Although seed treatment is an effective alternative at the moment, the cost of seed treatment is high. Breeding for downy mildew resistance is the most cost effective. The present study is aimed at mapping the genes controlling downy mildew resistance in maize. The Ki14 x Hi31 population ...
of large-scale QTL cloning method hampers systematic dissection of genetic base of quantitative traits. Here, the authors develop a multi-omics data-based technique for large-scale and rapid cloning of quantitative genes of tassel branch number and discovery of selection signatures in maize breeding....
ENGLISH ABSTRACT: Gray leaf spot (GLS) of maize, caused by the fungus Cercospora zeae-maydis, can reduce grain yields by up to 60% and it is now recognized as one of the most significant yield-limiting diseases of maize in many parts of the world. The most sustainable and long-term ...
To summarize, this book describes technologies for identification of genes of interest through genetic mapping, recaps the major applications of MAS to plant breeding; lists examples in which MAS is being applied to various breeding programs, and emphasizes the various difficulties that limit the ...
Another approach is followed to identify genes that are differentially transcribed under varying developmental conditions. The direct identification of genes of the maize chloroplast chromosome by in vitro linked transcription–translation of DNA sequences is feasible because of the relatively small size of...
Thus, in addition to the identification and characterization of enhancers in Arabidopsis and other species (e.g., rice, wheat, and maize) that became popular through 1D genomic approaches28,29,30,31,32,33, there is an urgent need for a fine-scale comprehensive analysis method that can ...

Leaf rust (LR), stripe rust (YR) and tan spot (TS) are some of the important foliar diseases in wheat (Triticum aestivumL.). To identify candidate resistance genes for these diseases in CIMMYT's (International Maize and Wheat Improvement Center) International bread wheat screening nurseries, ...
These traits are all quantitative and controlled by multiple genes. There have been many reports on quantitative trait loci (QTL) analyses of seed vigor traits over recent years in Arabidopsis, rice, wheat, rape, maize, and barley, etc19,20,21,22,23. Progress has also been made in the ...
“QTL hotspot” region for drought tolerance7. It is believed that a component trait-based selection of plants is more useful inbreeding for improved drought tolerance. Different types of molecular markers have been used to identify the QTL/genes for these traits. A total of 93 QTLs for ...
