为了分析不同年份、不同产地生产的种子对超甜玉米发芽率、田间出苗率、单穗重及产量的影响，以‘迪甜6号’为试验材料，对3个年份（A1为2010年，A2为2011年，A3为2012年）、2个产地（B1为平遥，B2为海南）生产的种子进行了室内发芽试验和田间测定。结果表明：种子生产年份对种子发芽率、田间出苗率、单穗重、产量4个指标影响较大；除产量外，种子产地对其他3个指标影响不是很大。‘迪甜6号’的种子发芽率和田间出苗率随着种子生产年份的久远均呈现下降趋势。种子生产年份各处理间发芽率和田间出苗率存在极显著差异，种子生产地点各处理间发芽率和田间出苗率无显著差异；2个处理间交互作用不明显。种子生产年份、产地对单穗重影响不是很大，各处理单穗重依次为A3B1>A3B2>A2B2>A1B2>A2B1>A1B1。种子生产年份与产地对产量的影响达极显著水平，2个处理间交互作用显著。处理A3B2产量最高，为14235 kg/hm2。‘迪甜6号’田间出苗率与发芽率呈极显著正相关；产量与种子发芽率、田间出苗率、单穗重均呈极显著正相关。

In order to analyze the influence of seeds which were produced in different years and places on the germination rate, the field emergence rate, the weight of single ear and yield in super sweet corn, the authors took‘Ditian6’as the tested material for the study. Its seeds that produced in three years (A1 2010, A2 2011, A3 2012) and two places (B1 Pingyao, B2 Hainan) were used for indoor germination experiment and field measurement. The results showed that seed production year saw greater impact on the four indexes, which were the seed germination rate, the field emergence rate, single panicle weight and yield. In addition to yield, effects of seed origin on the other three indicators were not great. The seed germination rate and field emergence rate of‘Ditian6’showed a downward trend with seed produced more years before. The germination rate and field emergence rate are highly significant different among three treatments of seed production year. But the germination rate and field emergence rate had no significant difference between two treatments of seed production site. Interaction of the two treatments was not obvious. Seed produced in different years and places hadn’t great influence on the weight of single ear. The single panicle weight of different treatments were in order as A3B1>A3B2>A2B2>A1B2>A2B1>A1B1. Effect of seed production year and origin on yield reached extremely significant level. Significant interactive effects between two treatments were obtained. Treatment A3B2 had the highest yield of 14235 kg/hm2. For‘Ditian6’, the field emergence rate and germination rate were positively correlated. What’s more, yield and seed germination rate, field emergence rate as well as single panicle weight of‘Ditian6’were positively related.
