What will a farmer who would like to plant a certain rice cultivar for the coming season do when he or she only has a limited amount of seeds? Clonal propagation can be resorted to.
Clonal propagation is a method of multiplying rice plants from a single grain, an aged seedling or a rice stubble. This method, developed by R. H. Richharia in India, has several advantages over the conventional seed-crop multiplication:
- applicable to any rice cultivar
- ensures genetic purity of multiplied material
- could be easily adopted by farmers
- except for labor, the system entails minimum costs to farmers.
