利用粳稻日本晴×籼稻Kasalath回交自交系获得的23个重要生理和农艺性状（包括13个新测定性状）的QTL定位结果，构建了水稻功能图谱。利用这些材料，水稻基因组计划（RGP）开发了一个高密度的遗传图谱。控制产量的QTL与控制光合能力等与产量相关的形态和生理性状的QTL没有重叠。这一结果表明，这些性状不影响产量，至少在这种遗传背景和环境。控制产量的QTL也没有重叠的结构基因控制碳代谢（rbcS，胞质或质体果糖-1，6-二磷酸，R-酶，蔗糖合成酶）。功能图和来自RGP的结果的组合可以是有利的。讨论了该地图的实用性。
We have constructed a rice function map by collating the results on quantitative trait loci (QTLs) for 23 important physiological and agronomic characters (including 13 newly measured traits) obtained using backcross inbred lines of japonica Nipponbare x indica Kasalath. Using these materials, The Rice Genome project (RGP) has developed a high-density genetic map. QTLs controlling yield did not overlap with those controlling the morphological and physiological traits supposed to relate to yield, such as photosynthetic ability. This result suggests that these traits do not influence yield, at least in this genetic background and environment. QTLs controlling yield also did not overlap with the structural genes controlling carbon metabolism (rbcS, cytosolic or plastidic fructose-1,6-bisphosphate, R-enzyme, and sucrose synthase). The combination of a function map and results from the RGP can be advantageous. The utility of this map is discussed.
