Some common methods to for crop improvement are:

1.Gene selection and introduction

2.Hybridization and production of polyploids

3.Inbreeding to produce desirable characteristic

Gene selection and introduction is a widely practised method in which desirable gene is selected from any of the other varieties and introduced into the native crop by gene introduction.
