【摘要】 运用ＲＡＰＤ技术进行了西瓜野生材料ＰＩ４８２３２２耐冷性基因连锁的分子标记的研究，找到了一个分子连锁标记ＯＰＧ１２／１９５０与耐冷基因连锁，其遗传距离为６．９８ｃＭ。更多还原

【Abstract】 Random Amplified Polymorphic DNA(RAPD)was employed as a tool to detect molecular markers linked to the chilling tolerance gene slv + in the watermelon Citrullus lannatus (Thunb.)Mansf .OPG12/1950 was proved to be linked to the gene slv +by co segregation analysis with F 2 population.The genetic distance was measured 6.98 cM and LOD was 23.1.更多还原
