چکیده

A partial linkage map was constructed for the sweet cherry (Prunus avium L.) cultivar Emperor Francis from a population of 56 microspore-derived callus culture individuals. The callus cultures were genotyped for two allozymes and 90 random amplified polymorphic DNA (RAPD) markers using 79 random decanucleotide DNA primers and the polymerase chain reaction (PCR). Eighty-nine markers mapped to 10 linkage groups totaling 503.3 cM. DNA blot and hybridization analysis using five cloned RAPDs as probes demonstrated that one of the decanucleotide primers amplified a region of the Emperor Francis genome containing a unique sequence, whereas the other four decanucleotide primers amplified regions of the Emperor Francis genome containing repeated sequences. The five cloned RAPD probes also recognized putative homologous regions in ground cherry, P.fruticosa Pall., and sour cherry, P. cerasus L., a naturally occurring allopolyploid between P.fruticosa and P.avium.

QTL analysis for diamondback moth resistance in canola (Brassica napus L.)

Diamondback moth (DBM), Plutella xylostella L. is the most injurious defoliage insect pest of canola in Ardabil province of Iran. It occurs annually and causes damage in canola fields. This study was performed to identify QTLs controlling resistance to diamondback moth using SSR and RAPD markers. An F2:4 population of 180 families derived from crossing between cv. ‘SLMO46’ and cv. ‘Quantum’ wer...

Construction of Commercial Sweet Cherry Linkage Maps and QTL Analysis for Trunk Diameter

A cross between the sweet cherry (Prunus avium) cultivars 'Wanhongzhu' and 'Lapins' was performed to create a mapping population suitable for the construction of a linkage map. The specific-locus amplified fragment (SLAF) sequencing technique used as a single nucleotide polymorphism (SNP) discovery platform and generated 701 informative genotypic assays; these, along with 16 microsatellites (SS...

Genotypes-Independent Optimization of Nitrogen Supply for Isolated Microspore Cultures in Barley

To establish a high-efficiency system of isolated microspore culture for different barley genotypes, we investigated the effects of nitrogen sources and concentrations on callus induction and plant regeneration in different barley genotypes. The results showed that the organic nitrogen sources greatly increased the callus induction, and the great reduction of total nitrogen sources would signif...

Construction of High Density Sweet Cherry (Prunus avium L.) Linkage Maps Using Microsatellite Markers and SNPs Detected by Genotyping-by-Sequencing (GBS)

Linkage maps are valuable tools in genetic and genomic studies. For sweet cherry, linkage maps have been constructed using mainly microsatellite markers (SSRs) and, recently, using single nucleotide polymorphism markers (SNPs) from a cherry 6K SNP array. Genotyping-by-sequencing (GBS), a new methodology based on high-throughput sequencing, holds great promise for identification of high number o...

A QTL linkage map of safflower for yield under drought stress at reproductive stage

 This study reports QTL mapping for seed yield and its components in safflower genome under drought stress. The F3 families derived from the cross Mex.22-191 (tolerant) × IL.111 (sensitive) were evaluated for agronomic traits in safflower. Drought tolerance was evaluated during 10% of the flowering stage. To identify QTLs underlying tolerance to drought, mapping quantitative trait loci (QTLs) w...
