| 摘 要： | 1985～1987年,本实验鉴定了4298份水稻叶瘟和穗颈瘟抗性。结果表明,叶瘟0～3级和8～9级材料,叶瘟抗性与穗颈瘟抗性高度相关,叶瘟4～7级材料,叶瘟抗性与穗颈瘟抗性无相关。对20个抗性不等的水稻品种分别用人工接种后,加盖尼龙薄膜方法和早晚播法,进行叶瘟抗性鉴定,结果基本一致。旱田晚播鉴定法可用于杂交后代抗稻瘟病鉴定,以减轻育种工作的压力。

| Abstract: | 4298 rice cultivars/lines were tested in 1985～1987 for resistance to leafand panicle blast by artificial inoculation then covened with plastic film.The results indicated that the resistances to leaf blast and panicle blast werehighly correlated(r=0.8939)when the severity index of leaf blast wasgrades 0～3 and 8～9.But if it was grades 4～7,the resistances to leaf blastand penicle blast were not correlated(r=0.0003).20 rice cultivars various resistances were tested by artificial inoculationand then covered with plastic film,and by late sowing on dry plot.Thetwo results were much the same.Therefore the late sowing method may beused to test the resistance of hybrids to rice blast. |
