Detection of bacterial blight resistance genes in basmati rice landraces.
Aromatic basmati rice is vulnerable to bacterial blight disease. Genes conferring resistance to bacterial blight have been identified in coarse rice; however, their incorporation into basmati varieties compromises the prized basmati aroma. We identified bacterial blight resistance genes Xa4, xa5, Xa7, and xa13 in 52 basmati landraces and five basmati cultivars using PCR markers. The Xa7 g...
متن کاملApplication of STS markers for leaf rust resistance genes in near-isogenic lines of spring wheat cv. Thatcher.
Sequence tagged site (STS) markers for eight resistance genes against Puccinia recondita f. sp. tritici were used to screen a set of near-isogenic lines of wheat cv. Thatcher containing in total 40 different Lr genes and their alleles. Polymerase chain reaction (PCR) analysis was carried out by using STS, SCAR and CAPS primers specific for the leaf rust resistance genes Lr1, Lr9, Lr10, Lr19, Lr...
متن کاملMetabolite and mineral analyses of cotton near-isogenic lines introgressed with QTLs for productivity and drought-related traits.
Quantitative trait loci (QTLs) for yield and drought-related traits were exchanged via marker-assisted selection between elite cultivars of two cotton species, Gossypium barbadense (GB) cv. F-177 and Gossypium hirsutum (GH) cv. Siv'on. Three of the resultant near-isogenic lines (NILs), each introgressed with a different QTL region, expressed an advantage in osmotic adjustment (OA) and other dro...
متن کاملUnraveling epistasis with triple testcross progenies of near-isogenic lines.
Libraries of near-isogenic lines (NILs) are a powerful plant genetic resource to map quantitative trait loci (QTL). Nevertheless, QTL mapping with NILs is mostly restricted to genetic main effects. Here we propose a two-step procedure to map additive-by-additive digenic epistasis with NILs. In the first step, a generation means analysis of parents, their F(1) hybrid, and one-segment NILs and th...
متن کاملDevelopment and evaluation of near-isogenic lines for brown planthopper resistance in rice cv. 9311
Brown planthopper (BPH) is the most destructive pest of rice in Asia. To date 29 BPH resistance genes have been identified, but only a few genes are being used in breeding due to inefficient markers for marker-assisted selection (MAS) and little knowledge of the real effects of the genes. In this study we individually transferred 13 genes or QTLs (Bph14, QBph3, QBph4, Bph17, Bph15, Bph20, Bph24...
