Distribution of the rice lines with clustered spikelets and dense panicle, parents, and Korean rice varieties using number of spikelets per panicle and panicle length (A) and relationship among panicle-related traits (B) and the varieties and lines (C) in the principal component analysis diagram composed of component 1 and 2. Korean rice varieties were classified into japonica (blue round mark , symbol J, n=160) and Tongil-type (green triangle mark, symbol T, n=18). CD indicates rice lines with clustered spikelets and dense panicle (red square mark, symbol CD, n=23) and BH indicates Binhae Col.#1. PL: panicle length, TNN: thickness of neck node, NR: number of rachis-branches per panicle, NS: number of spikelets per panicle, DP: density of spikelets in panicle, NPr: number of primary rachis-branch (PRB)es per panicle, NSPr: number of spikelets on PRBs per panicle, MNSPr: mean number of spikelets on a PRB, NSr: number of secondary rachis-branch (SRB)es per panicle, NSSr: number of spikelets on SRBs per panicle, MNSSr: mean number of spikelets on a SRB, Sr/Pr: ratio of SRBs to PRBs, SSr/SPr: ratio of spikelets on SRBs to spikelets on PRBs.
