    D Selection and Introduction Correct Answer Incorrect Answer

    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. Hybridization is the crossing of two varieties, species or genera having desired genes by bringing together the useful characters of these into one progeny.
