| 摘 要： | 以5份水稻籼粳种质作对照，对15份引进早稻种质的类缘关系进行分析。结果表明，2份早稻种质属于籼稻，5份偏籼，4份偏粳，4份粳稻。对这些早稻种质的主要农艺特征进行了测验；并对其产量构成因子相关性作了分析。单株产量与7个穗部数量性状的相关性分析表明：单株产量与穗总粒数、结实率和穗数相关极显。与穗长相关显；早稻陆引46、IRAT l04、巴西陆稻、早稻297等4份引进种质综合农艺性状较好，单株产量较高，值得进一步种植观察。

| Abstract: | The affinity of 15 accessions of introduced upland rice germplasm was analyzed with typical Keng and Hsien rice germplasms as controls. The results showed that 2 of the accessions were of Hsien type, 5 of partial Hsien type, 4 of partial Keng type and 4 of Keng type. The 15 accessions were examined in terms of main agronomic traits and correlation between yield per plant and 7 agronomic characteristics (quantitative features). Results indicated that the yield per plant was remarkably correlated to the total amount of grain per spike and setting rate and was correlated to the spike length. |
