The purpose of this research is to characterize African (Oryza glaberrima) and Asian (0. saliva) rice parents with their interspecific progenies developed in West Africa Rice Development Association (WARDA) in terms of dry matter production, grain yield and weed competitiveness.1) The African rice parent showed extremely high leaf area that aided superior vegetative growth compared with Asian rice, and the progenies showed the intermediate values. The CO2 exchange rate (CER), however, was lower in African rice compared with Asian rice. The progenies showed more erect leaves compared with African rice which has droopy leaves.2) Fast development of leaf area in African rice led to fast ground cover, so that African rice produced two times greater dry matter under low weeding level, and 1.3 times higher grain yield than Asian rice. African rice showed the lowest yield reduction due to no weeding by 30%against 50% in Asian rice.3) African rice produced significantly greater root dry weight than Asian rice. The progenies produced the intermediate amount. On whole plant dry matter basis water use efficiency (WUE) was higher in African rice than Asian rice and the progenies. It was concluded that during moderate level of water stress greater water extraction capacity in African rice gave more importance for the maintenance of better crop growth4) Average leaf area and dry matter production of African rice cultivars was found to be higher than the Indica and Japonica type cultivars due to the inoculation of mix-cultured rhizobacteria. The results have shown that African rice cultivars could produce better interaction with the free-living rhizobacteria.

本研究的目的是描述非洲（Oryza glaberrima）和亚洲（0。结果表明：（1）非洲水稻亲本的叶面积极高，营养生长上级，后代的叶面积居中。然而，非洲水稻的二氧化碳交换率（CER）低于亚洲水稻。后代叶片直立，而非洲水稻叶片下垂。2）非洲水稻叶面积发展快，地面覆盖快，因此非洲水稻在低除草水平下的干物质产量是亚洲水稻的两倍，籽粒产量是亚洲水稻的1.3倍。非洲水稻因不除草而减产幅度最小，为30%，而亚洲水稻为50%。3）非洲水稻根干重显著高于亚洲水稻。后代产生中间量。在全株干物质基础上，非洲稻的水分利用效率（WUE）高于亚洲稻及其后代。结果表明，在中度水分胁迫条件下，非洲水稻具有更强的吸水能力，这对维持作物生长具有重要意义。4）非洲水稻品种的平均叶面积和干物质生产高于籼型和粳稻型品种，这是由于接种了混合培养的根际细菌。结果表明，非洲水稻品种能与自由生活的根际细菌产生更好的相互作用。
