Hybridisation Techniques In Plants. Hybridization and self-pollination are important aspects of research for the genetic improvement of crop plants. Single Cross Hybrids - Results from the cross between two pure bred lines and produces an F1 generation called an F1hybrid. In plants crossing is done by placing pollen grains from one genotype ie male parent on the stigma of flowers of other genotype ie female parent.

The mating or crossing of two plants or lines of dissimilar genotype is known as hybridization. The techniques require skilled hands since the process involves the bringing of the stigma and poller of different plants together. The chief objective of hybridization is to create genetic variation when two genotypically different plants are brought together in F 1. Hybridization is used to de velop new genotypes evaluate their performance or exploit hybrid vigor. Hybridization has played an important role in the evolution of many lineages.

Pollination is the process of reproduction in plants in which plants transfer pollen grains from anther to stigma.
On longer evolutionary time scales hybridization. The plant breeder must have a clear idea about the plants which he wants to use as parents a subject which may be called crop botany. The use of hybridization techniques in plant improvement remains a vital tool to cross species barriers and utilization of important attributes in unrelated crop plants which could not. In natural populations hybridization can act in opposition to divergence introduce adaptive varia-tion into a population drive the evolution of stronger reproductive barriers or generate new lineages. Hybridization is purposefully employed in the breeding of domesticated plants to take advantage of transient hybrid vigor move desirable variation among lineages and generate novel phenotypes. The chief objective of hybridization is to create genetic variation when two genotypically different plants are brought together in F 1.
