| Abstract: | According to seed production of Yanliangyou 888, a two-line hybrid rice variety, the research reviewed seed production characters, as follows: to improve outcrossing rate and spike size provided sufficient spikes of female/male parents.The seed production techniques include scientific arrangement of seeding interval,cultivating strong multi-tiller seedlings, scientific arrangement of row ratio of intercropping with adequate basic seedlings, scientific water and fertilizer management,improving outcrossing rate by synthesis measures, disease/insect control, and reinforcing production management. |
