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.
Means in each column followed by the same letter are not significantly different at 5% level according to Duncan’s multiple range test.
