- 摘要:
- 籽粒的大小和形状是影响水稻产量和稻米品质的主要性状。在基因GS3序列分析的基础上，对该基因第2外显子A/C和第5外显子13 bp Indel的2个变异位点分别开发功能标记，并将其用于294份水稻微核心种质和2007—2013年江苏省审定的65份粳稻品种的基因型鉴定。研究结果表明，第2外显子的A/C变异在籼粳亚种中有着相似的分布频率，并且都对粒长、粒厚和长宽比有极显著的影响。相对于基因型C而言，基因型A在籼粳亚种中都有更长的粒长、更薄的粒厚和更大的长宽比。但是第5外显子的13 bp 缺失变异只在粳稻中极低频率(074%)出现，属于稀有变异类型，比13 bp插入变异有着更短的粒长和更小的长宽比。这些研究结果为水稻产量和品质育种中充分利用基因GS3的优异等位基因奠定了基础。
