| Research Abstract |
It is known that there is the genetic difference in SCP (the strength to control the priority of spikelets within the panicle for grain filling) in rice. Data from the experiments using the genotype with high sink capacity recently released showed that the early growth and filling of grains at the lower positions within the panicle (inferior grains) often decrease in varieties with strong SCP, but such a decrease dose not occur in varieties with strong SCP. Therefore, in addition to high sink capacity, weak SCP should be proposed as ideal characteristic of grain filling in super high yielding rice genotype which will be developed in the near future.
