1986-1993年作者对省内外20多个单位提供的16m余份(次)品种,进行了稻瘟病、白叶枯病稻曲病、褐飞虱、白背飞虱的多抗性人工接种和自然诱发鉴定。筛选出早恢C98、IR64、70015、皖恢9号、76~27A等品种(系)可作抗病亲本利用。陆伍红、早籼240、59024扬稻4号、E164、广香40、当优9号、80优9号等品种表现高产,抗性也较好。本文还对水稻品种不同生育期发病关系、抗性鉴定接种方法和杂交水稻抗性遗传进行了初步分析。
In 1986-1993, the authors carried out multi-resistant artificial inoculation and natural induction of rice blast, rice brown leaf blight, brown planthopper and white-backed planthopper in 16 m varieties provided by more than 20 units inside and outside the province. Identification. Screening early restore early C98, IR64, 70015, Anhui Hui 9, 76 ~ 27A and other varieties (lines) can be used as resistant parents. Luwuhong, indica rice 240,59024 Yangdao 4, E164, Guangxiang 40, Dangyou 9, 80 9 and other varieties of superior performance, resistance is also better. The paper also analyzed the relationship of rice varieties at different stages of development, resistance identification of inoculation methods and hybrid rice resistance genetic analysis.
