| Abstract: | Through two years observation and seed producing practice,the characters of Teyou103＇s parents and its highyield seed production techniques were summarized.The key of seed production is selecting right sowing period.In order to guarantee high-yield and abundant harvest,it should transplant at right time to breed multi-tiller seedlings,rational close plant to promote coordinated development of parents＇ colony structure,enhance management of fertilizer and water to create high-yield colony structure,scientifically spray gibberellin to improve outcrossing rate,roguing the weak rigorously to ensure the quality of seeds,and strengthen the control of disease and insect pest. |
