“…From the distribution of the segregation markers, it could be seen that 35 distorted markers were mainly distributed in 11 linkage groups, and most of the distorted markers showed different degrees of aggregation phenomenon in the linkage groups. This phenomenon was also found in other crops, such as longan, and peach [22,27].…”

“…Due to chromosome rearrangement, deletion, and other factors in genetic replication, a large number of markers often appeared to be segregation in the process of constructing the genetic map [27,30]. In this study, 71 markers were observed as segregation products, and 35 segregated markers were positioned to the map, accounting for 12.5% of the total number of markers in the map.…”

“…The construction of genetic maps in fruit started 1994 [4]. With the rapid development of molecular biology techniques, great progress has been made in recent years, resulting in genetic maps being constructed for numerous fruit trees, including peach [20,21], pear [22,23], citrus [24], and others [25][26][27]. These days, genetic maps for F1 hybrids of apple are being constructed using various cultivated varieties for both parents, as the closer genetic relationship could highlight more discrete differences.…”

Construction of a Genetic Linkage Map and QTL Analysis of Fruit-related Traits in an F1 Red Fuji x Hongrou Apple Hybrid

A genetic linkage map of the apple, composed of 175 SSR and 105 SRAP markers, has been constructed using 110 F1 individuals obtained from a cross between the ‘Red Fuji’ Malus domestica and ‘Hongrou’ Malus sieversii cultivars, which have relatively high levels of DNA marker polymorphism and differ remarkably in fruit-related traits. The linkage map comprised 17 linkage groups, covering 1299.67 cM with an average marker distance of 4.6 cM between adjacent markers, or approximately 91% of Malus genome. Linkage groups were well populated and, although marker density ranged from 2.1 to 9.5 cM, just 10 gaps of more than 15 cM were observed. Moreover, just 12.5% of markers displayed segregation distortion. The present genetic linkage map was used to identify quantitative trait loci (QTLs) affecting fruit-related traits. 23 QTLs for ten fruit traits were detected by multiple interval mapping: 3 QTLs for Vc content, One QTL for single fruit weight, 2 QTLs for peel-phenols content, 2 QTLs for flesh-hardness, 2 QTLs for diameter, 6 QTLs for acid content, 1 QTL for sugar content, 2 QTLs for soluble solids content, 2 QTLs for flesh-phenols and 2 QTLs for brittleness. These QTLs were located on linkage groups C1, C2, C3, C5, C6, C7, C9, C10, C14 and C17, respectively. The phenotypic variations exhibited by each QTL ranged from 2% to 72%, and their LOD values varied from 2.03 to 8.93, of which five QTLs were major effect genes (R2 ≥ 10%). The tight linkage markers (*me2em7-460f, *MS01a03-180m, *me1em6-307m, *CH05c06-102f, *me1em8-423f) would be helpful to elucidate the molecular mechanisms of apple domestication and breeding in the future.

“…Using the SSR-enrichment method of Techen et al ( 2010 ) in combination with pyrosequencing, 384 markers were developed and are being veri fi ed for this species. Guo et al ( 2010 ) constructed a linkage map using 94 progeny from a cross of 'Fengliduo' and 'Dawuyuan'. 'Fengliduo' is a high-quality cultivar, while 'Dawuyuan' has a large fruit size.…”

The genetic improvement of tropical fruit trees is limited when compared to progress achieved in temperate fruit trees and annual crops. Tropical fruit tree breeding programs require signi fi cant resources to develop new cultivars that are adapted to modern shipping and storage requirements. The use of molecular markers in tropical fruit tree breeding is greatly assisting in solving a number of dif fi cult challenges for breeders such as the development of complex family structures for recombination mapping and for recurrent selection. A review of the literature on molecular markers development and new techniques for increasing single-nucleotide polymorphic markers is discussed. The development of marker-assisted breeding for these tropical tree crops is also discussed.

“…In recent years, molecular genetic maps have been successfully constructed for most fruit trees, such as apple, [2À4] pear, [5] tangerine, [6] cherry, [7] banana, [8] olive, [9] papaya, [10] peach, [11] lychee [12] and longan. [13] Hawthorn (Crataegus pinnatifida Bge.) belongs to Rosaceae (Rosaceae) and is native to China.…”

The F1 hybrid population was a result from the crossing of 'Damianqiu' and 'Qiujinxing'. 'Damianqiu' was the female parent and 'Qiujinxing' was the male parent. Ninety-two F1 individual plants and their parents, in total of 94 materials, were chosen for the sequence-related amplified polymorphism analysis. The Joinmap3.0 software was used to construct the molecular genetic map of 'Damianqiu' and 'Qiujinxing', respectively. According to the result, the molecular linkage map of 'Damianqiu' has 21 linkage groups with 96 markers, which covers a genetic distance of 686.67 cM, with an average interval of 7.15 cM. 'Qiujinxing' has 18 linkage groups with 89 markers, which covers a genetic distance of 529.58 cM, with an average interval of 5.95 cM. The aim of this study was to create the first hawthorn molecular genetic map, which could be used as a foundation for gene mapping and assisted selection in the future.
