chloroplast genes of another species.
