摘　　要：以晚粳光身稻新品系嘉64为供体亲本,用毛叶晚粳品种嘉33和嘉991作为受体亲本,分别转育成光身稻近等系NIL-33、NIL-991。分别在浙江嘉兴和海南陵水对这些品系进行了病虫害人工接种及自然发病情况的调查,研究了光身稻与病虫害发生的相关性。结果表明:水稻病虫害发生只与品种所具有的抗性基因有关,而与光身特性无关。The late japonica glabrous rice new line Jia 64 was used as donor parent, the late japonica hairy rice varieties Jia 33 and Jia 991 were used as acceptor parents, and the near-isogenic lines （NILs） NIL-33 and NIL-991 of glabrous rice were bred through hybridization respectively. Then, the NILs and their recurrent parents were planted in Jiaxing, Zhejiang and I,ingshui, Hainan, and the correlations between glabrous rice and the occurrence of pest insects and diseases were investigated by means of ar-tificial inoculation and natural disease investigation. The results showed that the occurrence of pest insects and diseases in rice relat-ed only to the resistant genes in cultivar, and it was independent of the smooth characteristic itself.
