Abstract

The vascular bundle system in the panicle neck of rice ( L.) connects the culm to the panicle and transports assimilates. The number of vascular bundles in the panicle neck (VBN) is correlated with the diameter of the panicle neck (DPN), but there are few reported QTLs for DPN. We conducted quantitative trait locus (QTL) analysis using recombinant inbred lines (RILs) derived from a cross between 'Asominori' and 'IR24' and detected three QTLs-, , and -on chromosomes 5, 6, and 11. The , , and were in the same position as the QTLs for VBN reported in previous studies. Within the RILs, there was a significant positive correlation between DPN and VBN. In segregating populations, each QTL had a distinct effect on both values. Analysis of chromosome segment substitution lines showed that and affected DPN and affected VBN. Through substitution mapping, we narrowed down the region of and to 960 kbp between KNJ8 Indel385 and RM18926, and the region of to 750 kbp between C5 Indel5756 and KNJ8 Indel493. Due to the weak effect of in the 'IR24' genetic background, the location of could not be determined.

摘要

水稻（Oryza sativa L.）穗颈中的维管束系统连接茎秆和穗部，并运输同化物。穗颈维管束数量（VBN）与穗颈直径（DPN）相关，但关于DPN的数量性状基因座（QTL）报道较少。我们利用‘Asominori’和‘IR24’杂交衍生的重组自交系（RIL）进行了QTL分析，在第5、6和11号染色体上检测到3个QTL——qPND5、qPND6和qPND11。qPND5、qPND6和qPND11与先前研究报道的VBN的QTL位于相同位置。在RIL群体中，DPN与VBN之间存在显著正相关。在分离群体中，每个QTL对这两个值都有不同的影响。染色体片段代换系分析表明，qPND5和qPND6影响DPN，qPND11影响VBN。通过代换定位，我们将qPND5和qPND6的区域缩小到KNJ8 Indel385和RM18926之间的960 kbp，将qPND11的区域缩小到C5 Indel5756和KNJ8 Indel493之间的750 kbp。由于在‘IR24’遗传背景下qPND11的效应较弱，无法确定其位置。
