1S00:Self Colored
2W31:Watson blotcheddilute blotches are much less pronounced. Flowering pigment pattern is 4
3N40:Narrow EyeHilum ring Eye fills the narrow groove(G.) around hilum(H.) & spills out of this G in front of the H for a short distance & presents an indistinct margin in front
4H48:holstein 40 to 60spotted keel. Similar to H40 with splashes of pigment on keel joining with the pigment of the eye
5H30:Large eye to holsteinsimilar to H11 but splashes of pigment spilling over in front of hilum: the splashes having a distinct margin
6A41:restricted hilum ringsimilar to A40 but flower pigment pattern is 3.
7H38:Large eye to holsteinspotted keel. similar to H30 but with splashes of pigment on keel
8A61:Similar to A60 but flower pigment pattern is 5.
9W11:Normal Watson
10E10:Small eyeEye encircles the back of hilum(H.) in a narrow ring:widens slightly at the sides of H. & extends in a straight
11A60:the eye fills the narrow groove all around the hilumsimilar to Kabba (K) group but no specks on body. flower pigment pattern is 1
12A20:line by hilum (H)straight:narrow band of pigment on each side of H: similar to E10 but pigment does not extend completely behind H.
13A40:small hilum ringsimilar to N40 but eye more restricted in front of hilum.flower pigment pattern is 1.
14W30:Watson blotchedLarge blotches of pigment from eye move onto body
15W35:Watson speckledSpeckling tends to occur in blotches
16N41:Hilum ringspecks similar to N40 but with specks distributed uniformly over body.
17E30:Small eye-largesimilar to E10: but eye at sides of the hilum is wider than that of E10.
17E58:Broad eyespotted keel.similar to E40 but with spotted keel.
18H60:holstein 60 to 80lPigment extends out in front of hilum from the large eye and covers 60-80% of the seed.
19A10:Eye absent
20W55:Watsonnearly self colored. Eye covers almost entire seed except for small portion of micropylar end.
21K10:Densely speckledspeckles uniform over body
22A70:eye starts in a groove at either side of the hilum and spills out slightly in front of itflower pigment pattern is 1.
23K20:Lightly speckledspeckles uniform over body
24N80:Hilum ringspeckled keel. similar to N40 but with specks predominantly on keel.
25H28:Large eyespoted keel: dilute. Similar to H18 but with flower pigment pattern 1
26H11:Large eyeHeart shaped eye: with indentation at front of hilum
27H40:holstein 40 to 60pigment extends out in front of hilum from the large eye and covers 40-60% of seed
28W15:Watson with dark or speckled body
28E50:Broad eyeeye is triangle:with the hilum inside: the front of the hilum resting on the base of the triangle
29W20:Watson diluteThe margin in front of the hilum becomes more restricted
30H80:holstein 80 to 95Pigment extends out in front of hilum from the large eye and covers 60-80% of the seed.
31K30:Very Lightly speckledspeckles uniform over body
32N44:Undefined
33A42:limited hilum ringsimilar to A40. differentiated definitely by crossing.
34N84:Hilum ringlightly speckled keel. similar to N80 but with specks less dense.
35K38:speckled keel.
36A81:A thin line of pigment starts at back of the hilum (h) and moves along each side of it.A narrow clear space found b/w eye & H. Flower pigment pattern is 6.
37A85:similar to A81 but body is dark.
38H18:Large eyespotted keel. Similar to H11 but with spotted keel
39H29:Very Large eyea large semi-circle of pigment almost covering each half of the seed: with the center of the beans of each semi-circle at the hilum
40K10:densely speckledspeckles uniform over body
41H20:Large eyedilute. Similar to H11 but with flower pigment pattern 1
