state two merits of micro popogation

Micro propagation is useful
1. For plants that are difficult to propagate by conventional methods (e.g. plants producing little viable seeds )
2. In relatively short time (due to increased multiplication rate ) and space,  a large number of plants  can be produced by
(a) Genetically stable and true-to-type progeny (by  rapid clonal propagation )
(b) Virus-free.
(c) Insect-resistant, disease-resistant, herbicide-resistant. With special phenotypic characteristic (i.e.) changed genotypes (tetraploids, haploids, and hybrids) can be produced from single individual.
