摘　　要：对铁岭市农业科学院近20年审定的15个铁粳系列水稻品种的产量及产量性状进行了试验分析。已审定水稻品种分中早熟和中熟2个生态类型,品种审定年均数量稳中有升,育种方法主要是常规杂交。产量表现为中熟组平均产量显著高于中早熟组平均产量。产量与以往相比有较大进步,但距全国近期平均水平仍有较大差距。水稻产量性状间存在着复杂的相关关系,株高与生物产量呈显著的正相关,每667m2有效穗数与产量呈正相关,每穗粒数与产量呈极显著正相关。产量性状协调发展是提高产量的有效途径。An experimental analysis was conducted on the yield and yield characteristics of 15 Tiejing rice va-rieties approved by the Tieling Academy of Agricultural Sciences in the past 20 years.Tieling Academy of Ag-ricultural Sciences has approved that rice varieties can be divided into two ecological types,medium early ma-turity and medium maturity.The annual average number of varieties approved has steadily increased.The breeding method is mainly conventional hybridization.The average yield of the midmaturing group was signifi-cantly higher than that of the mid early maturing group.The output has made significant progress compared to the past,but there is still a significant gap from the recent national average.There is a complex correlation be-tween rice yield traits,with a signficant positive correlation between plant height and biological yield,a posi-tive correlation between the number of effective panicles permu and yield,and a very significant positive corre-lation between the number of grains per panicle and yield.Coordinated development of yield traits is an effec-tive way to improve yield.
