Abstract: For knowing ordinary varied regular of corn yield of Hebei province and making clear aim and prospect ofbreeding in the future, The model of GM( 1, 1) of grey system through analysis regional experiment yield of corn variet ieswhich were approved by Hebei variety committee. A predictable model of the occurring of corncs develope: ^X ( 1)( k+ 1) =324 818. 583 945e0. 018524- 318 652. 083 945 was formulated, model to forecast the corn produce of Hebei province productionunder the conditions of relat ive stability of all its relevantelements and to provide scientific information for productionplanning and decision making.The forecast result indicated, Under the situating which excavates productive potentialof cultivable and non cultivable land resources and improves overall productivity of agricultural resources, HebeiProvincecs corn yields at 2030 year will possibility achieve 15 052. 6 kg/ hm^2.
