杂交玉米“交三单交”,是“七五”期间贵州省农业干部管理学院用新育成的自交系“交51”作母本与优良自交系“330”作父本培育成的新杂交种。在三级区域试验中,经严格检验鉴定产量均名列第1位,表现抗性强,适应广,综合性状好,高产稳产。但因贵 Hybrid maize “pay three single cross”, is the “seven five” period of Guizhou province agricultural management school with the new bred inbred line “51” as the female parent and elite inbred line “330” Hybrids. In the third-level regional experiment, the yield was ranked No. 1 after strict inspection and identification, showing strong resistance, wide adaptability, good comprehensive characters and high and stable yield. But expensive
