| 中文摘要: |
| 采用经典遗传分析方法，对来源于美国辣椒疫病抗性资源 ‘CM334’的疫病抗性遗传规律进行了研究。试验将‘CM334’与疫病高感自交系‘949’配制杂交组合，并构建杂交组合的6个世代（P1，P2，F1，F2，B1和B2），用苗期伤根灌根接种法对其各世代群体植株进行抗性鉴定, 并进行χ2的适合性测验。结果表明: ‘CM334’的抗疫病性状遗传符合一对显性基因控制模式。 |
| 英文摘要: |
| The inheritance of the variety ‘CM334’ of hot pepper from America, resistant to Phytophthora capsici, was studied by the traditional genetic analysis method. The six populations (P1, P2, F1, F2, B1 and B2) derived from the crosses between highly resistant inbred line ‘CM334’ (P1) and the highly susceptible inbred line ‘949’ (P2) were sowed in nutritive cups. The resistance of the plants of each population was evaluated by irrigating method, and the segregation ratios between the resistant and susceptible plants in F2 and B2 populations were analyzed by χ2 test. The results showed that a single pair of nuclear and dominant gene controlled the resistance in the inbred line ‘CM334’. |
