摘要
福建省4个病鉴点采用田间自然诱发鉴定长优2号对稻瘟病的抗性。结果表明,长优2号对叶瘟和穗颈瘟的抗性表现为抗(R)至中感(MS)之间,综合评价为中感;而对照Ⅱ优明86和Ⅱ优3301对叶瘟的抗性表现为感(S)至高感(HS)之间,对穗颈瘟的抗性均表现为高感(HS),综合评价为高感。说明长优2号对水稻稻瘟病的抗性明显优于对照Ⅱ优明86和Ⅱ优3301品种。
The resistance of Changyou 2 to rice blast was identified at four sites in Fujian Province by using natural infection in the field.The results showed that the resistance of Changyou 2 to leaf blast and panicle blast was between R and MS,comprehensive evaluation was MS;The resistance ofⅡYouming 86 andⅡYou 3301(CK)to leaf blast was between S and HS,their resistance to panicle blast was HS,comprehensive evaluation was HS.The resistance of Changyou 2 to rice blast was obviously better than that ofⅡYouming 86 andⅡYou 3301.
