Abstract Peanut, with high oil content, has been a major oil and food crop globally. The compositions of the fatty acids are the common factors in determining the oil quality. In the present study, an F2 segregated population with 140 individuals derived from the cross of Weihua8 (a cultivar) and 12L49 (a line with high oleic acid concentration) was used to construct a genetic map and conduct QTL mapping analysis. A total of 103 polymorphic SSR primers were utilized for genotyping the RILs and finally generating the SSR loci. Within the 103 SSR loci, a genetic linkage map, covering a total… More >

Abstract Identification of quantitative trait loci (QTLs) controlling yield and yield-related traits in rice was performed in the F₂ mapping population derived from parental rice genotypes DHMAS and K343. A total of 30 QTLs governing nine different traits were identified using the composite interval mapping (CIM) method. Four QTLs were mapped for number of tillers per plant on chromosomes 1 (2 QTLs), 2 and 3; three QTLs for panicle number per plant on chromosomes 1 (2 QTLs) and 3; four QTLs for plant height on chromosomes 2, 4, 5 and 6; one QTL for spikelet density on chromosome 5; four QTLs… More >

Abstract Gene and quantitative trait loci (QTLs) localization in a model species allow to know their organization in the genome, and the possibility for the isolation and cloning of genes with agronomic importance. Seventy-three recombinant inbred lines (RILs) derived from the cross of Arabidopsis thaliana (L.) Heynh. ecotypes Columbia (Col) x Landsberg erecta (Ler) were grown in a greenhouse under contrasting soil moisture conditions (irrigated and water deficits). During their growth, some phenological (days to flowering) and plant growth traits (plant height, and number of nodes and leaves per plant) were measured. Significant differences for plant height and nodes per plant… More >
