The Resistance of Some Tomato Lines against Tomato Spotted Wild Virus, Tomato Yellow Leaf Curl Virus and Root Knot Nematodes (Meloidogyne spp.) by Molecular Markers
نویسندگان
چکیده
In this study, it was attempted to determine the resistance of different tomato lines spotted wilt virus (TSWV), yellow leaf curl (TYLCV), and root-origin nematodes (Meloidogyne spp.) using molecular DNA markers. For purpose, out 96 be tested, Sw5-2 for ripening Ty3P6-25 (TYLCV) marker Mi23, which determines root-knot spp.), were used by PCR. Ty3P6-25, that TYLCV, found susceptible (rr) in 34 lines, heterozygous resistant (Rr) 56 homozygous (RR) 4 lines. addition, no results obtained 2 Marker Sw5-2, TSWV, 57 27 5 No 7 (Mi23) 44 (rr), 11 (Rr), 35 resistant. 6 It concluded markers are useful determining responses TYLCV Meloidogyne spp. can give reproducible reliable a short time.

Phenotypic and Molecular Screening of Tomato Germplasm for Resistance to Tomato Yellow Leaf Curl Virus
Tomato yellow leaf curl virus (TYLCV) is a major tomato virus in tropical and subtropical regions. In this study, 134 accessions of Solanum lycopersicum and six accessions of Solanum peruvianum were assessed for resistance to an Iranian isolate of TYLCV. Plants were inoculated using whiteflies (Bemisia tabaci) and the reaction of plants was evaluated based on either disease symptoms or viral DN...

Tomato (Solanum lycopersicum) production in tropical and subtropical regions of the world is limited by the endemic presence of Tomato yellow leaf curl virus (TYLCV). Breeding programmes aimed at producing TYLCV-resistant tomato cultivars have utilized resistance sources derived from wild tomato species. So far, all reported breeding programmes have introgressed TYLCV resistance from a single w...

The complete genome sequences (2791 and 2793 nt) of isolates of Tomato yellow leaf curl virus-Is (TYLCV-Is) from Spain (SP72/97) and Portugal (Port2/95) were determined. These isolates are closely related to TYLCV-Is isolates reported in Japan (Japan-A and Japan-S) and Israel (Israel/Mild). Comparison of all sequenced isolates of TYLCV-Is showed that part of the genome comprising the intergenic...

ABSTRACT Two tomato yellow leaf curl virus (TYLCV)-resistant plants from accessions LA1777 and LA386 of the wild tomato species Lycopersicon hirsutum have been crossed. The resulting resistant F1 plants were crossed with the domesticated tomato L. esculentum, and a series of selfing was performed. At each generation, individuals were selected for resistance (no symptoms and undetectable viral D...
