Abstract:
We previously identified fs10.1 as a major QTL controlling fruit shape (index of length to width) in an interspecific F 2 cross of Capsicum annuum (round fruit) × C. chinense (elongated fruit) in pepper. To more precisely map and characterize the QTL, we constructed near-isogenic lines for fs10.1 and mapped it in a BC 4F 2 population. In this population, fs10.1 segregated as a Mendelian locus and mapped 0.3 cM away from the closest molecular marker. We further verified the effect of fs10.1 in an F 2 population from an independent cross between elongated- and conical-fruited parents. To identify additional allelic variation at fruit shape loci, we screened an EMS-mutagenized population of the blocky-fruited cv. Maor and identified the mutant E-1654 with elongated fruit. This fruit shape mutation was mapped to the fs10.1 region and was determined to be allelic to the QTL. By measuring fruit shape of near-isogenic lines for fs10.1 during fruit development, we found that the shape of the fruit is determined primarily in the first 2 weeks after anthesis. Histological measurements of cell size and cell shape in pericarp sections of fruits of the isogenic lines throughout fruit development indicated that the shape of the fruit is determined primarily by cell shape and that the development of fruit shape is correlated with cell shape. © 2011 Springer-Verlag.
