The aim of this experiment is directed to find out the effect of lodging on spikelet characteristics of each part of panicle. Rice panicles of normal and lodging ones can be divided into three parts : the tip, the middle and the base. For the purpose of study, physical characteristic of each part panicle such as the weight of panicle, the weight of spikelets, the amount and the weight of filled spikelet, the amount and the weight of 1000 filled spikelet are observed. This also followed by observation on physiological characteristics of panicle. This include the percentage of the filled spikelet and partially filled + unfertilized spikelet, potential germination, standard germination and seedling vigour. Lodging, when its close to harvest time, tend to reduce the physical characteritics of the panilcle but there is no effect on its physiological characteristics. The weight of spikelets from the panicle of lodging plant are lighter 25.5 percent than those from panicle of the normal plant. The location of the spikelet in the panicle influenced the amount and the weight of partially filled + unfertilized spikeled, the percentage of filled and partially filled + unfertilized spikelet in the panicle as well as the physiological charecteristics of filled spikelet. The physiological characteristics of filled spikelet of the tip part of panicle are better than those in the base part of panicle
