糯稻品种的抗性评价与利用

我们从1977～1992年计14年，采用网笼育苗接虫鉴定与田间自然诱发，共鉴定国内外水稻品种（包括株系，杂交稻三系）32000多份，筛选出高抗至中抗稻飞虱的材料3247份，占11．44％，并从中评选出产量高，适应性广，糯性好，能抗褐飞虱、白背飞虱、稻瘟病、白叶枯病等多抗性的糯稻新品种，其中以“水源290”及“三五糯”表现最好。在湖南作双季晚稻亩产在420～550kg，作中稻在135～621kg。农民反映糯性好，抗性强，出米率，出酒率，做糍粑，年糕均优于其他糯稻品种。

Evaluation and utilization for resistant varieties of glutinous rice

During 1977-1992, more than 32000 varieties or lines of domestic and overseas (includingkybrid rice materials) were screened for insect resistance to the planthopper by using greenhousescreening and field screening. Of these, 3247 varietics or lines with insect resistance were evaluated.The glutinous rice Shuiyang-290 and Sanwu-glutinous showed a good resistance not only to the planthopper but also to the rice blast and the rice bacterial blight. The Sanwuglutinous can producegrain of 420 to 550kg/mu in double cropping rice and 430 to 620kg/mu in single cropping rice.
