在中非国家布隆迪高、中、低3个生态区开展了我国玉米杂交种的筛选,结果表明:与当地对照种相比,南校9665和云瑞6号2个品种在3个试验区平均增产38.1%和153.9%;南校18号在低、中海拔区增产38.1%、64.6%;农大95等3个品种在中、高海拔区增产率35.1%～130.5%;云瑞8号、南玉5号等12个品种在中海拔区增产31.7%～125.8%;迪卡008等3个品种在高海拔区增产41.3%～63.2%。来自我国南方及西南区选育的品种在当地适应性相对较好。引种品种在布隆迪非洲条纹病毒病疫区感病。此外,当地玉米种植技术落后,管理不科学,为发挥引进品种产量潜力需配套开发适应当地生产水平和种植方式的管理技术。
The screening of maize hybrids in three high, middle and low Burundi regions of Central African countries was carried out. The results showed that compared with the local control, two cultivars, Nanji 9665 and Yunrui 6, averaged over three experimental areas Increased by 38.1% and 153.9% respectively; South School No. 18 increased yield by 38.1% and 64.6% in middle and high altitude area in the low and middle altitude areas; increased yield was 35.1% -130.5% in middle and high altitude areas of Nongda 95; Jade 5 and other 12 cultivars increased yields by 31.7% ~ 125.8% in the middle-altitude area. Three cultivars including Dika 008 increased yields by 41.3% -63.2% in high-altitude areas. Varieties from South China and Southwest China breeding in the local adaptability is relatively good. The introduced species is susceptible to the stripe virus disease in Burundi. In addition, the local corn cultivation technology is backward and the management is unscientific. In order to give full play to the yield potential of the introduced varieties, the management techniques suitable for the local production level and planting methods should be developed in coordination with each other.
