While government breeding efforts have tended to concentrate on basic cereals such as rice and wheat, economic growth and rising living standards have brought increased consumer demand for high-profit horticultural products like flowers and fruit. Farmers now devote more growing area to these, new varieties are being introduced, and private-sector involvement in variety development is on the rise.
但政府育種大多以基本糧食如稻、麥等五穀雜糧為多，隨著經濟不斷發展，生活水準提高，消費者對花卉、水果等利潤較高的園藝作物需求增多，農民栽培面積拓廣，花卉、水果又講求品種推陳出新，私人投入品種開發的情況便日益增多。
