采用直线相关分析方法，对１９８７～１９９７年江苏省淮南片小麦区域试验盐城点各参试品种的产量及其亩穗数、穗粒数、千粒重、穗重、株高等进行了分析研究。提出了沿海地区小麦育种亩产４００～５００ｋｇ适宜育种目标为：亩穗数３５万左右，穗粒数３５粒左右，千粒重４０ｇ左右，株高８５～９５ｃｍ，株型较紧凑，抗逆性强。
The linear correlation analysis was used to analyze the yield, acreage, grains per spike, 1000-grain weight, panicle weight, plant height of the tested varieties from 1987 to 1997 in Huainan slice wheat regional trial in Yancheng, Jiangsu Province. Proposed breeding of 400 ~ 500kg per mu of wheat breeding in coastal areas is as follows: the number of per mu is about 350,000, the number of grains per ear is about 35, the weight of thousand kernel is about 40g, the height of plant is 85 ~ 95cm, the plant type is compact and the resistance is strong.
