1月季对根结线虫病抗性遗传研究(英文)显示文摘针对月季栽培过程中出现的最严重的根结线虫病防治问题 ,开展了月季对根结线虫抗性遗传研究。研究结果如下 :①对常用的 4种月季砧木R .multifloraK1 ,K2 ,CE63及R .indica对 4种常见根结线虫即南方根结线虫 (Meloidogyneincognita)、爪哇根结线虫 (M .javanica)、花生根结线虫 (M .arenaria)及北方根结线虫 (M .hapla)的抗性进行了测定 ,得出只有北方根结线虫能侵染月季 ,其余 3种不能侵染。②根结指数与对数转化后的每克根中雌虫数、雄虫数、3~ 4龄幼虫数之和、2龄幼虫数、卵数、成虫及 3~ 4龄幼虫数之总和、2龄幼虫与卵数之总和均呈线性相关关系 ,因此根结指数是进行抗性评价的可靠、简单及实用的指标。抗性划分标准如下 :根结指数 0 .0~ 1 .0 ,抗病 ;1 .0~ 2 .0 ,中等抗病 ;2 .0~ 3.0 ,感病 ;3.0~4.0 ,比较感病 ;4.0~ 5 .0 ,高度感病。③以根结指数为指标 ,通过对杂交所得 74个子代的抗性评价试验表明 :在 2抗性亲本所得 1 2个子代中 ,各子代抗性水平存在抗性分化 ,说明抗病基因不是由单一显性基因控制 ;在所有的 62个抗性亲本与感病亲本的杂交子代中 ,5 9个子代均比抗病亲本感病 ,表明抗病基因由隐性基因控制。因此 ,提出了月季对根结线虫的抗性遗传可能由王新荣 Jacob Y Mastrantuono S Bazzano J Minot J C Voisin R Esmenjaud D 2001华中农业大学学报2001,20,3:4
