| Abstract: | Gangyou 725,a hybrid combination of medium indica with late maturity,is characterized by stable and high yields, good grain quality and wide adaptability- It is now being extended to a very large area. In order to explore the mechanism of its high yielding potential,a study on characteristics of its dry matter accumulation and distribution was conducted. The results showed that the dry matter of subsecific heavy-ear hybrid rice Gangyou 725 accumulated much more dry matter than Shanyou 63 with the same maturity. The dry matter accumulation in the middle and late growth stages, the development of root systems and leaf area of Gangyou725 were higher than Shanyou 63. |
