In their study based on data collected in 1990, Byerlee and Moya (1993)
calculated the percentage of varieties released by height (semidwarf or tall) and

Semidwarf breeding Southern China has frequent storms and torrential rains,
causing rice to lodge and resulting in very low yields. I therefore established the
following rice breeding targets: semidwarfs; combining higher ability to use
