Study on Biological Characters of Jinmai 60 and Its High Yield Cultivating Techniques

Tiller ability of Jinmai 60 was strong. Jinmai 60 belonged to twice-tillering peak type. Its ear differentiation was slow prophase, quick late stage and short organogenetic period. The grain filling process expressed the characters of slow-quick-slow. The integrated cultivation techniques of Jinmai 60 should take stabilizing ears, raising grain number and grain weight as key task. The rational-high quality population was established by adopting constant fine seeding technique. The yield index of 8 250～9 000kg/ha should be achieved by scientifically water utilization, balanced fertilization, “three-spraying exercise”, and disease and insect prevention in order to raise grain weight.
