优质高产玉米新品种晋单80号的选育

摘要

Coin single-cross variety Jindan 80 was bred by inbred-line T14-3B (female) and 295 (male) in Institute of Maize, Shanxi Academy of Agricultural Sciences in 2003 as a medium earliness hybrid. According to Shanxi variety pre-teat, regional test, production test and quality analyses, Jindan 80 could be adapted to different colonial densities. The plant population was 49 500 - 52 500 seedlings/hm2, and it could be 52 500 ~ 60 000 seedlings/hm2 in high yield field. Jindan 80 has the characteristics of high yield, fine quality, multiple-resistance, wide adaptation and high yield seed propagation and so on.%晋单80号是山西省农业科学院玉米研究所2003年以自选系T14-3B为母本、自选系295为父本杂交选育而成的中晚熟玉米新品种.根据山西省预试、区试、生产试验和品质分析结果,该品种种植可稀可密,稀植一般49 500～ 52 500株/hm2,密植可达52 500～ 60 000株/hm2;具有高产、优质、抗病、抗倒、抗旱、耐瘠、适应性广、制种产量高等特点.
