Abstract

The height of rice is one of the important agricultural traits, which affects on the rice architecture and production directly. The investigation of the length of the uppermost internode showed that the elongation mutation of the first internode is controlled by a recessive nuclear locus. The gene is localized between the STS marker of E30531 and the CAPS marker of C903 on the long arm of chromosome 5, apart from 6.7 cM and 2.8 cM respectively. The fine localization maps the gene between 0.3 cM flanks, which will help clone this gene and study the mechanism of the gene function.

摘要

水稻株高是重要的农艺性状之一，直接影响水稻的株型和产量。对最上部节间长度的研究表明，第一节间的伸长突变受一个隐性核基因座控制。该基因定位在第5染色体长臂上的E30531的STS标记和C903的CAPS标记之间，分别相距6.7 cM和2.8 cM。精细定位将该基因定位在0.3 cM的侧翼区间内，这将有助于克隆该基因并研究其基因功能机制。
