摘　　要：特早2号是以自选系太早1001作母本,R综57-3作父本组配而成的玉米杂交种。该品种属特早熟品种,需≥10℃积温2 300℃左右,播种生育期90～95 d。2009—2010年在各级各类区域试验中表现为早熟、高产、优质、抗病、抗倒、高淀粉和耐深播。适宜春播特早熟区种植,种植密度以60 000～67 500株/hm2为宜,制种时父母本同期播种。The new maize hybrid Tezao 2 was bred by cooperation of institute of crop Science and modern agriculture research centre of Shanxi academy of agricultural sciences. It was combined with two inbred lines Taizaol001 and Rzong57-3. Tezao 2 was an extra-early maturing hybrid. It needed accumulative temperature 2 300℃（≥10℃）. The hybrid showed high yield at various experiment plots in different areas in 2009--2010. The result showed that it had earliness, high yield, high quality, high disease resistance, lodging resistance, high starch and deep-seeding tolerance. The plant populations were 60 000- 67 500/hm2 and the male and female were sowed in same period when seed was produced.
