iv. use of distant species to develop disease,

v. insect, pest and stress resistant varieties,

vi. methods of transferring resistance genes ‘ from wild species to cultivated varieties.


vii.selection procedure in the progenies of distant hybrids, and

viii. synthesis of new crop species.

In addition, various aspects of biotech­nology, somatic cell hybridization, molecular biology and genetic engineering for the utilization of wild species are also another aspect that deals with distant hybridization.
