The present paper dealt with the comparison of several varieties in the rate of sprouting seeds and the effect of fungicide coating on seed surface for preventing the seed rot, 1. The samples of 14 varienties were tested in November and February seedings and the respective rates of sprouting seeds were 36〜9% and 79〜43% on cropless fields, 21〜3% and 56〜26% between rows of barley and 19〜2% and 54〜18% between rows of wheat. Varietal difference showed the same tendency in each time of seeding and each field condition. 2. Negative correlation was shown between the rate of sprouting seeds and the germination speed, therefore the difference of dormancy in varieties is said to be related to the rate of sprouting seeds. 3. Coating of seeds with the fungicide showed the high effect on prevention of the seed rot, while it gave some injuries on roots of young seedlings. Accordingly, a proper dose of the fungicide for coating is required. 4. The rate of sprouting seeds in November seeding was raised with the combination selected varieties and the fungicide coating.
