摘要
采用回归异质性测验法分析了黑龙江省８个玉米杂交种抽丝后３０～６０ｄ期间百粒重的变化。结果表明，此期间早熟和晚熟杂交种百粒重变化的回归系数差异显著，因而平均灌浆速率也有显著差异。
The difference on 100 kernel weight in 30～60 days after silking in 8 maize hybrids was analysized in Heilongjiang Province by the method of regression heterogeneity analysis There existed significant difference in filling rate among the hydrids tesed according to their regression coefficients during this period
