ABSTRACT:
The objective of this experiment was to evaluate the water deficit effects on maize yield and yield components. The maize hybrid Pioneer 30F33 was submitted to five irrigation water management treatments. Irrigation management was based on crop maximum evapotranspiration (ETm). Irrigations were applied when cumulative ETm reached values of 14, 22, 30, 38 and 46 mm. The experiment was conducted on a set of 20 drainage lysimeters under a mobile rain shelter. Leaf area index and plant height were measured twice a weak in each
treatment from 29 days after emergency to harvest. Soil moisture were measure in each soil !ayer (0-20; 20-40; 40-53; 53-66 and 66-100 cm), twice a weak. Results of leaf area and plant height were similar during crop growing season for ali irrigation strátegies, and aboveground biomass accumulation at harvest was also similar for ali treatments. Maximum technical maize yield was obtained applying irrigation when cumulative ETm reached value of the 34 mm. Total irrigation depth applied was 264, 281, 278, 279, and 282 mm using the irrigation
management of 14, 22, 30, 38 e 46 mm of cumulative ETm. The use of irrigation application based on cumulative ETm values in Southern Brazil results in a easier practice to increase water use efficiency, increase maize yield and reduce application cost. |

Abstract:
Aegilops tauschii, the diploid wild progenitor of the D subgenome of bread wheat, is a reservoir of genetic diversity for improving bread wheat performance and environmental resilience. Here we sequenced 242 Ae. tauschii accessions and compared them to the wheat D subgenome to characterize genomic diversity. We found that a rare lineage of Ae. tauschii geographically restricted to present-day Georgia contributed to the wheat D subgenome in the independent hybridizations that gave rise to modern bread wheat. Through k-mer-based association mapping, we identified discrete genomic regions with candidate genes for disease and pest resistance and demonstrated their functional transfer into wheat by transgenesis and wide crossing, including the generation of a library of hexaploids incorporating diverse Ae. tauschii genomes. Exploiting the genomic diversity of the Ae. tauschii ancestral diploid genome permits rapid trait discovery and functional genetic validation in a hexaploid background amenable to breeding.
