研究2004~2013年吉林省审定普通玉米品种利用情况,对品种品质性状进行综合分析。研究表明,吉林省内单位育成品种较多,但缺少优良的“大品种”。玉米新品种主要由民营种业育成,科研院校等国营单位育种数量明显下降;中熟、中晚熟品种数量显著增加,晚熟品种的数量在逐年越少,品种广适安全的概念被强化。普通玉米淀粉含量逐年提高,蛋白质与脂肪含量呈缓慢下降趋势,赖氨酸含量和容重略有增加。
The research on the utilization of common maize varieties in Jilin Province from 2004 to 2013 was conducted to make a comprehensive analysis of the quality traits. Research shows that there are more bred varieties in Jilin Province, but lack of good “big breeds”. The new varieties of maize were mainly bred by private-owned seed breeding enterprises. The number of breeders in scientific research institutes and other state-owned units decreased significantly. The number of medium-late-maturing varieties increased significantly while the number of late-maturing varieties decreased year by year. The concept of wide variety and safety was strengthened. Normal corn starch content increased year by year, the protein and fat content showed a slow downward trend, lysine content and bulk density increased slightly.
