摘要：

水稻卷叶螟是影响水稻高产稳产的重要迁飞性虫害之一,培育具有抗（耐）虫性的品种对水稻卷叶螟的绿色防控具有重要意义,而筛选、鉴定抗（耐）虫亲本材料是抗虫育种的基础。从2015年起,连续4年分别在海南陵水县和四川泸县田间条件下,通过小区对比试验观察‘A232’及杂交后代‘泸恢317’、感虫对照‘F77’的单株卷叶率及群体卷叶率田间表现,并对供试材料间群体卷叶率差异进行显著性测验。结果表明：2015年感虫对照‘F77’的群体卷叶率为10.5%,分别比‘A232’及‘泸恢317’高8.0%及9.6%;2016年‘F77’的群体卷叶率为74.9%,分别比‘A232’及‘泸恢317’高20.3%及28.0%,2年的差异均达5%显著水平。2017年秋播的‘A232’、‘泸恢317’及‘F77’群体卷叶率均在90%以上,且它们间差异不显著(P>0.05)。但‘A232’及‘泸恢317’的0级叶率分别比‘F77’高4.4%及8.7%,1级叶率分别比‘F77’高11.7%及22.1%,3级叶率分别比‘F77’低16.0%及30.4%,它们之间的差异均达5%显著水平。泸县观察表明‘A232’及‘泸恢317’对稻显纹纵卷叶螟也表现出明显耐害性(P<0.05)。经过多年不同季节不同地点试验表明,‘A232’及杂交后代‘泸恢317’可作为水稻卷叶螟耐虫种质利用。‘A232’是一个中抗二化螟及三化螟并对稻纵卷叶螟及稻显纹纵卷叶螟具有耐害性的多抗种质。

Abstract:

Leaf roller is one of the most important insect pests that affect the high and stable yield of rice. It is of significance to screen and cultivate resistant (tolerant) varieties to conduct green control of rice leaf roller. Identification of resistant (tolerance) parents is the basis of insect-resistant breeding. From 2015, under the field condition in Lingshui County and Luxian County for 4 years, the responses of insect resistant ‘A232’, its progeny ‘Luhui 317’, and susceptible ‘F77’ to RLR and RSLR were observed through plot contrast test, respectively. The significant difference of leaf roll rate among the tested materials was tested. The results showed that the leaf roll rate of ‘F77’ in 2015 was 10.5%, 8.0% and 9.6% higher than that of ‘A232’ and ‘Luhui 317’, and the leaf roll rate of ‘F77’ in 2016 was 74.9%, 20.3% and 28.0% higher than that of ‘A232’ and ‘Luhui 317’, respectively. The difference of the two years reached 5% significant level. The leaf roll rate of ‘A232’, ‘Luhui 317’ and ‘F77’ of autumn sowing in 2017 was all above 90%, and their differences were not significant (P>0.05). However, the rate of grade 0 leaves of ‘A232’ and ‘Luhui 317’ was 4.4% and 8.7% higher than that of ‘F77’. The rate of grade 1 leaves of ‘A232’ and ‘Luhui 317’ was 11.7% and 22.1% higher than that of ‘F77’, the rate of grade 3 leaves of ‘A232’ and ‘Luhui 317’ was 16.0% and 30.4% lower than that of ‘F77’. The difference between them reached 5% significant level. ‘A232’ and ‘Luhui 317’ showed obvious tolerance to rice leaf roller in Luxian (P<0.05). After tests in different seasons and sites for years, ‘Luhui 317’ could be used as a variety to resist rice leaf roller. ‘A232’ is a variety that has moderate resistance to striped rice borer and tryporyza incertulas and has tolerance to rice leaf roller and rice stripe leaf roller.

Key words: rice, insect-resistant germplasm, rice leaf roller, rice stripe leaf roller, leaf roll rate, tolerance to insects
