摘　　要：对沈单7号、沈单10、沈玉21等10个玉米杂交种及其亲本自交系的雄穗分枝数、雄穗长度和重量等性状进行研究。方差分析和相关分析表明,杂交种及其亲本自交系雄穗分枝数和雄穗长度对肥力的反应差异不显著,雄穗重量对肥力的反应极显著,肥力与亲本自交系间雄穗重量的交互作用差异显著。在不追施氮肥的条件下,雄穗分枝数和雄穗重量与子粒产量间呈显著负相关,雄穗重量与雄穗分枝数间呈极显著正相关;在追施氮肥的条件下,雄穗分枝数与产量间呈显著负相关,雄穗重量与雄穗分枝数间呈极显著正相关。The research of tassel branches, tassel weight, tassel length on 10 Shenyu series maize hybrids and its parental inbreds were studied. According to variance analysis and correlation analysis, the results showed that the effects of topdressing urea on branches and length of tassel of Shenyu series maize hybrids and its parental inbreds were not significant. But effect of that on tassel weight of Shenyu series maize hybrids was significant. The interaction between fertilizer and parental inbred lines was extr...
