Breeding and Application of New Extra-early Maize Hybrid Tezao 2 |
| |
| Abstract: | 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. |
