Linkage Analysis of the Three Loci Determining Rind Color and Stripe Pattern in Watermelon
Yang, Hee-Bum,Park, Sung-woo,Park, Younghoon,Lee, Gung Pyo,Kang, Sun-Cheol,Kim, Yong Kwon Korean Society of Horticultural Science 2015 원예과학기술지 Vol.33 No.4
The rind phenotype of watermelon fruits is an important agronomic characteristic in the watermelon market. Inheritance and linkage analyses were performed for three rind-related traits that together determine the rind phenotype: foreground stripe pattern, rind background color, and depth of rind color. The inheritance of the foreground stripe pattern was analyzed using three different $F_2$ populations, showing that the striped pattern is dominant over the non-striped pattern. The inheritance analysis of the rind background color was performed using $F_2$ populations of the '10909' and '109905', and the depth of rind color was analyzed using $F_2$ populations of the '90509' and '109905'. Yellow color was found to be dominant over green color, and a deep color was dominant over the standard color. Linkage analysis of the three traits was conducted using three $F_2$ populations in which two traits were segregating. Each pair of traits was inherited independently, which demonstrated that the three traits are not linked. Therefore, we propose a three-locus model for the determination of rind phenotype, providing novel insight that rind phenotype is determined by the combination of three genetically independent loci.

Rapid and Practical Molecular Marker Development for Rind Traits in Watermelon
박성우,김기택,강순철,양희범 한국원예학회 2016 Horticulture, Environment, and Biotechnology Vol.57 No.4
A three-locus model for rind phenotypes in watermelon (Citrullus lanatus) was previously proposed based on genetic analysis. These three loci, S (foreground stripe pattern), D (depth of rind color), and Dgo (backgroundrind color), segregate in a Mendelian manner. Whole genome sequencing of watermelon offers a new strategy for marker development in these rind phenotype-related loci. A genotype analysis using subsets of 188, 273, 287 and113 probes was performed for the ‘0901’, ‘10909’, ‘109905’ and ‘90509’ rind trait-segregating F2 populations, respectively. A total of 26, 34, 30 and 15 linkage groups with 175, 254, 269 and 79 probes were constructed forthe ‘0901’, ‘10909’, ‘109905’ and ‘90509’ populations, respectively. The genetic order of the probes was mostly collinear with the physical order on the reference genome, except for some probes on chromosomes 1, 3 and 11. The threerind-related loci, S, D, and Dgo were anchored near chr6_25767 on chromosome 6, chr8_26061 on chromosome 8 and chr4_150/chr4_249 on chromosome 4, respectively. The three loci are located on different chromosomes, and thethree-locus model was therefore verified through molecular genetic analysis. We suggest a rapid and practical marker development strategy that can be used not only for rind traits but also for other agriculturally important traits inwatermelon and applied for conventional breeding.
