The newly bred heavy panicle large-grained japonica rice Iksan 435 and Iksan 438, HR14022-21-8-4 and HR14022-21-8-6 with many spikelets per panicle, and control Dongjinbyeo and Donganbyeo (many panicle types) were grown under standard (30x15 cm) or dense planting density (15x15 cm) with 110 or 165 kg N/ha. Percentage effective tillers decreased with denser planting or higher N rate, while leaf area index and shoot dry weight increased.
