“…The seed color trait is relatively stable and is not affected by environmental factors [49]–[51]. In other crops, the number of genes controlling the seed coat color trait is variable; for example, the seed color trait is regulated by a single gene in flax [52], watermelon [53], and lettuce [54], while two independent loci were found in lentil [55] and biennial white sweet clover [56], and at least three genes are involved in controlling the trait in pea [57] and capsicum [58].…”

Seed coat color is an important agronomic trait in sesame, as it is associated with seed biochemical properties, antioxidant content and activity and even disease resistance of sesame. Here, using a high-density linkage map, we analyzed genetic segregation and quantitative trait loci (QTL) for sesame seed coat color in six generations (P1, P2, F1, BC1, BC2 and F2). Results showed that two major genes with additive-dominant-epistatic effects and polygenes with additive-dominant-epistatic effects were responsible for controlling the seed coat color trait. Average heritability of the major genes in the BC1, BC2 and F2 populations was 89.30%, 24.00%, and 91.11% respectively, while the heritability of polygenes was low in the BC1 (5.43%), in BC2 (0.00%) and in F2 (0.89%) populations. A high-density map was constructed using 724 polymorphic markers. 653 SSR, AFLP and RSAMPL loci were anchored in 14 linkage groups (LG) spanning a total of 1,216.00 cM. The average length of each LG was 86.86 cM and the marker density was 1.86 cM per marker interval. Four QTLs for seed coat color, QTL1-1, QTL11-1, QTL11-2 and QTL13-1, whose heritability ranged from 59.33%–69.89%, were detected in F3 populations using CIM and MCIM methods. Alleles at all QTLs from the black-seeded parent tended to increase the seed coat color. Results from QTLs mapping and classical genetic analysis among the P1, P2, F1, BC1, BC2 and F2 populations were comparatively consistent. This first QTL analysis and high-density genetic linkage map for sesame provided a good foundation for further research on sesame genetics and molecular marker-assisted selection (MAS).

“…leaf shape (Mohr, 1953), dwarf (Liu and Loy, 1972), fruit shape (McKay, 1936 ;Poole and Grimball, 1945 ;Weetman, 1937), striping (Porter, 1937), rind color (Poole, 1944), flesh color (Shimotsuma, 1963), bitterness (Furusato and Miyazawa, 1957 ;Shimotsuma and Ogawa, 1960), seed coat color (Kanda, 1931), seed size (Poole, et al, 1941), disease resistance (Orton, 1907) and sex expression (Rosa, 1928). Although it appears paradoxical, seed size is an important consideration in the breeding of seedless watermelons as it affects their eating quality.The presence of empty seeds in seedless watermelons reduces their quality.…”

“…According to Kanda (1931), there were at least seven genes controlling the phenotypes of seed coat color with black dominant to all colors. A three-gene model has been proposed to control the seed coat color: r (red), w (white), and t (tan), respectively (McKay, 1936;Poole, 1941). The interaction of these genes produced six base colors: black (RR TT WW); clump (RR TT ww); tan (RR tt WW); white with tan tip (RR tt ww); red (rr tt WW); and white with pink tip (rr tt ww) (Kanda, 1931;McKay, 1936;Poole, 1941).…”

“…Watermelon exhibits a wide range of seed coat colors, commonly white, tan, brown, black, red, green, and dotted (Poole, 1941). McKay (1936) suggested that three genes determined watermelon seed coat color: r, w, and t for red, white, and tan, respectively. The interaction of the three genes produced six patterns: black (RR TT WW), clump (RR TT ww), tan (RR tt WW), white with tan tip (RR tt ww), red (rr tt WW), and white with pink tip (rr tt ww) (Kanda, 1931;McKay, 1936;Poole, 1941).…”

Seed coat color is an important trait highly affecting the seed quality and flesh appearance of watermelon (Citrullus lanatus). However, the molecular regulation mechanism of seed coat color in watermelon is still unclear. In the present study, genetic analysis was performed by evaluating F 1 , F 2 and BC 1 populations derived from two parental lines (9904 with light yellow seeds and Handel with black seeds), suggesting that a single dominant gene controls the black seed coat. The initial mapping result revealed a region of interest spanning 370 kb on chromosome 3. Genetic mapping with CAPS and SNP markers narrowed down the candidate region to 70.2 kb. Sequence alignment of the three putative genes in the candidate region suggested that there was a single-nucleotide insertion in the coding region of Cla019481 in 9904, resulting in a frameshift mutation and premature stop codon. The results indicated that Cla019481 named ClCS1 was the candidate gene for black seed coat color in watermelon. In addition, gene annotation revealed that Cla019481 encoded a polyphenol oxidase (PPO), which involved in the oxidation step of the melanin biosynthesis. This research finding will facilitate maker-assisted selection in watermelon and provide evidence for the study of black seed coat coloration in plants.
