对８个自育优质蛋白玉米自交系和８个同型普通玉米自交系研究表明，优质蛋白玉米在生长发育进程中，特别是在苗期，表现为苗小、苗弱，株高、穗位高明显降低。遗传分析表明，决定优质蛋白玉米生长发育进程中各性状遗传效应中，喇叭口期叶面积、叶面积增长速率、出叶速率加性基因效应和非加性基因效应均很重要，而其余几个生长发育性状主要受制于非加性基因效应。
Studies on 8 inbred lines of self-prizing high-quality protein maize and 8 inbred lines of common maize showed that high-quality protein maize showed small seedling, weak seedling, plant height and spike in growth and development, especially in seedling stage Bit high significantly lower. Genetic analysis showed that, in determining the genetic effects of various traits during the growth and development of high quality protein maize, the trumpet leaf area, leaf area growth rate, leaf rate additive and non-additive gene effects were all important, while the rest Growth and development traits are mainly affected by non-additive gene effect.
