Male parent of hybrid rice seed implantation technology to improve

The use of hybrid rice seed production paternal line of wide and narrow lines, the two phases of the male parent and his play, according to the paternal line of the two ＂goods＂-shaped implantation, the expansion of parents in this space, such as male parent implantation of the new technology is con- ducive to male parent And close to the Father of our parent＇s individual growth and development and pollination, increase the rate of outcrossing strong, single male parent to avoid transplanting the way out after the male parent powder vulnerable to the phenomenon of discount lodging, to overcome the sopho- more paternal line implantation because of the way male parent Take up too much space and less than the drawbacks of the female parent ears, is a high and stable yield of technical configuration.
