摘要:

水稻是我国最重要的粮食作物之一，提高其产量一直是水稻育种家的不懈追求。水稻种子活力是一个重要的农艺性状，与产量和品质等性状密切相关。因此，开展水稻种子活力关键基因挖掘，选育高种子活力的水稻品种，对我国目前水稻直播栽培模式的推广应用，保障直播稻安全生产具有重要意义。全基因组关联分析(GWAS)是利用全基因组范围内大量的分子标记，以连锁不平衡(LD)为基础，用于研究动植物复杂数量性状遗传基础的一种高效方法。近年来，利用GWAS解析水稻种子活力自然变异的遗传基础取得了一定的进展。本文归纳了水稻种子活力表型鉴定的主要4类指标，概述了GWAS技术的研究优势及一般研究策略，重点介绍了近年来基于GWAS定位的水稻种子活力相关数量性状基因座(QTLs)及鉴定的10个水稻种子活力关键基因。最后，对目前GWAS解析水稻种子活力遗传基础存在的不足进行了剖析，并对今后种子活力相关性状的遗传研究提出了一些建议，以期为未来利用分子设计育种提高水稻种子活力提供理论参考。
