抽穗期受光温资源和基因网络的共同调控,影响作物产量和品种的地域适应性,通过关联分析鉴定与抽穗期性状相关的显著位点和基因,对解析抽穗期的遗传基础具有重要意义。本研究按照双因素交叉式遗传设计（North Carolina design Ⅱ, NCⅡ）将115份籼稻品种作为父本, 5份不育系作为母本,进行测交,得到了575个F1代的测交群体。对亲本和F1代抽穗期的表型值、亲本品种群体的一般配合力、F1代群体的特殊配合力和超亲优势值进行全基因组关联分析,（1）共定位到104个关联位点,分布在12条染色体上。其中,第4条染色体上检测到的显著位点最多,为16个。在亲本的抽穗期表型、一般配合力、F1代的抽穗期表型、特殊...

Heading date is jointly regulated by light and temperature resources and gene network, affecting crop yield and regional adaptability of varieties. Identification of significant loci and genes associated with trait variation by genome-wide association analysis (GWAS) is of great significance to analyze the genetic basis of the heading date in rice. In this study, according to the North Carolina design II (NCII), 115 indica rice varieties as the male parents and 5 sterile lines as the female parents had been made test cross, and 575 F1 test-cros...
