吉林省玉米品种容重浅析

Analysis of Maize Unit Weight in Jilin Province

选择吉林省目前生产中应用的140个玉米品种,分为早熟组、中熟组、中晚熟组、晚熟组、耐密组、高油组、青贮组和特用组共8组,在吉林省中部半湿润区、西部半干旱区设3个试验点,系统地研究了吉林省玉米品种容重概况,通过在生态区间、品种组间、品种组内计算与分析,获得了各品种的容重差异及容重显著高于对照的高容重玉米品种。

140 maize hybrids that were used in production in Jilin province at present were chosen and they were divided into eight groups, i.e., early mature maize, middle mature maize, middle-late mature maize, late mature maize, tolerant to high-density maize, high oil maize, ensiling maize, specialization corn group. Three sites were selected in the half moist district of the middle part of Jilin province and in the semiarid district of the west of Jilin province. Maize unit weight of Jilin province was systematically studied and the difference of maize unit weight among different ecological area, different varieties was analyzed. Maize unit weight of each varieties was obtained and varieties which maize unit weight was higher that that of the control was selected.
