Genomic Prediction Of Salinity Stress Tolerance In Maize (Zea Mays L.), Vishal Singh
Genomic Prediction Of Salinity Stress Tolerance In Maize (Zea Mays L.), Vishal Singh
Student Research Symposium
Maize is the largest crop in the world in terms of production. Utah, maize is a potential fodder crop. With increasing climate change, soil salinity is also increasing worldwide. Soil salinity is very detrimental to plants' growth and development and crop production. For a fodder crop, plant biomass is an important trait, and maize biomass is adversely affected by salinity stress, especially at the seedling stage. A Selection of salt-tolerant breeding material is a time-consuming process and its complexity is further increased by significant heterogeneity in soil salinity under field based evaluation. Genomic prediction is an emerging tool that can …

Stomatal behavior in response to drought has been the focus of intensive research, but less attention has been paid to stomatal density. In this study, 5-week-old maize seedlings were exposed to different soil water contents. Stomatal density and size as well as leaf gas exchange were investigated after 2-, 4- and 6-weeks of treatment, which corresponded to the jointing, trumpeting, and filling stages of maize development. Results showed that new stomata were generated continually during leaf growth. Reduced soil water content significantly stimulated stomatal generation, resulting in a significant increase in stomatal density but a decrease in stomatal size and …
