An integrated molecular linkage map of pepper (Capsicum annuum L.), including mainly RFLP and RAPD markers, has been constructed by alignment of three intraspecific linkage maps generated by segregating doubled-haploid progenies. A total of 85 markers covered approximately 820 cM in 14 linkage groups. Four linkage groups were assigned to 4 chromosomes. Two(More)
A molecular map of pepper (Capsicum sp.) totalling 720 cM has been constructed in an interspecific F2 cross with restriction fragment length polymorphisms and isozymes. Nineteen linkage groups were formed from 192 molecular markers. Twenty-six markers showed no linkage to any others. Twenty-eight markers showed significant deviation from expected Mendelian(More)
Genetic analysis of resistance to PVY in androgenetic doubled haploid lines, F1, F2 and backcross progenies of the Mexican pepper line, CM 334 (Capsicum annuum L.), was performed. Three reaction types were observed when seedlings were inoculated with several PVY strains of different pathotypes and with an American PeMV strain. Resistant genotypes never(More)
In order to increase the resistance level of pepper (Capsicum annuum) to Phytophthora capsici the main sources of genetic resistance were intercrossed. The parents included 7 varieties from different origins of partial resistance to P. capsici and to other soilborne pathogens. Two cycles of recurrent selection were performed by 7 plant breeders who screened(More)
‘Criollo de Morelos 334’ (CM334) is one of the most promising sources of resistance to Phytophthora capsici in pepper. This Mexican accession is distantly related to bell pepper and its resistance displays a complex inheritance. The QTLs involved in resistance to P. capsici were previously mapped. In order to transfer the resistance factors from CM334 into(More)
Two cycles of recurrent selection were performed in a population including 7 small fruited varieties of pepper (Capsicum annuum) with low resistance level to Verticillium and resistance to other soilborne pathogens. The collaboration of 7 plant breeders in this work and the use of 2 artificial methods of inoculation allowed screening of numerous plants for(More)
Lipid excipients are usually used for the development of sustained-release formulations. When used in relatively high quantities, Precirol ATO 5 imparts sustained-release properties to solid oral dosage forms, by forming a lipid matrix. To control or adjust the drug release kinetics from such lipid matrix however, one must often resort to complementary(More)
Doubled haploid peppers resistant in France to specific strains of tobacco etch virus (TEV) and pepper mottle virus (PeMV) were indexed for resistance to USA strains of TEV and PeMV. The doubled haploids were inoculated when four to six true leaves had developed. The peppers were indexed after an incubation period, and a disease index was calculated. Plants(More)
