A crop variety was developed at a research station in Dehradun (located in a temperate zone) and this variety produces round ( R R , or R r ) or wrinkled seeds ( r r ) with green ( G G or G g ) or yellow seed (g g) colour. A field test was performed with seeds from a cross between R R G G (round and green) and rrgg (wrinkled and yellow) parents. Seeds obtained from this test were planted at the same research station
