ANALYSIS ON PRESENT SITUATION OF RICE BREEDING AND DISCUSSION ON FUTURE RICE VARIETY IMPROVEMENT IN FUJIAN

Agronomic characters genotypes for 18-commercial varieties were analysed during the last decade in Fujian.The result indicated that most of them succeeded the descent of variety "Ai-Zi-Zhan" and its derivative varieties such as "Zhen-Zhu-Ai", "Zhen Shan" and "Zhen-long 410". Therefore, their yield potential and resistance to blast are evidently increased.In future, it is necessary to continue the development of the superior genetics of "Ai-Zi-Zhan" and to transfer some available hetero-gereous and wild rice genes into new strains(or breeding lines)for further progress.The innovations on rice breeding techniques are as follows: 1.Selecting donor parents making hybridization combinations, and utilizing the doner parents, the cultivars insensitive to temperature and photoperiod, and other special breeding lines. 2. Treating the hybridi-zation generations, such as selecting the individual plant from F1, F2…, screening those plants with different resistibility. 3. Application of the method of recurrent breeding.
