what is clonal selection in plant breeding

Best answer


Clonal selection is theselection of the most desirable members of a clone for continued vegetative propagationrather than for sexual reproduction. The members of a clone keep up genetic constancy. So by clonal selection and continued vegetative propagation, the desirable qualities of plants can be maintained for long.

  • Merits and Demerits. Progeny of a single plant obtained by asexual reproduction is known as clone. A procedure of selecting superior clones from the mixed population of asexually propagating crops is referred to as clonal selection.

  • What is the difference between asexually propagated crops and clonal crops?

  • Progeny of a single plant obtained by asexual reproduction is known as clone. A procedure of selecting superior clones from the mixed population of asexually propagating crops is referred to as clonal selection. Crops which are propagated asexually or by vegetative means are known as asexually propagated or vegetatively propagated or clonal crops.

  • Which of the following methods of breeding are used for improving crops?

  • Besides clonal selection, interspecific hybridization and mutation breeding are also used for the improvement of asexually propagated crops. These methods have been successfully used in sugarcane and potato. Interspecific hybridization has been extensively used in the breeding of sugarcane.

  • How to choose a clonal strain?

  • First of all, clonal selection consists in choosing, during surveys of old vineyard plots or clone conservatories, strains whose behaviour is deemed to best meet the needs of winegrowers. After carrying out sanitary tests for the most serious virus diseases, the individuals are evaluated from an agronomic and oenological point of view.
