Limited genetic variation in cultivated rice is a major factor responsible for the declining rates of yield improvement since the Green Revolution. Substantial and underexploited genetic variation exists within wild relatives of rice that improve tolerance to stresses. We will initiate the first program to mix alleles from all wild-rices, select those with benefit under stress and introduce them into cultivated rice. To date, alleles from individual non-domesticated rice species have been combined into elite varieties. While useful, this is both limited in scope and ignores much of the uncharacterized allelic variation present in wild-relatives. Furthermore, combining genomes can produce desirable phenotypes in progeny that are absent in parents. This breeding program will be underpinned by analysis of the genomes of the lines that we generate and by phenotyping to assess how each line responds to a wide range of stresses. The germplasm that we generate will be supplied to partners in Africa and India for testing in field sites, and to allow speedy supply of good seed to farmers.

栽培稻有限的遗传变异是绿色革命以来产量提高速度下降的主要原因。在水稻的野生亲缘植物中存在着大量未充分利用的遗传变异，这些变异可以提高水稻对胁迫的耐受性。我们将启动第一个项目，混合所有野生稻的等位基因，选择那些在胁迫下有益的等位基因，并将它们引入栽培稻。到目前为止，来自个别非驯化水稻物种的等位基因已经组合成优良品种。虽然有用，但这在范围上是有限的，并且忽略了野生近缘种中存在的许多未表征的等位基因变异。此外，组合基因组可以在子代中产生在亲本中不存在的期望表型。该育种计划将通过分析我们产生的品系的基因组和表型来评估每个品系如何应对各种压力。我们产生的种质将提供给非洲和印度的合作伙伴，在田间进行测试，并迅速向农民提供优质种子。
