Background
Most of corns in China are planted on dry lands in northeast, northwest, southwest and northwest, and drought often occurs during sowing. Although the corn requires less water from germination to emergence (only 3.1-6.1% of the total water demand), it is most sensitive to moisture during this period (delrin et al, 1983). Drought stress in the germination period can cause seedling growth obstruction, weak bud potential, less rooting amount, short root, weak seedling and low survival rate, and can seriously affect the growth and development of the seed particles and the final yield. In recent years, along with the rapid promotion of a mechanical single-seed sowing technology, the drought resistance of corn seeds in the germination period is particularly important. The drought-tolerant variety in the planting germination period is an effective measure for enlarging the arable area of a drought area and ensuring the whole seedling to ensure stable yield or increase yield. The development of drought-tolerant character screening and drought-tolerant evaluation is the key for screening drought-tolerant resources and breeding drought-tolerant varieties. Therefore, the development of drought tolerance identification of the corn germination period has extremely important significance.
