A
introduction and mutation
B
selection and introduction
C
selection and hybridization
D
mutation and selection.
Answer
selection and hybridization
Explanation
Solution
The new plant varieties are produced by selection and hybridization. Selection is a non-random process which leads to individuals of different genotypes being represented unequally in their progeny in later generations of a population of self propagating units. Selection can be natural or artificial. Hybridization is the crossing of two varieties, species or genera having desired genes by bringing together the useful characters of these into one progeny. Both , these processes produce new plant varieties.
