1989～1990年对502份稻种资源进行了抗稻曲病鉴定。自然诱发及人工接菌的结果表明,品种(系)间抗、感反应差异明显;不同熟性品种(系)间的抗病性趋势表现为早熟>中熟>晚熟。
From 1991 to 1990, 502 rice germplasm resources were identified as resistant to rice smut. The results of natural induction and artificial inoculation indicated that there was significant difference in anti-resistance and anti-response among varieties (lines). The disease resistance trend of different varieties (lines) showed early maturity, medium maturity and late maturity.
