| 摘 要： | 对53份水稻品种进行了抗玉米象的筛选.根据敏感系数的差异,鉴定出抗级品种39份,中抗品种3份和敏感品种11份.并证实了应用自由选择和非自由选择的筛选方法,其趋势基本一致.敏感系数与谷粒的裂颖率呈极显著正相关,与米粒的粗蛋白、总淀粉、支链淀粉和直链淀粉含量及糊化温度无明显的相关性.

| Abstract: | This paper deals with the resistance of rice variety to the maize weevil. Of the 53 rice varieties tested, 39 exhibited resistant and three moderately resistant. The resistance that was evaluated on the basis of no-choice screening test had the same trend as that based on free choice screening test Highly significant positive correlation (P<0. 001) existed between susceptibility index and percentage Of gaping glumes.No corrlation (P>0. 05) between protein, starch, amylopectin, amylose content, gelatinization temperature and susceptibility index was demonstrated. |
