| 摘 要： | 利用近二十年河南省南部组区域试验数据，对新育成品种的主要农艺性状演变规律进行了分析，结果表明：随着品种育成年份的延后，抽穗期和成熟期呈提前趋势；株高呈降低趋势；全生育期天数和每亩有效穗数呈减少趋势；灌浆时间、穗粒数、千粒重和亩产量呈增加趋势。相关性分析表明，产量与千粒重、穗粒数呈显著正相关，与成熟期呈极显著负相关，说明产量的提高主要是与穗粒数和千粒重增加有关。 |

| Abstract: | The 20-years’ experimental data from Southern Wheat Group of Henan Regional Trial were used to study the evolution law of main agronomic traits of southern wheat varieties. The results showed that, with the postpone of released year of variety, the heading date and maturation stage moved up, the plant height reduced, whole growth period and the ear number/mu decreased, grain-filling period, the grain number per ear, 1000-kernal weight and grain yield per mu increased. The correlation analysis showed that the grain yield had significantly positive correlation with 1000-kernal weight and the grain number per ear , while had significantly negative correlation with maturation stage.which indicated that the improvement of grain yield was mainly due to the increase of 1000-kernal weight and grain number per ear . |
