Abstract:
     The said breeding technology features that it uses indica rice restoring line Wanhui86 as male parent indica rice sterlie line II-32A as female parent, total parent amount of 24-27.5 Kg/ha with weight ratio of male to female parent seed of 1 to 3.0-3.4, synchronous seeding of partial male parent and female parent in the first stage and seven days postponement of male parent seeding in the second stage, and no leaf cutting of female parent. The present invention as one new type breeding technology can solve the main problem in mechanized breeding and makes the male parent seed and hybrid seed easy to gather and separate machanically.
