种子活力是种子质量的一个重要特征，并且有强壮的种子活力的大米栽培变种在为最佳看台建立的直接播种的大米生产是合乎需要的。在现在的学习，为米饭种子活力的三个特点的量的特点 loci ( QTL )包括萌芽率，在萌芽阶段期间，最后的萌芽百分比，和萌芽索引，用生来的线( RIL )人口从在装饰用的梨树 Daguandao 和 indica IR28 之间的一个十字导出的一 recombinant 被调查，并且用印射的多重间隔( MIM )来临。结果证明 indica 大米比装饰用的梨树大米在萌芽阶段期间介绍了更强壮的种子活力。十 QTL 的一个总数，和至少五新奇等位基因，被检测控制单个 QTL 解释的变化(R 2 ) 的米饭种子活力，和数量从 7.5% ～ 68.5%，与有 R 2 的三主要 QTL >20% 。大多数这里检测的 QTL 是可能的为种子重量，种子尺寸，或种子休眠与 QTL 与一致，建议大米种子活力可能与种子重量，种子尺寸，和种子休眠被相关。至少五 QTL 是没有在米饭，和主要的那些的种子活力基因的以前的报告的新奇等位基因或次要的 QTL 能被用来显著地在米饭由帮助标记的选择(妈) 改进种子活力。

英文摘要：

Seed vigor is an important characteristic of seed quality, and rice cultivars with strong seed vigor are desirable in direct-sowing rice production for optimum stand establishment. In the present study, the quantitative trait loci （QTLs） of three traits for rice seed vigor during the germination stage, including germination rate, final germination percentage, and germination index, were investigated using one recombinant inbred line （RIL） population derived from a cross between japonica Daguandao and indica IR28, and using the multiple interval mapping （MIM） approach. The results show that indica rice presented stronger seed vigor during the germination stage than japonica rice. A total of ten QTLs, and at least five novel alleles, were detected to control rice seed vigor, and the amount of variation （R2） explained by an individual QTL ranged from 7.5% to 68.5%, with three major QTLs with R2〉20%. Most of the QTLs detected here are likely to coincide with QTLs for seed weight, seed size, or seed dormancy, suggesting that the rice seed vigor might be correlated with seed weight, seed size, and seed dormancy. At least five QTLs are novel alleles with no previous reports of seed vigor genes in rice, and those major or minor QTLs could be used to significantly improve the seed vigor by marker-assisted selection （MAS） in rice.
