摘　　要：在山东省济宁市任城区进行14个粳稻新品种(系)的比较试验,对参试品种的农艺性状、产量、抗性及稻米品质表现进行汇总分析。结果表明,14个品种的生育期变辐为145~168 d,金稻919、津原985和津原U99表现早熟,垦稻808、豫农粳12、豫稻16熟期偏晚;14个品种产量介于513.0~740.7 kg/667m^2,津粳优2186产量最高,达到740.7 kg/667m^2;金稻939、金稻919米质达到优质1级,金粳818、津原U99、豫稻16达到优质2级,圣1712、圣稻3466除直链淀粉含量指标外,其他指标均达到优质2级以上。试验初步掌握14个育成品种(系)的特征特性和适应性,为济宁麦茬稻区种植优质高产粳稻品种提供参考依据。Fourteen new varieties(lines)of japonica rice were studied in a field trial carried out in Rencheng District,Jining City,Shandong Province in 2019;they were evaluated with respect to agronomic characters,yield,field resistance,and grain quality.The results showed that the growth periods of the 14 varieties varied from 145 to 168 days,of which three(Jindao 919,Jinyuan 985,and Jinyuan U99)were early maturing varieties,while another three(Kendao 808,yunnongjing 12,and Yudao 16)were late maturing varieties.The yields of the 14 varieties ranged from 513.0 to 740.7 kg/667m^2;of them,Jinjingyou 2186 attained the highest yield,reaching 740.7 kg/667m^2.In terms of grain quality,two varieties(Jindao 939 and Jindao 919)reached the first grade;three varieties(Jinjing 818,Jinyuan U99,and Yudao 16)reached the second grade;and the varieties Shengdao 1712 and 3466 reached the second grade in all indexes except for amylose content index.The above results lay foundations for selecting the japonica rice varieties that have high grain quality and a high-yielding ability,and are suitable for growing after wheat in southern Shandong Province.
