| 摘 要： | 以辽宁省中晚熟水稻新品系为试验材料,以辽粳9号为对照,对辽宁省中晚熟水稻新品系的产量及其产量构成因素进行了研究。结果表明:辽宁省中晚熟水稻新品系株高大多在95~105 cm。平均产量为623.81kg/667m2,比对照增加6.45%。平均穗数、平均穗粒数和平均千粒重高于对照,平均结实率平均低于对照。穗粒数与千粒重呈显著负相关,千粒重与结实率呈极显著正相关,结实率与产量的相关性未达到显著水平。

| Abstract: | New mid-late rice varieties in Liaoning as materials, with Liaojing 9 as control could be used to study yield and yield components.The results showed that new mid-late rice varieties in Liaoning mostly in plant height between 95～105 cm. The average yield is 623.81 kg/667m~2, increased 6.45% compared with the control.Mean panicles ,mean grains per panicle and mean 1000-grain weight were higher than the control. Mean seed setting rate was lower than the control. There was significantly negative correlation between grains per panicle and 1000-grain weight at 0.05 level. There was significantly positive correlation between 1000-grain weight and seed setting rate at 0.01 level. There was no significant difference between seed setting rate and yield. |
