| 中文摘要: |
| 以46份南方花生区试参试品种产量与主要品质性状在2011—2015年的调查数据为基础，分析连续5年花生主要品质指标与产量的变化趋势。结果表明，2011—2015年，参试花生的含油量与蛋白质含量均呈下降趋势，分别降低1.14%、2.06%。2012—2014年油酸含量出现小幅上升，由42.98%增长到45.5%，而亚油酸含量则表现出相反结果，但与2011年相比两者均未达到显著水平。综合分析不同品种间的品质性状变化，发现未对不同年份的变化趋势造成影响。产量分析表明，现阶段培育的品种总体表现为减产，由2011年的283.1 kg减少到2015年的251.6 kg，该结果不受品种间产量差异影响。2011—2015年间南方花生区试品种主要品质性状中的含油量、蛋白含量以及产量均呈下滑趋势，需被育种领域重视。 |
| 英文摘要: |
| Peanut （Arachis hypogaea L.） is a pivotal commercial oilseed crop in china，and peanut improvement breeding has focused much of its attention on quality traits and yield. In this study，we investigated the yield and major quality trait in national regional trail （NRT） peanut varieties in south china based on the data of agronomic traits collected in 2011-2015，and then analyzed the trend change of quality and yield in five consecutive years. Our results suggested that the contents of total oil content and protein content presented decreasing in regional experiments peanut varieties from 2011 to 2015，reduced 1.14% and 2.06%，respectively. The oleic acid content of all varieties exhibited increasing at the period of 2012-2014，and the value increased from 42.98% to 45.3%，but the content of linoleic acid showed non-significant opposite result at the same phase in comparison with 2011. Meanwhile，quality traits variation of different peanut varieties did not showed negative effect on trend vibration of different years by integrative analyzing the characters of the peanut varieties came from different breeding institution. In addition，most current breed peanut variety displayed a situation of decline via analyzing the trend vibration of yield in 2011-2015，the annual yield have decreased from 283.1kg to 251.6kg，and that never affected by the discrepancy between different NRT peanut varieties. Taken together，our study suggested that the majority quality，including oil content，protein content，and yield exhibited downward trend in 2011-2015，this result should be focused on breeding research；and our data was able to be used for providing theoretical guidance for cultivating peanut variety with high yield and good quality. |
