WebApr 21, 2024 · However, the high yield potential of ‘super’ rice cultivars, which have numerous spikelets with a large capacity, frequently fails to manifest in high grain yield due to either sterility or slow or poor filling of inferior spikelets. WebAbstract Poor grain filling of inferior spikelets is becoming a severe problem in some super rice varieties with large panicles. Moderate soil drying (MD) after pollination has been proven to be a practical strategy to promote grain filling. However, the molecular mechanisms underlying this phenomenon remain largely unexplored.
