| 摘 要： | 对水稻品种抗褐飞虱不同生物型与其主要农艺性状的关系研究结果表明,水稻品种抗褐飞生物型Ⅱ与分蘖力相关显著,与始穗期、抽穗期、齐穗期、生育期、株高、有效穗、穗粒数、结实率、千粒重相关不显著。水稻品种抗褐飞虱孟加拉型与始穗期、抽穗期、齐穗期、有效穗相关显著;与生育期相关极显著;与分蘖力、株高、穗粒数、结实率、千粒重相关不显著。

| Abstract: | In this paper, relationships between resistance of rice varieties to different brown planthopper(BPH) biotypes and agronomic traits of rice were studied. The results indicated that resistance of rice varieties to BPH biotype Ⅱ were significantly related to tillering capacity and not significantly rekted to early heading period, heading period, full heading period, growth period, plant height, effective panicles, spikelets per panicle, seed setting rate, 1000-grain weight. Resistance of rice varieties to BPH Bangladesh were not significantly rekted to tillering capacity,plant height, spikelets per panicle, seed setting rate, 1000-grain weight, but significantly related to early heading period、 heading period、 full heading period and effective panicles in particular growth period. |
