Zhuliangyou 02 is a hybrid rice from Zhu 1S, as the female, and ZR02, as the male. We studied the germination rates of Zhuliangyou 02 under different treatments including dehydration, storage variation, and seed soaking, and used Lu 18S/ZR02, H155S/Hua 284, Zhu 1S, and Nipponbare as controls. The results obtained show that the rates of dehydration of air-drying and cold-drying were the quickest and slowest. The germination rate of fresh seeds of Zhuliangyou 02 was higher than the stored seeds and it decreased after aging treatment. Taken together, Zhuliangyou 02 seeds were not resistant to high temperature, high moisture, or long storage. The harvested seeds would exhibit longer lives and improve germination rates if they were dehydrated by quick air-drying at 35°C, stored in air-proof container and intermission soaking performed.
Key words: Zhuliangyou 02, dehydration, storage, seed soaking, germination rates.
