水稻育种现状的评价与方向

过去１０年，通过多种育种途径相结合的做法，本校的水稻育种工作取得了可喜的成果，育成了早、晚籼新品系和杂交稻新组合共１５３个。其中，８个通过了广西区级水稻品种区域试验，４个品种、组合通过了自治区品种审定委员会审定，并获得了奖励。然而，大多数育成品系、组合的丰产性、稳定性、抗病性及稻米品质还有待改进和提高。今后，应充分发挥杂交育种途径在选育新品种中的重要作用，多种育种途径互相配合，取长补短；在选育新品种、杂交稻新组合过程中，应拓宽选系的亲缘关系；加强选系的抗病性鉴定；提高选系的丰产性和稳定性，进一步提高育成品种、杂交稻组合的总体水平。

THE EVALUATION ON PRESENT STATUS AND DIRECTIONS OF THE RICE BREEDING

in the past decade,by using various breeding methods,considerable progress in rice breeding has been achieved in our university.153 lines and hybrid combinations of the early or late indica rice have been developed,8 of which were passed the cultivar adaptability test at the provincial level,4 of which have been certified by the provincial commercial cultivar appraisement commitee and received various awards.However,the yield Potential,the yield stability,the disease resistance and the rice quality of most of the developed lines or combinations need to be improved.In the future,it is suggested that the cross breeding method be fully used in the rice breeding,and that various breeding methods be combined to overcome each mathodt's disadvantage and to develop each method's advantage.In developing the new cultivars and hybrid combinations, we should widen the relationship of.the parent lines,and strengthen the diagnostic work of the resistibility to disease and the quality evaluation,enhancing the yield potential and the yield stability of the parent lines to improve the total level of the cultivars and hybrid combinations developed.
