We developed bulked segregant analysis as a method for rapidly identifying markers linked to any specific gene or genomic region. Two bulked DNA samples are generated from a segregating population from a single cross. Each pool, or bulk, contains individuals that are identical for a particular trait or genomic region but arbitrary at all unlinked regions. The two bulks are therefore genetically...

in sturgeon aquaculture, where the main purpose is caviar production, a reliable method is needed to separate fish according to gender. currently, due to the lack of external sexual dimorphism, the fish are sexed by an invasive surgical examination of the gonads. development of a non-invasive procedure for sexing fish based on genetic markers is of special interest. in the present study we empl...

Canola quality Brassica juncea has been under development at the Saskatoon Research Centre for several years. Breeding efforts have focused on the development of germplasm with improved seed quality characteristics including superior fatty acid profiles, low glucosinolates and high oil content. Future breeding efforts in this crop would be greatly facilitated through the development of molecula...

In this study we investigated the genetic control of avirulence in the diploid oomycete pathogen Phytophthora infestans, the causal agent of late blight on potato. The dominant avirulence (Avr) genes matched six race-specific resistance genes introgressed in potato from a wild Solanum species. AFLP markers linked to Avr genes were selected by bulked segregant analysis and used to construct two ...

pod length is one of the effective components on canola yield selection on the basis of which can increase not only the seed yield but also the oil yield. molecular markers asso-ciated with long pod loci were identified in a doubled haploid population derived from a cross between the canola lines ‘quantum’ (long pod) ‘china a’ (short pod) using rapd and bulked segregant analysis. a molecular ma...

a study was conducted to identify ssr markers linked to leaf rust resistance genes lr24 and lr28 and to be used for marker-assisted selection (mas) to transfer both genes to a widely cultivated wheat variety mp 3299 under rainfed condition. f2 individuals of the cross mp 3299×nil pbw 343 were used for generating genotypic data employing closely linked scar markers s73719 and s421570 to lr24 and...

Bulked segregant analysis was used to determine randomly amplified polymorphic DNA (RAPD) markers in a specific interval in the middle of chromosome 6 of rice for tagging the photoperiod sensitivity gene. Two pools of F2 individuals (japonica cv. Nipponbare and indica cv. Kasalath) were constructed according to the genotypes of three restriction fragment length polymorphism (RFLP) markers locat...
