Abstract

The early QPM shaandan No.17 was bred by high lysine line Y77(female) and QPM line Y76(male) in special maize office, college of Agriculture, NWSTUAF From 2000 to 2002, the experiment results including regional test, production test in Huanghuihai areas. Showed it had good characteristic of muti-resistance, Lys 0.46%, Pro 11.53%, early mature (it was six days than Nongda 108), Yield as well as normal maize, food and feeding dual purpose. The shaandan No.17 was recommitted to be authorized by National Committee of Crop Variety. It is fit for growing in shaanxi Province and Huanghuihai areas where planting corn in spring, summer. Authors alternatively used backcrossing and selfed crossing as main heterotic pattern of normal maize combination way improved huangaisi×Lancaster line and introduced subtropical germplasm into the parents boarding the germplasm base. Its way was excel and crossing material was new. Shaandan No.17 was the first-rate normal maize, food maize, feeding maize respectively and the second-rate QPM and would be the new released QPM variety instead of main cultivars.
