Early Maturing

In drought-affected maize production zones with short growing periods, the development and use of early maturing drought-tolerant cultivars can stabilize maize production. We evaluated 10 improved and 25 farmers' early maturing maize varieties under moisture deficit and well-watered conditions for 2 years to identify suitable genetic materials for breeding drought-tolerant cultivars. The varieties exhibited significant differences in grain yield and other traits under both moisture deficit and well-watered conditions. Changes in the rank order of the varieties for grain yield was not significant across the different levels of moisture supply in this study. Grain yield was significantly correlated with days to anthesis, days to silking, plant height, ear height, ear number and anthesis–silking interval (ASI) under the two irrigation treatments and with leaf death scores under moisture deficit, suggesting that the common traits were beneficial in maximizing grain yield under both sufficient water supply and moisture deficit. Grain yield and the traits significantly correlated with it differentiated the early maturing maize varieties into two distinct groups under well-watered condition and moisture deficit. The improved varieties were superior to the farmers' varieties in grain yield and other traits under moisture deficit, possibly due to selection of their progenitors for improved performance in multiple locations. We found some farmers' and improved varieties with similar yield potential and flowering time under well-watered conditions but with marked differences in grain yield and other traits under moisture deficit. Use of such promising landraces that would also be invaluable sources of desirable farmers-preferred end-use quality traits in combination with promising improved varieties as breeding materials could enhance the genetic grain from selection for drought tolerance in early maize.

The drought tolerance of immature embryos (17,5–20,0 days after artificial pollination) of a number of varieties and hybrid combinations of spring soft wheat was assessed. Donor plants were grown in the field during vegetation season 2018. The detection of drought resistance of immature embryos was conducted by their ability to give rise to a seedling developing to the phenophase of tillering in vitro in conditions simulating a moisture deficit. Moisture deficiency was achieved by introducing the PEG 6000 into composition of the nutrient medium MS. The embryos were incubated in the dark at +27 °C for 21 days. Conducted a visual assessment of morphological indicators of developing seedlings of regenerants to the phenological phase of tillering. The development of the seedling to the phenophase of complete grain ripeness in soil conditions ex vitro and the laboratory germination of the obtained grains were evaluated. The wheat genotypes, characterized by both the ability of immature embryos to form seedlings in the conditions of drought simulation and a sufficiently high laboratory germination of the obtained grains were revealed. These wheat genotypes can be recommended for use in the creation of drought-resistant hybrid lines and for their inclusion in the breeding process as initial forms.
