广西普通野生稻抗白背飞虱鉴定
【目的】从一批广西普通野生稻材料中筛选出新的抗白背飞虱材料,为水稻抗性品种培育和栽培稻遗传改良提供优异的抗性资源。【方法】通过成株期鉴定法对218份普通野生稻进行白背飞虱抗性株的初步筛选,以Ptb33为抗性对照、9311为感性对照;利用苗期集团法对初步筛选到的抗性材料进行抗白背飞虱鉴定,并对部分抗性较好的材料进行重复鉴定,确定试验结果的可靠性。【结果】利用成株期鉴定法从218份普通野生稻材料中初步筛选出60份对白背飞虱具有一定抗性的材料,占总鉴定材料的27.5%。利用苗期集团法从60份普通野生稻材料中鉴定出抗性材料22份,其中高抗材料1份,占鉴定材料数的1.7%,中抗材料21份,占鉴定材料的3...

| Abstract_FL | Objective]New rice materials with resistance to white-backed planthopper (WBPH) were selected from Guangxi common wild rice materials, in order to provide basic materials for resistant varieties breeding and genetic im-provement of cultivated rice. [Method]A total of 218 common wild rice materials were identified at adult-plant stage for preliminary screening with Ptb33 as resistant control and 9311 as susceptible control , so some WBPH-resistant lines were selected from them. And seedling bulk test was used to identify resistance of selected WBPH-resistant lines. Finally , some lines with high resistance to WBPH were re-identified by seedling bulk test , so as to verify reliability of test results.[Result]Sixty WBPH-resistant rice materials was selected from 218 common wild rice species through identification at adult stage, which accounted for 27.5%of total materials, and twenty-two of which was identified as WBPH-resistant ma-terials in seedling bulk test. However, only one material was highly WBPH-resistant, accounting for 1.7% of identified materials, and twenty-one materials were moderately WBPH-resistant, accounting for 35.0%. Furthermore, the repetitive identification results showed that, among twenty-two materials, nine rice materials had high average resistance, this result was consistent with result of earlier identification. [Conclusion]Through resistance screening, twenty-two materials with moderate or high WBPH-resistance are selected from 218 common wild rice materials , which can be used for resistant varieties breeding and genetic improvement of cultivated rice. |
