| 摘 要： | 在田间条件下人工分小种接种寄主品种,根据各品种×小种组合的病情估计相对适合度,结果表明多数主栽品种与29号小种组合的适合度估值较大,这与近年29号发展为优势小种的实际情况一致,但是,测定值在不同试验中相差甚大,毒要原因可能是待测品种与对照品种对发病条件的敏感性不同。 |
| 关 键 词： | 适合度 选择系数 生理小种 专性寄生 |

| Abstract: | Wheat varieties were inoculated with each of yellow rust races in field.According to the infection type,severity and incidence of variety * race,the fitness was estimated.the results were reasonable to some extent,but the control variety differed in susceptibility to the factors affecting disease development from the variety to be tested. |
| Keywords: | fitness selection coefficient physiological race |
