吉林省玉米品种概况及品质现状分析

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。

Quality Status Survey and Analysis of Maize Varieties in Jilin Province

The utilization status of ordinary maize varieties that were audited by Jilin province during 2004-2013 was analyzed, and the quality traits were also studied. The results showed that there were more variety breeding research units in the province, but rarely plantings. New maize varieties were bred mainly by private seed industry, the breeding number of research institutions and other state-owned units was decreased significantly. The number of mid-maturing and late-maturing varieties increased significantly, and that of late-maturing varieties decreased year by year, and the concept of wide adaptability safety for variety was strengthened. The starch content of common maize had gradually increased, protein and fat content showed a downward trend, and lysine content and bulk density increased slightly.
