“…However, there was no positional trend in the segregation distortion within each linkage group. This result differed from that in a previous study, in which many Euphytica (2009) 170:327-338 329 of the distorted loci were clustered at the bottom of LG2 (Cai et al 2004). …”

“…A total of 8.7% (40 of 458 loci) of the SSR markers showed significant segregation distortion in this population (P \ 0.01), a result similar to that previously reported for a zoysiagrass S 2 generation (6%) (Cai et al 2004). Similar numbers of distorted loci were detected in each parent, 'Tawarayama Kita 1' (20 of 335 loci) and 'Muroran 2' (22 of 314 loci), with only two identical markers showing significantly distorted segregation.…”

“…The total map length in the present study is longer than all zoysiagrass genetic maps reported previously: the 1,187 cM genetic linkage map based on 540 SSR and AFLP markers (Cai et al 2005), two AFLP-based linkage maps (932.5 and 1,320 cM; Cai et al 2004 andEbina et al 1999, respectively), and an RFLP-based genetic map of 1,506 cM (Yaneshita et al 1999). …”

“…Two molecular linkage maps were initially constructed from interspecific hybrids of Z. japonica and Z. matrella (Ebina et al 1999;Yaneshita et al 1999) on the basis of amplified-fragment length polymorphism (AFLP) and restriction-fragment length polymorphism (RFLP) markers. Cai et al (2004) also reported an AFLP-based high-density linkage map for Z. japonica.…”

A consensus genetic linkage map with 447 SSR markers was constructed for zoysiagrass (Zoysia japonica Steud.), using 86 F 1 individuals from the cross 'Muroran 2' 9 'Tawarayama Kita 1'. The consensus map identified 22 linkage groups and had a total length of 2,009.9 cM, with an average map density of 4.8 cM. When compared with a previous AFLP-SSR linkage map, the SSR markers from each linkage group mapped to similar positions in both maps. Eight pairs of linkage groups from the AFLP-SSR map were joined into eight new groups in the current map. This zoysiagrass consensus map contained 35 SSR markers exhibiting high homology with rice genomic sequences from known chromosomal locations. This allowed synteny to be identified between Zoysiagrass linkage groups 2, 3, 9, 19 and rice chromosomes 3, 12, 2, 7 respectively. These results provide important comparative genomics information and the new map is now available for quantitative trait locus analysis, marker-assisted selection and breeding for important traits in zoysiagrass.

“…More recently, high-density genetic linkage maps have been constructed for zoysiagrass using AFLP and SSR markers (Cai et al 2004, Li et al 2009). In zoysiagrass, morphological characteristics that can be visually assessed are important factors when determining turf quality, while QTLs for tolerance of environmental stressors such as salinity and freezing may be widely distributed among species.…”

Tropical grasses have been widely utilized as warm-season grasses in the warm temperate zone since the early 20th century because of their high yields as well as for perennial forages in their native tropical areas. The high yield of tropical grasses is mainly due to C4 photosynthesis. However, the soaring demands for animal production sparked by economic development in tropical countries mean genetic improvement of such grasses is urgently needed. Considerable breeding efforts have been made to create and develop new tropical grass cultivars, although direct selection from natural populations remains the main method used for breeding. Cross-breeding has not proliferated due to a lack of genetic information concerning the polyploidy, high sterility, outcrossing, and apomixis of these grasses, although several of these difficulties are starting to be resolved by advanced research using molecular biology tools. These tools are an effective means of achieving genetically improving of tropical grasses, and further development is anticipated. In this review, achievements in the improved guineagrass, brachiariagrass, sorghum, and zoysiagrass are introduced and discussed.

Zoysiagrasses (Zoysia spp.) are relatively low‐input and warm‐season turfgrasses which have grown in popularity in the United States since their introduction in the 1890s. Over 30 improved zoysiagrass cultivars were released in the past three decades, but many lack freezing tolerance and their use is limited to warm‐humid climates. Understanding the genetic controls of winter hardiness and freezing tolerance in zoysiagrass could considerably benefit the breeding efforts to increase tolerance to freezing stress. In the present study, controlled environment acclimation and freezing tests were used to evaluate a Meyer × Victoria zoysiagrass mapping population for post‐freezing surviving green tissue (SGT) and regrowth (RG). Quantitative trait loci (QTL) mapping analysis identified nine QTL associated with SGT, eight QTL linked to RG, and 22 QTL common in both traits, accounting for between 6.4 and 12.2% of the phenotypic variation. Eleven regions of interest overlapped with putative winter injury QTL identified in a previous field study. Upon sequence analysis, homologs of several abiotic response genes were found underlying these overlapping QTL regions. The homologs of these gene encode transcription factors, cell wall modification‐related proteins, and defense signal transduction‐related proteins. After further validation, these QTL and their associated markers have potential to be used in future breeding efforts for the development of a broader pool of zoysiagrass cultivars capable of surviving in cold climates.
