The rapeseed production in China has been increased steadily since 1980s, especially in 1990s. The yearly average planting acreage of rapeseed is 6.25 million hectares, from 5.70―6.90 million hectares. It is three times of the planting acreage in 1950s-1960s. And the total production has been increased 10 times since then. The total vegetable oil production at present is about 7.5―8.5 million tons, but the consumption is about 11 million tons, shortage of 3―4 million tons There are 90 double low cultivars registered officially in China during 1985―2000, of which 61 are OP cultivars and 29 are hybrids. The yield potential of the best double low OP cultivars is about 5% higher than that of the double high check, and the best hybrids are about 15%―20% higher than the double high check. It is predicated that: the planting acreage can reach 7―8 million hectares in 5―10 years; the acreage of transplanting rapeseed will decrease; double low cultivars will replace double high cultivars in 3―5 years; the planting acreage will increase; cytoplasm male sterility and genie male sterility are still the important two way for hybrid breeding; the planting acreage will be over 50%; besides the high quality and the high yield, high oil content and good disease resistance will be two important breeding aims; the processing level of rapeseed products will be improved greatly.
