increase the selection efficiency. Genetic linkage maps that are essential to the detection of QTL and other applications have been constructed for nearly all economically important plants. Although there are a number of genetic maps reported in B. rapa

framework genetic linkage map has been constructed based on single-dose restriction fragments (SDRFs) ( Bethel et al., 2006 ). SDRFs or alternatively single-dose amplification fragments markers ( Stein et al., 2007 ) are present as a single copy on a single

inbred lines, like F 2 , BC 1 , or RILs. For this reason, yellow passion fruit linkage maps were generally constructed using a strategy known as two-way pseudo-testcross ( Grattapaglia and Sederoff, 1994 ), based on monoparental dominant markers

Genetic linkage mapping has historically been the basis for genomic investigation and the analysis of quantitative trait loci (QTL) ( Doerge, 2002 ). The construction of a detailed linkage map is, in fact, the initial step for the use of genetic

bp ( Arumuganathan and Earle, 1991 ); genetic polymorphism ranges from 10% to 15% ( Staub et al., 1997 ) and genomic length is 2276 to 3250 cM ( Staub and Meglic, 1993 ). Pitrat (1991) developed a classical melon linkage map consisting of 28

). Given that such inheritance can be traced in a genetic map that has been constructed based on linkage with the recombination rate, the genetic map is a solid foundation for genetic improvements in crop plants. More importantly, a consensus genetic map

have made it possible to create genetic maps and exploit genetic linkage between markers and traits with unprecedented resolution. For example, SNPs identified by high-throughput sequencing serve as markers of the associations between genotypes and

ancestors ( Levi et al., 2001a , 2001b ). A set of DNA markers representing different linkage regions of the watermelon genome and producing sufficient polymorphism among genotypes is needed in breeding programs aiming to produce elite triploid (seedless

availability of the whole genome sequence in cucumber provides a platform for the development of codominant markers ( Huang et al., 2009 ). A high-resolution simple sequence repeat (SSR)-based linkage map was developed using the recombinant inbred line (RIL

, we mined the ‘Jefferson’ genome sequence to develop new polymorphic SSR markers with repeat motifs of 4, 5, or 6 bp and further saturated the reference hazelnut genetic linkage map. Materials and Methods Plant material. A set of 48 diverse hazelnut
