“…Most forms of resistance to TuMV in B. rapa and B. napus were found to be dominant and effective against specific TuMV isolates/ genotypes. Recently, several accessions of B. rapa have been demonstrated to exhibit broad-spectrum resistance to TuMV (Liu et al 1996). The genes retr01 (recessive) and ConTR01 (dominant), which control broad spectrum resistance to TuMV in the Chinese cabbage line RLR22 with an epistatic effect, have been identified (Rusholme 2000) and mapped to the upper portion of chromosome R4 and R8, respectively (Rusholme et al 2007).…”

X. 2011. Inheritance and development of EST-SSR marker associated with turnip mosaic virus resistance in Chinese cabbage. Can. J. Plant Sci. 91: 707Á715. Turnip mosaic virus (TuMV) is one of the major pathogens infecting Brassica crops (including Chinese cabbage), and often causes serious reductions in yield and quality. Breeding for resistant cultivars is complicated by the existence of numerous TuMV strains and isolates. The objective of this research was to determine the mode of inheritance and to develop molecular markers associated with TuMV resistance in Chinese cabbage. F 1 and F 2 populations were developed from the cross between 71-36-2 (susceptible) and 73 (resistant) lines and mechanically inoculated with TuMV-C4. Inheritance analysis by visual scoring and enzymelinked immunosorbent assay (ELISA) indicated that resistance to TuMV-C4 in this cross was controlled by one recessive gene. A total of 132 EST-SSR primers were designed from EST sequences available in public databases. Seven primers detected polymorphism between parental genotypes. Marker HCC259 was associated with the TuMV resistance Ph-retr02. The distance between the marker and the TuMV resistance gene retr02 was 3.8 cM. This is the first co-dominant marker linked to the TuMV resistance gene with a distance less than 5.0 cM in Chinese cabbage. This marker was suitable for TuMV-C4 resistance screening in progenies from the cross between lines 73 (resistant) and susceptible line, 71-36-2. The usefulness of this marker was validated in 21 additional resistant and susceptible lines. This marker has the potential to simplify and accelerate breeding Chinese cabbage cultivars resistant to TuMV-C4. . et Song, X. 2011. He´ritabilite´et de´veloppement d'un marqueur EST-SSR associe´a`la re´sistance du chou chinois au virus de la mosaı¨que du navet. Can. J. Plant Sci. 91: 707Á715. Le virus de la mosaı¨que du navet (TuMV) est l'un des principaux agents pathoge`nes qui affectent les cultures du genre Brassica (notamment le chou chinois). Il entraıˆne souvent de graves diminutions du rendement et de la qualite´. L'existence de nombreux isolats et souches du virus complique la cre´ation de varie´te´s re´sistantes. La recherche devait pre´ciser l'he´ritabilite´de la re´sistance au TuMV chez le chou chinois et permettre le de´veloppement de marqueurs mole´culaires associe´s a`cette re´sistance. Les auteurs ont obtenu des populations F 1 et F 2 apre`s croisement des ligne´es 71-36-2 (sensible) et 73 (re´sistante), puis ont me´caniquement inoculeĺ e TuMV-C4 aux plants. L'analyse de l'he´re´dite´par e´valuation visuelle et par dosage immunoenzymatique (ELISA) indique que la re´sistance des hybrides a`TuMV-C4 est re´gie par un ge`ne re´cessif.

“…Liu et al . () also used symptom types and disease severity indices on a variety of brassica species to define seven strains (Tu1–7). Other schemes are based on differential lines of a single species, either B. rapa (strains C1–C4; Provvidenti, ; strains C1–C5; Green & Deng, ) or B. napus (pathotypes 1–12) (Walsh, ; Jenner & Walsh, ).…”

Turnip mosaic virus (TuMV), the only potyvirus known to infect brassicas, is a devastating virus threatening many economically important brassica crops, including cabbage, Chinese cabbage, oilseed rape and mustard. TuMV disease, which was first discovered in the United States, is now found worldwide, especially in Europe, Asia and North America. TuMV results in a yield loss of up to 70% and has a wide host range, infecting most cruciferous plants, as well as many non-cruciferous species. This virus is also characterized by high pathotype diversity because of its highly variable genome structure and has been divided into 12 pathotypes. These characteristics, as well as its nonpersistent transmission mode by as many as 89 aphid species, mean the disease is difficult to prevent through traditional methods such as the application of chemicals, prompting researchers to seek host resistance for effective control. During the last decade, extensive studies have been conducted to investigate inheritance, mapping and cloning of the TuMV resistance genes, and several NB-LRR-or eIF-encoding loci with divergent molecular mechanisms have been uncovered. These studies have greatly facilitated resistance breeding for brassica crops and have advanced our understanding of virusÀhost interactions.

“…Several workers have found resistance in Chinese cabbage and these have been examined by Hughes et al (2002) and Walsh et al (2002). The most promising resistances appear to be those obtained by Liu et al (1996). From a survey of more than 3,000 accessions tested against 19 major TuMV isolates, eight lines were found that were immune or highly resistant to all TuMV isolates.…”
