Breeding for MLB resistance and days to flowering can be accelerated by understanding their genetics and identifying genomic regions contributing for their expression. Two F2s population with 338 and 349 individuals along with their recombinants inbred lines (RILs) having 283 and 277 individuals were developed from F1 crosses HKIPC4P × CML269 and ESM113 × P72clXbrasil1117 for genetic studies of MLB resistance and flowering. The populations along with their parents were screened under artificially inoculated conditions at hot-spot sites during 2015–17. Race O inoculum was artificially inoculated in the leaf whorl of each plant at 4-6 leaf stage. The inoculation was repeated after 8-10 days of first inoculation to avoid any chance of disease escape. The partial dominance in F1s, normal distribution patterns in F2s and RILs for both the traits has indicated their polygenic nat...

However, enhanced acreage and adoption of monoculture practices rendered the crop vulnerable to several diseases. Phytophthora root and stem rot (PRSR) caused byPhytophthora sojaeis one of the most prevalent diseases adversely affecting soybean production globally. Deployment of genetic resistance is the most sustainable approach for avoiding yield losses due to this disease. PRSR resistance is complex in nature and difficult to address by conventional breeding alone. Genetic mapping through a cost-effective sequencing platform facilitates identification of candidate genes and associated molecular markers for genetic improvement against PRSR. Furthermore, with the help of novel genomic approaches, identification and functional characterization ofRps(resistance toPhytophthora sojae) have also progressed in the recent past, and more than 30R...

Integrating genomics with modern breeding methods holds enormous potential in dissecting the genetic architecture of this complex trait and accelerating crop improvement. Abstract Insect resistance in crops has been a major research objective in several crop improvement programs. However, the use of conventional breeding methods to develop high-yielding cultivars with sustainable and durable insect pest resistance has been largely unsuccessful. The use of molecular markers for identification and deployment of insect resistance quantitative trait loci (QTLs) can fastrack traditional breeding methods. Till date, several QTLs for insect pest resistance have been identified in field-grown crops, and a few of them have been cloned by positional cloning approaches. Genome editing technologies, such as CRISPR/Cas9, are paving the way to tailor insect pest resistance loci for designing c...

Thus, knowing the pathogens, their ecology, distribution, virulence patterns, and variability is important in minimizing diseases and the gap between actual and attainable yields. Maize is one of a few important crops that civilizations have cultivated for centuries for food and a vast variety of industrial products and it is highly vulnerable to climate change. This review paper provides a complete vision of an agenda for current and future research on maize. Advances in technologies for the high-throughput analysis of gene expression have made it possible to discriminate host, pathogen, and vector responses to different biotic and abiotic stresses and their responses. Initiatives need to be undertaken to synthesize the effects of climate variables on infection rates, though pathosystem specific characteristic...
