“…Our results of seed-coat color and eye pattern are in agreement with Drabo et al [51] who evaluated populations segregating for seed color and seed eye pattern. The results they obtained were basically supporting the findings reported by earlier researchers [24].…”

Gamma radiation is a very effective tool for inducing genetic variation in characters of many plants. Black seeds of M2 mutant were obtained after exposure of an Egyptian cowpea cultivar (Kaha 1) to a low dose of gamma rays. Segregation of seed coat color, weight of 100 seeds and seed eye pattern of the black seeds of this mutant line were further examined in this study. Four colors were observed for seed coat in the M3 plants ranging from cream to reddish brown and three eye patterns were distinguished from each other. SDS–PAGE of the seed storage proteins showed 18 protein bands; five of these bands disappeared in the seeds of M3 plants compared to M2 and M0 controls while other 5 protein bands were specifically observed in seeds of M3 plants. PCR analysis using twelve ISSR primers showed 47 polymorphic and 8 unique amplicons. The eight unique amplicons were characteristic of the cream coat color and brown wide eye pattern (M03-G10) while the polymorphic bands were shared by 6 coat-color groups. A PCR fragment of 850 bp was amplified, using primer HB-12, in M3-G04 which showed high-100 seed weight. These results demonstrated the mutagenic effects of gamma rays on seed coat color, weight of 100 seeds and eye pattern of cowpea M3 mutant plants.

“…The results of the present investigation are in agreement to the findings of Kehinde (2000). However, Drabo et al (1988) reported Non-significant at 5 per cent (P 0.05 = 7.815) level of significance five (R, P, B, M, N) major genes control seed coat colour in cowpea.…”

An investigation to study the genetics of seed related attributes was undertaken in cowpea. Three crosses (GC 2 x PGCP 5, GC 2 x PGCP 13 and GC 516 x PGCP 1) along with its parental seed, F 2 , BCI and BCII made the complete set of six generations (P 1 , P 2, F 1 , F 2 , BCI and BCII) for genetic analysis. The experiment was laid out in a Compact Family Block Design with three replications during kharif 2011. A single replication comprised of one row of parents and F 1 , two rows of the backcrosses generations, BCI and BCII and four rows of the F 2 . Genetics of seed related attributes, viz., flower colour, seed colour, seed surface, pod beak colour, calyx pigmentation and pod colour at maturity, were studied following Chisquare test of statistical significance. The results evident that flower colour in all the three crosses studied appeared to be controlled by single gene inheritance with violet flower colour dominant over white flower colour. Similarly, seed surface, pod beak colour and calyx pigmentation also appeared to be controlled by single gene inheritance, in which smooth seed surface dominant over rough seed surface, green pod beak colour dominant over red pod beak colour and green calyx pigmentation dominant over red calyx pigmentation. The inheritance of seed colour and pod colour at maturity appeared to be controlled by two gene interactions with supplementary gene action, with dominance of black seed colour over brown and white seed colour, and black pod colour dominant to red and brown colour. Dominance expression of different characters could be utilized as a good marker for different breeding activities.

“…In a series of F2 populations Spillman (1911) and Harland (1919, 1920) identified genetic factors responsible for color expression, including “ Color Factor ” ( C ), “ Watson ” ( W ), “ Holstein-1 ” ( H-1 ), and “ Holstein-2 ” ( H-2 ). A three-locus system controlling seed coat pattern was established by Spillman and Sando (1930) and was confirmed by Saunders (1960) and Drabo et al (1988), though “ O ” was used in place of “ C .”…”

The appearance of the seed is an important aspect of consumer preference for cowpea (Vigna unguiculata [L.] Walp.). Seed coat pattern in cowpea has been a subject of study for over a century. This study makes use of newly available resources, including mapping populations, a reference genome and additional genome assemblies, and a high-density single nucleotide polymorphism genotyping platform, to map various seed coat pattern traits to three loci, concurrent with the Color Factor (C), Watson (W), and Holstein (H) factors identified previously. Several gene models encoding proteins involved in regulating the later stages of the flavonoid biosynthesis pathway have been identified as candidate genes, including a basic helix–loop–helix gene (Vigun07g110700) for the C locus, a WD-repeat gene (Vigun09g139900) for the W locus and an E3 ubiquitin ligase gene (Vigun10g163900) for the H locus. A model of seed coat development, consisting of six distinct stages, is described to explain some of the observed pattern phenotypes.
