“…The inheritance of one or more recessive genes and of one or more polygenes has been reported in the resistance to fusarium wilt (Fusarium oxysporum f. sp. melonis) in melon (Cucumis melo L.; Nakazumi and Hirai, 2004), which is similar to the results obtained in the present study. There were some reports that resistance to scab in apple and pear is controlled by both a dominant major gene and polygenes (Abe et al, 2000;Lamb et al, 1985).…”

Loquat canker, caused by Pseudomonas syringae pv. eriobotryae, is a serious disease of loquat [Eriobotrya japonica (Thunb.) Lindl.] in some countries such as Japan. Therefore, improved canker resistance is an important objective for loquat breeding. The resistance to loquat canker Group C in descendants of ‘Shiromogi’ was expressed only in homozygotes with a recessive gene at a single locus, which was designated pse-c/pse-c. ‘Champagne’, which is distantly related to ‘Shiromogi’, is another cultivar with resistance to Group C. The inheritance of this resistance in progenies of crosses between ‘Champagne’ and susceptible cultivars was examined. The offspring seedlings from 14 crosses between ‘Champagne’ (pse-c/pse-c) and 12 susceptible cultivars (Pse-c/Pse-c or Pse-c/pse-c) were classified into two types of resistant and susceptible. All of the hybrid progenies between ‘Champagne’ (pse-c/pse-c) and Pse-c/Pse-c parents showed two types of resistant and susceptible. The proportion of resistant offspring showed great differences significantly, depending on the hybrid combinations. It ranged from 0.203 to 0.596 with an average of 0.407. It indicated that the resistance was controlled by one or more additional genes or loci other than the Pse-c (pse-c) locus. In addition, the proportion of resistant offspring from crosses between ‘Champagne’ (pse-c/pse-c) and Pse-c/pse-c parents ranged from 0.463 to 0.701 (and averaged 0.601), which seriously deviated from the segregation of 1:1, indicating that the segregation was both Mendelian and polygenic in a threshold character. The proportion of resistant seedlings cannot be predicted by the phenotype and the genotype in the Pse-c (pse-c) locus. Therefore, the general combining ability of ‘Champagne’ resulting from the additional gene effect was estimated, which was 0.407 and 0.101 for ‘Champagne’ × Pse-c/Pse-c and ‘Champagne’ × Pse-c/pse-c cultivars, respectively. The gene effect of susceptible cultivars ranged from –0.204 (‘Yougyoku’) to +0.189 (‘Togoshi’) for ‘Champagne’ × Pse-c/Pse-c cultivars and from –0.138 (‘Taisho’) to +0.089 (‘Nagasakiwase’) for ‘Champagne’ × Pse-c/pse-c cultivars.

“…Charentais T has no resistance gene and is susceptible to all four races. A gene that confers resistance to race 1,2 has not been identiWed, although partial and polygenic resistance was reported (Nakazumi and Hirai 2004;Perchepied et al 2005). Recently, melon line BIZ was reported to have two complementary recessive genes that confers nearly complete resistance to race 1,2 (Herman and Perl-Treves 2007).…”

Resistance to Fusarium oxysporum f.sp. melonis race 2 is conferred by a single dominant gene, Fom-1 in melon. Here, we identiWed DNA markers tightly linked to Fom-1 that could be used for marker assisted selection in breeding programs. First, we developed 125 F 2 plants derived from the cross between melon lines P11 (fom-1fom-1) and MR-1 (Fom-1Fom-1). Using the F 2 population, we constructed a linkage map including 14 SSR markers which had not been mapped previously. Fom-1 was conWrmed to be allocated to linkage group 7. Then, we identiWed four AFLP markers using bulked segregant analysis. The AFLP marker TAG/GCC-470 was completely linked to Fom-1 and other three markers were mapped near Fom-1. TAG/GCC-470 and TCG/GGT-400 were respectively converted to STS and CAPS markers. Usefulness of DNA markers was conWrmed in the analysis with several melon cultivars and lines.

“…At least three additional minor quantitative trait loci have also been characterized (Branham et al 2018). Resistance to race 1.2 is quantitative (Nakazumi and Hirai 2004;Perchepied et al 2005).…”
