水稻产量事关粮食安全,对水稻高产基因的进一步挖掘意义重大。本研究采用花药培养技术,构建了包含101个株系的中嘉早17×D50的加倍单倍体群体(DH群体)。考察海南陵水、浙江杭州高产田块和杭州山区低产田块3种种植环境下DH群体各株系、亲本中嘉早17和D50的有效穗数、每穗粒数、结实率以及千粒重等产量相关性状,同时构建DH群体的遗传连锁图谱。QTL定位分析表明, 3种种植环境下共检测到74个具有显著加性效应的QTL,其贡献率变幅为3.7%~43.2%,分布于水稻12条染色体。其中, qPH1-1和qFLL12在3种种植环境下均被检测到,其贡献率分别为8.9%、24.2%、43.2%和16.6%、17.9%、18.9%。此外, qPH3、qFLL10-2、q...

Rice yield has obvious effect on national food security. The further excavation of high yield related genes is of great significance. In this research, a doubled haploid population (DH population) of Zhongjiazao 17 (YK17) × D50 was constructed by using the anther culture technique. The yield related traits including effective panicles per plant, grain number per panicle, seed setting rate and 1000-grain weight in three different planting environments (Lingshui, Hainan planting environment, high yield field in Hangzhou planting environment, low...
