Yanhui 559 is a restorer line selected by the agronomic institutes in coastal areas of Jiangsu Province. There are many spikes and large grains in Yanhui 559 with enough pollen amount, but its species is quite different from that of Minghui 63. It is necessary to grasp its characteristics and techniques for seed production Links, in order to achieve high yield and quality. A reasonable arrangement of heading date. In addition to taking into account the flowering period is conducive to pollination Yanghua climatic conditions, to avoid the high temperature stage is an important part of the technology. Salt Hui 559 pollen is very sensitive to high temperatures. Although no information has been reported before this, and in 1997 the city planted Salt Hui 559 on August 8
