Performance of aerobic rice varieties under irrigated conditions in North China

In Northern China, high-yielding aerobic rice varieties are released to farmers to grow rice as a supplementary-irrigated upland crop to cope with water scarcity. If the key factors contributing to the high yield of these varieties are understood, rapid advancements can be made in developing aerobic rice varieties for water-scarce environments in other parts of Asia. In 2001–2002, we conducted experiments with aerobic varieties HD502 and HD297...
