对晚籼弱感光型杂交稻的适应性及其稳定性参数分析的结果表明，博优大占、博优１２２ 和博优８８０ 具有很好的丰产性，但适应性和稳定性稍差，应采用“良种良法”，加强栽培管理措施，充分发挥其增产潜力。目前生产上广泛应用的品种博优９０３ ，由于种植年限的延长，抗性、丰产性和适应性都不断下降，宜选用抗性和丰产性好、米质优的博优１２２ 、博优大占加以替代 The adaptability and stability parameters of late indica hybrid rice with weak sensitivities showed that Boyouzhan, Boyou 122 and Boyou 880 had good yield but poor adaptability and stability, and should be used “Good seed law,” strengthen cultivation and management measures, give full play to their potential yield. Currently widely used varieties of production Bo You 903, due to the extension of planting years, resistance, high yield and adaptability are declining, should use good resistance and high yield, good quality rice Boyu 122, Be replaced
