Reduction in Salmonella enteritidis (SE) contamination is of importance for poultry production as well as for food safety. The objectives of this study were to identify potential genetic markers of antibody response to SE vaccine in young broiler chicks and then to confirm this linkage in broiler-cross offspring, as well as to explore interactions of marker alleles with dam line and sex. The in...

Chinese cabbage (Brassica rapa L.) is one of the most important and highly nutritious vegetables in China belonging to Brassicaceae family. Flowering or bolting critical developmental stages flowering plants. For spring-sown cabbage, late-bolting desirable over early-bolting according consumer preferences. We determined inheritance pattern trait using F1 F2 generated from a cross between ‘SY200...

Mutagenesis is a useful tool in many crop species to induce heritable genetic variability for trait improvement and gene discovery. In this study, forward screening of a soybean fast neutron (FN) mutant population identified an individual that produced seed with nearly twice the amount of sucrose (8.1% on dry matter basis) and less than half the amount of oil (8.5% on dry matter basis) as compa...

An F2 population derived from a cross between apetalous line' APT02 'and normal petalled cultivar 'ZS NO.4' was used for molecular marker searching and chromosomal mapping of the gene(s) controlling petal-loss trait in Brassica napus. Twenty pairs of AFLP primers and 170 pairs of SRAP primers were selected and screened from two parents. In further selection through bulked segregant analysis (BS...

Oilseed rape (Brassica napus L.) is one of the most important oil crops in China as well as worldwide. Branch angle as a plant architecture component trait plays an important role for high density planting and yield performance. In this study, bulked segregant analysis (BSA) combined with next generation sequencing technology was used to fine map QTL for branch angle. A major QTL, designated as...

Yellow rust (stripe rust), caused by Puccinia striiformis f. sp. tritici, is one of the most destructive foliar diseases of wheat in Egypt and worldwide. In order to identify wheat genotypes resistant to yellow rust and develop molecular markers associated with the resistance, fifty F8 recombinant inbred lines (RILs) derived from a cross between resistant and susceptible bread wheat landraces w...

The cucumber (Cucumis sativus L.) exhibits extensive variations in fruit size and shape. Fruit length is an important agronomic and domesticated trait controlled by quantitative trait loci (QTLs). Nonetheless, the underlying molecular and genetic mechanisms that determine cucumber fruit length remain unclear. QTL-seq is an efficient strategy for QTL identification that takes advantage of bulked...
