Summary


Originally native rice variety (Tai nguyen duc) and mutant rice variety induced by Tai nguyen duc variety (Tai nguyen dot bien) were used for our research. The new mutant rice variety has some better characters in comparison with those of the Tai nguyen duc such as photoperiodic insensitivity, earlier maturity in the summer crop, higher tillering capacity, shorter plant height, smaller angle and shorter of flag leaf, transparent and longer grain, greater number of grain per panicle, more bright yellow grain, expected yield greater twice, better resistance to yellow stem borer and brown plant hopper.

The inheritance research was conducted by Tai nguyen duc variety and Tai nguyen dot bien crossing combination. The research’s results from F1 and F2 show that: the mutation generates transparent grain is dominate and transmitted to offring from mendenian ratio in monohybrid (ratio 3:1); the mutations create photoperiodic insensitivity, long panicle and long grain that are recessive and transmitted to offring from mendenian ratio in monohybrid (ratio 3:1). Other mutations that generate earlier maturity, short plant height, high tillering capacity, short flag leaf, small angle of flag leaf are incomplete recessive and transmitted conform intermediary mendenian monohybrid (ratio 1:2:1).
