Drought-resistant Germplasm Screening and Drought-resistance Mechanism in Proso Millet

Through the repetitious drought-making method, 500 accessions of representative proso millet germplasm from Shanxi province have been identified and drought-resistance evaluated.9 accessions of germplasm are screened as class 1,high-class drought-resistant germplasm.For these high-class drought-resistant germplasm,the drought-resistance physiological index,stomatal conductance,transpiring rate and photosynthesizing rate measurements in farm and water content measurement of unorganized leaf in lab have been completed, which further proves that the repetitious drought-making method is reliable and feasible for the drought-resistance identification and evaluation of large quantities of Proso millet Germplasm,as well as,discloses the drought-resistance mechanism of Proso millet germplasm.
