Abstract:

品种间亲缘系数是研究作物品种间遗传关系和遗传多样性的重要方法.对华南地区不同年代育成的常规籼稻主栽品种的亲缘系数进行了分析.结果显示,近50年来华南地区基于亲缘系数的水稻品种遗传多样性呈“W”型变化,3个高点分别出现在1957年前、1970—1979年和2000—2008年,3个低点分别出现在1957—1969年和1980—1989年.基于亲缘系数的品种聚类结果较直观地反映了近50年来华南地区籼稻品种的遗传关系及其品种演变特点,与该地区不同时期主要围绕着少数几个骨干亲本进行品种改良的特点相吻合.本研究获得的华南地区近50年来水稻品种遗传多样性呈“W”型变化这一结果说明,基于品种间亲缘系数的华南地区品种遗传多样性未经历持续的下降或上升,而是在一定范围内波动.
