“…Liu et al (2005) reported that 413 TRAP markers were mapped in less than 3 weeks and found an average 24 polymorphic TRAP markers per PCR reaction using one fixed and two random primers. It has been shown that the TRAP markers are highly efficient in producing large numbers of polymorphic markers (Hu et al 2005;Liu et al 2005;Alwala et al 2006) and could be used to significantly increase map density by linking the linkage groups and filling gaps (Yang et al 2005). However, in this research, we were only able to obtain an average of 2.1 polymorphic TRAP loci per primer pair, due perhaps to the less sensitive silver staining method used.…”

“…By using the TRAP technique, Alwala et al (2006) and Hu et al (2005) have assessed genetic diversities of sugarcane and lettuce, respectively. Liu et al (2005) and Yang et al (2005) have constructed genetic maps in wheat including TRAP markers. Moreover, a QTL for earliness was detected that could explain 38% of the phenotypic variation peaked in the interval of the TRAP marker.…”

A high-density linkage map was constructed for an F 2 population derived from an interspecific cross of cultivated allotetraploid species between Gossypium hirsutum L. and G. barbadense L. A total of 186 F 2 individuals from the interspecific cross of "CRI 36 × Hai 7124" were genotyped at 1 252 polymorphic loci including a novel marker system, target region amplification polymorphism (TRAP). The map consists of 1 097 markers, including 697 simple sequence repeats (SSRs), 171 TRAPs, 129 sequence-related amplified polymorphisms, 98 amplified fragment length polymorphisms, and two morphological markers, and spanned 4 536.7 cM with an average genetic distance of 4.1 cM per marker. Using 45 duplicated SSR loci among chromosomes, 11 of the 13 pairs of homologous chromosomes were identified in tetraploid cotton. This map will provide an essential resource for high resolution mapping of quantitative trait loci and molecular breeding in cotton.Key words: cotton; linkage map; target region amplification polymorphism. Available online at www.blackwell-synergy.com/links/toc/jipb, www.jipb.net Genetic linkage maps based on molecular markers have become an important tool for genome analysis, detection of quantitative trait loci (QTL) underlying important traits, physical mapping, map-based cloning and marker-assisted selection. After the first molecular linkage map based on restricted fragment length polymorphism (RFLP) was reported by Reinisch et al. (1994), many maps based on RFLP, RPAD (random amplified polymorphic DNA), SSR (simple sequence repeats) and AFLP (amplified fragment length polymorphism) markers, among others, have been published for segregating populations derived mainly from interspecific (Gossypium hirsutum × Gossypium barbadense) crosses (Shappley et al. 1998; Brubaker et al. 1999; Lacape et al. 2003;Nguyen et al. 2004;Rong et al. 2004;Song et al. 2005;Guo et al. 2006).However, for comprehensive analysis of cotton genome and QTL mapping, it is essential to develop more markers and explore novel molecular marker systems. Expressed sequence tags (EST) have provided an ample source for the development of SSR markers that have been added to the existing cotton linkage maps (Park et al. 2005; Han et al. 2006;Wang et al. 2006). Sequence-related amplified polymorphism (SRAP) marker system, developed by Li and Quiros (2001), has been successfully used to construct cotton linkage maps (Lin et al. 2005;Zhang et al. 2005). Another new marker system, target region amplification polymorphism (TRAP) is also polymerase chain reaction (PCR)-based (Hu and Vick 2003) to detect EST-linked polymorphic markers, in which a fixed primer designed based High-density Linkage Map of Cotton 717 on expressed sequence tags or any cDNAs sequences is used in a PCR reaction in combination with a random primer containing either an AT-or GC-rich core sequence targeting an intron or exon. By using the TRAP technique, Alwala et al. (2006) and Hu et al. (2005) have assessed genetic diversities of sugarcane and lettuce, respectively. L...

“…del Blanco et al 2003;, other cultivars with relatively high FHB resistance come from this region, e.g. Chinese cultivars Ning 7840, Ning 894037 (Shen et al 2003a;Zhou et al 2003), Wangshuibai Jia et al 2005;Mardi et al 2005;Lin et al 2004Lin et al , 2006Ma et al 2006), Wuhan, Japanese cultivars Nobeokabozu and Nyu Bai (Nyubai) or Korean cultivar Chokwang (Yang et al 2005). Sumai 3 is a highly FHB resistant Chinese spring wheat cultivar which was derived from a cross between Italian wheat Funo and Chinese landrace line Taiwan Xiaomai Wheat.…”

The aim of this review is to summarize recent information on Fusarium head blight (FHB) in small grain cereals, especially in wheat and barley. Basic information on FHB epidemiology, types of resistance and plant resistance mechanisms is included. Standard methods for the evaluation of the individual types of FHB resistance and the extent of infection are briefly described. Special attention is paid to the sources of FHB resistance of different origin and possibility of their exploitation in cereal breeding. Unfortunately, a high level of FHB resistance was detected in non-adapted germplasm or distant relatives, which is a serious impediment to breeding progress in this field. The present state of breeding for FHB resistance in wheat, barley, rye, triticale and oats was analyzed. It was shown that large-scale QTL detections provide new opportunities for increasing the resistance; however, multi-step phenotypic selection still remains to be the most effective tool. Pedigree analyses indicated that the latest progress reached in this field was obtained through the cumulation of resistance genes coming from heterogeneous sources with different response to FHB.

“…Such a high level of polymorphism has never been reported before. Polymorphic rate of SSR were usually low, about 10-30 % Zhou et al 2002;Yang et al 2005b), and 40 % was the highest in a rare case (Bourdoncle and Ohm 2003). In this study, we evaluated over 2,000 SSR primers and carefully selected the set of 384 primers (Supplemental Fig.…”
