Screening method for germplasm resources of deep-sowing resistant rice

摘要: The invention provides a screening method for germplasm resources of deep-sowing resistant rice. comprises the steps material collection, seed screening, preparation before sowing, culture and measurement an emergence rate seedling height indexes; with no less than 50% 5 cm as standards, which do not meet standards are determined to be deep sowing. According method, 40-mesh sieved fine soil weighed by balance precision 1% is utilized under soil, certain amount water measuring cylinder, consistency test improved; different weights serve cover representing sowing depths, compared mode depth ruler, accuracy ensured.
