摘要
在黔北地区一般栽培水平条件下对省内外选育的高产杂交水稻组合进行了鉴选。结果表明,准两优527产量最高(8371.5 kg/hm2),比Ⅱ优838增产13.53%,属于多穗型组合,且抗稻瘟病、纹枯病,抗倒伏性强。川丰5号产量居第二(7908.0 kg/hm2),比Ⅱ优838增产7.24%,属于大穗型组合,抗稻瘟病,抗倒伏性强。C优725、中优838、冈优177等较好。各参试品种可在黔北地区种植。该文还提出了加强抗性育种的建议。
8 hybrid rice combinations bred by Guizhou and other provinces were tested to investigate their yield and main agronomic characters under the common cultivation condition in Meitan county, Guizhou. The results showed that the yields of Zhunliangyou 527 with the multi-panicles and strong resistance to rice blast, sheath blight and lodging and Chuanfeng 5 with the heavy panicle and strong resistance to rice blast and lodging were 8371.5 kg/ha and 7908.0 kg/ha, 13.53% and 7.24% higher than CK （ 11 You 838） respectively, and 8 tested hybrid rice combinations can be planted in Meitan county. The authors suggested that the breeders should pay more attention to the diseas resistance in hybride rice breeding.
