2Kabba groupEye fills the narrow groove all around the hilum, and the body has some form of speckling. A blue halo is also found around the hilum, Group K
3Narrow eyeHilum Ring. Eye fills the narrow groove around the hilum and spills out of this groove in front of the hilum for a short distance and has an indistinct front margin, Group N
4Small eyeeye has a distinct margin, but is smaller than Holstein group, Group E
5Holstein groupeye encircles the back of the hilum in a narrow ring, widens at the sides, and then extends margin of the eye is very distinct, Group H
6Watson groupeye encircles the back of the hilum as a narrow ring, widens at the sides and spills over the non –micropylar end of the seed with an indistinct margin. The extra width at the sides of the hilum distinguishes this group from 3, narrow eye, Group W
