(i) some seeds float as they are damaged or hollow. this makes them light weighted and therefore float. the seeds which sink are good and healthy seeds. this method is used by farmers to select disease free, healthy seeds.
(ii) The selection of seeds is used to improve the quality of yields. There are several diseases that are transmitted via the seeds. If the selected seeds are from the infected fields then the seed-borne diseases will cause severe problems in the agricultural process. Thus, always obtain seeds from healthy plants.
