摘要
1995～1997 年对47 份粳稻新品种(系),包括江苏省大面积推广的粳稻品种以及外省征集的部分品种(系)进行网室抗三化螟测定和田间抗虫性调查,从中评选出1 个中抗品种,4 个耐螟性较好的品种(系)。并对抗螟性机理进行了探讨,提供育种和生产部门参考。
In 1995~1997, fourty seven new Japonica varieties (lines), including released varieties in Jiangsu province and some varieties (lines) from other provinces were investigated and evaluated for their resistance to yellow rice borer [ Tryporyza incertulas (walker)] in the fields.
