3 Karemary Central Physiological characteristics ornamental trees compared Crosses of the four parents, so called four-line hybrid rice. Four-line hybrid rice seed production is not only high, and relatively easy to obtain a good combination of resistance. But the four lines to keep lines of two stages and plant height to be very close, and the recovery of the genetic ability to be strong, otherwise can not guarantee uniformity of hybrid rice. 3 Conclusion and discussion in the improvement of 4 methods on the Application IB58025A different. Mutation shorter incubation time for the new CMS, M or M2 can be obtained stable lines,ugg boots, it maintains the characteristics of the original species IR58025A, but the outcrossing rate is limited, the current level of up to 50%. Outcrossing breeding rate depends on the degree of parental choice, the new CMS bred with the original species are very different kinds of rice quality is difficult to maintain the original level. Outcrossing rate and high backcross breeding, the best materials,jordan shoes, the outcrossing rate can catch up with the level of conventional rice seed setting rate,moncler outlet, basically to maintain the original species traits, it is worth noting that rice quality is often in different degrees of deterioration . Come the fastest four-line, but the growth period in our country does not maintain a similar system with 1R58025A not yet applied successfully in the IR58025A.
