We are upgrading the repository! We will continue our upgrade in February 2025 - we have taken a break from the upgrade to open some collections for end-of-semester submission. The MS-GIST Master's Reports, SBE Senior Capstones, IPLP dissertations, and UA Faculty Publications collections are currently open for submission. Please reach out to repository@u.library.arizona.edu with your questions, or if you are a UA affiliate who needs to make content available in another collection.

| dc.description.abstract | Three maize populations developed for their ability to withstand drought and salinity, and their reciprocal F1 crosses were tested under induced water stress and normal moisture conditions. Two commercial hybrids and one open-pollinated variety were also included in the study. The objective was to investigate yield and its components under induced drought. Significant differences in yield were observed in both irrigation treatments. DeKalb 689, one of the commercial hybrids, outyielded all the other entries under wet conditions, whereas under dry conditions the open-pollinated variety, Page Ranch, had the highest yield. Significant differences between populations and their hybrids were also observed. Significant correlations were noted in grain yield as observed in wet and dry conditions and the reduction in the number of ears per plant was positively correlated with the reduction in grain yield resulting from drought. | |
