高产高淀粉多抗玉米杂交种品玉3号的选育研究

Selecting and Breeding on Maize Hybrid Pinyu No.3 with High Yield,High Starch and Multiple Resistance

品玉3号是山西省农科院品种资源研究所以自选系293为母本,自选系383为父本,于2000年育成的玉米单交种。经多年试验示范表明,品玉3号比目前生产上应用的品种增产5%以上,具有增产潜力大、抗多种病害、淀粉含量高和制种产量高等特点,适宜在山西省春播中晚熟区及黄淮海夏播区种植。

Pinyu No.3 was bred by Instituten of Crop Germplasm Resources of Shanxi Academy of Agricultural Sciences in 2000,which was combined Pinxi 293 as female parent and Pinxi 383 as the male parent.Through several years trial and planting in different areas and conditions,the hybrid showed that Pinyu No.3 increased the yield of more than 5% comparing with the varieties used in production.h has the characteristies of good yield potential, multiple resistance,high starch and high yield of seed growing.It is suitable to spring planting in middle-late part of Shanxi province and summer planting in Huanghuihai area of China.
